Thanx for posting the results of your "test!"  This will save me the
trouble of performing similar experiments here.  I never thought about
valve flutter - that's a great theory!  I wonder if there is a way to
modify the BPV to eliminate this problem...

Would someone with a stock BPV off the car please take a look and see if
anything looks adjustable or servicable?  Thanx!

I have a spare one that I got from Todd Shelton.  Unfortunately the valves
for all years are not interchangeable as they changed where the outlet is
for '94 and later to clear the tranny linkages, so I couldn't try it to see
if the older version makes the noise on my car as well.  Looking at the
valve, there isn't really anything adjustable.  There's a hole in the middle
of the valve disc, but that is plugged by the actuator arm.  It might* be
possible to crush it like the DSM guys do, but I'm not sure that's really
what we're looking for.  More spring pressure might do it, which crushing
the valve would do.  However, it might cause more compressor surge if the
valve doesn't open as well as it did uncrushed.  It holds boost just fine
all the way up to 17+ psi, which is more than enough for the street.

As near as I could tell, it would be really tough to disassemble the valve
and reassemble it as the metal part of the valve is "crimped" onto the
plastic part.  I think uncrimping it would damage it enough so as to make it
unusable once reassembled.

At some point I'm going to reconnect the Blitz BOV and plug up the hoses
that went to the stock CBV, but I'm uncertain as to how I should go about
adjusting the spring on the Blitz valve (how do I know how much spring
pressure is right?).

I note the same observations with my 1995 BPV. The service spec calls
for it starting to open at 16". Mine starts to open at 15". Could this
be the sign of a weakening spring? Anyway, so far my 1st gen DSM valve
is still working great. Have about 300 mi. on it now.

Subject: Team3S: SplitSecond ARC-GP2 update (veeery long but interesting)

Attention : A lot of questions, answers and comments... but good stuff (I
hope) :)

Thanks to George, we got the confirmation that the system works on our cars
as slight modifications to the ARC system have been made to get it running
on our cars. As you all know I'm at first skeptical if there are any
unanswered questions around, so I emailed Eric Nist at SplitSecond (thanks
Brian for the connection) with my questions. Here are the answers I got at
the beginning of this week and my comments so far (Q = my question, A =
Answer, C = my comment)

Q :
- - SplitSecond says the following : "The alteration or addition of
turbochargers, superchargers, fuel injectors, fuel regulators, throttle
bodies, intake plenums, Mass Air Flow (MAF) sensors or Manifold Absolute
Pressure (MAP) sensors changes the air/fuel ratio." Can you please explain
me why adding a MAP sensor changes the A/F Ratio ?

A :
That statement refers to the conversion from a 1 bar MAP sensor to a 2 or 3
bar MAP sensor.  Systems that are originally MAP based can stay MAP based
and operate at higher boost levels with an appropriately sized MAP sensor.
The idea of using an ARC2 in this application is to properly fine tune an
engine where the MAP sensor and injectors have been changed.

C :
Ahh, therefore not adding but changing to a MAP with a wider range is
possible, makes sense. As we don't need this feature on our cars we can
leave it out.

- -------------------------

Q :
- - The ARM1 is a necessary tool but it is nothing different than any other
A/F meter !! It contains one small integrated circuit, 10 LEDs, up to three
resistors and one or two capacitors. Worth about $10.. but it works. But
what about an IDC ?? Besides an A/F meter I think EGT and IDC are the most
important values I need to know to tune the stuff properly. Ok, it's not
necessary to observe the IDC all the time but I'd like to know what the
current conditions are ! Why do the ARCs not have this feature ?

A1 :
The ARM1 is an air fuel ratio meter that is specifically designed to provide
useful information to the driver during driving conditions.  It has many
features that combine to achieve that goal.  It has a five color display
that may be viewed with peripheral vision.  It has night dimming so that the
display can be very bright during the day.  It has signal filtering to
optimize response.  It has a differential input circuit for high accuracy in
the presence of ground noise and DC offsets.  These are just the standard
things that we tell people.  There is even more to it than that.  Your
statement above indicates that you don't really understand what the ARM1 is.
It is unique in the industry.

C1 :
Well, the night dimming is definitely a good feature and also the
differential input to make sure that there is as less noise as possible is
also good (an additional OpAmp). But his answer is less than expected. I'd
love to see a picture with the ARM1 box open !!

A2 :
EGT and IDC are also important parameters to interpret and monitor when
tuning an engine.  The ARM1 provides useful information over the entire
operating range of the engine.

C2 :
The ARM1 is a $139 multimeter that reads the O2 sensors. You need an A/F
meter to tune the stuff in and if the ARM1 is within the kit we have to live
with it.

- -------------------------

Q :
- - It is not really clear what the GP style of the ARC is.

A :
The ARC2-GP is a version of the ARC2 that is specifically designed for the
3000GT.

C :
I guess this should mean that the hardware in the ARC has been adapted for
the bigger airflow on our cars.

- -------------------------

Q :
- - A a good system MUST check the boost pressure in the manifold and adjust
the signal
automatically that goes to the ECU. We know that the most of our cars do not
have a MAP sensor and therefore the ECU calculates the boost shown in the
stock meter. A sophisticated aftermarket fuel control or MAF conversion
system must take care of this to provide the full advantage but the ARC
cannot find out on what load the car is just by measuring the air flow.
This is the advantage of the VPC although it converts your car into speed
density.

A :
The VPC does not convert your car to a speed density system.  It uses MAP
and RPM to calculate flow information.  It is far better to stay flow based
which is the way the ECU was designed. In practice an ARC2 based system will
proved more accurate calibration over the entire engine load range.

C :
After thinking about the VPC stuff, I must say that Eric is absolutely right
! The VPC does not convert your car into speed density as it reads three
parameters : Boost, RPM and Intake air temp. More on that later.

- -------------------------

Q :
Also the adjustments (VPC) are pretty close the same way as the ARC.

A :
The operation of the ARC2 is unique in the industry.  No other calibrator
works like it.  In other words, no other calibrator provides the range of
adjustment with such a small number of controls while providing smooth
response.

C :
This is not much more information.

- -------------------------

Q :
- - SplitSecond says : "This package will allow you to raise the boost,
install larger injectors, even change to larger turbos".

Ok, I think we can always change to larger turbos without the need for the
ARC ;-) Anyways,
the first point is not true if the fuel system has not been modified yet.

A :
Changing the size of the turbo effects spool response and back pressure
which effects the horsepower gain per pound of boost.

C :
I think that this means that after installing bigger turbos the ARC can be
tuned in again to the new variable (sure).

- -------------------------

Q :
Or how does SplitSecond controls the engine detonation or how do you know if
the
injectors are at their limit ?

A :
The injectors have to be sized properly for the application.  Once the
turbo, injectors, flow sensor etc. have been properly specified, the ARC2
can be used to fine tune the calibration.

C :
Yes, this makes absolutely sense ! I didn't thought about the fact that we
also have to tell HKS what injectors we have so they provide the right EPROM
for the $$$ box. Taking the ARC kit means that you NEED at least bigger
injectors (I'd also upgrade the pump too). There is no need for bigger
turbos but if you change them later you can recalibrate the ARC for the
higher flow (of course).

- -------------------------

Q :
- - I'm missing any idle speed control for larger injectors (e.g. 720cc) ! It
does sense the TPS and therefore knows when the throttle is closed but what
is the behaviour during shifting ? Are the rpms included in the sensing
signals ?

A :
By staying flow based and using the ARC2 you can accurately tune at idle.
We do not use an RPM input on the ARC2.

C :
Makes sense again. Air flow is really low at idle and it seems that the flow
sensor is able to sneak this and the ARC can give the right frequency to the
ECU in this case. As George had slight problems with the idle (solved now
??) I guess some slight adjustments for the lower flow area is necessary. I
still wonder how the thing acts when shifting hard/soft and the behaivour
under cruise control conditions.

- -------------------------

Q :
- - How does the ARC box know when the car is under load and what boost the
car runs on ?

A :
Load and boost are directly related to flow.  That is why we stay flow
based.

C :
Yes, this is absolutely true. There is a formula that calculates the airflow
rate and includes the boost pressure rate as a multiplier. The aim of my
question was to find out why SplitSec doesn't use a MAP sensor and this is
the answer: Both values are in the formula and changing one affects the
other. More to this interesting topic later.

- -------------------------

Q :
Also how is the load of the car known and is this
programmable in the ARC ? Is the ARC programmable anyways ?

A :
The ARC2 is universal.  It will operate with whatever maximum load the
engine is running.  The key is for the flow sensor and injectors to be sized
properly for the application.  All adjustment of the ARC2 is done through
the four front panel controls.

C :
Full load = full capable boost = air flow@rpm. This simple equation makes it
easy to tune the ARC in. Once done only response has to be adjusted to find
teh best gain.

- -------------------------

Q :
My conclusion is that the larger MAF is a good thing. It will keep the car
mostly as it is and by adapting the signal to the ECU it works for a wide
range of cars, but the price is very high for a "frequency altering
device".
Even more, the thing seems not to be intelligent and doesn't help in any
situation (it is fully manual) nor does it know what to do in any boost
situation.

A :
The ARC2 generates a best fit curve to operate over the entire range of the
engine (every day driver or weekend warrior).  This provides maximum power
while preserving OEM quality and drivability.  The ARC2 works with the stock
ECU to provide fine tuning and driver adjustability.  It is your best choice
for retaining factory drivability when retaining the stock ECU.

C :
That means that any programming feature is just not necessary. The key word
is "every day driver". This is where I think the VPC is not at its best.

- -------------------------

Q :
The VPC is also somewhat old fashioned and it's bad to have a new EPROM
burnt for other injectors. Well, I think I'd the injectors only once :).
Also it converts air-mass systems to speed-density systems that is not the
most wished thing. And together with a GCC price is way too high.

Comparing the ARC to an Apexi S-AFC doesn't make sense at all as the later
is a fine tuning tool and good for somewhat larger injectors like 550cc.

A :
The ARC2 is unique in many ways, one being that it does a mass air flow to
Karman Vortex conversion.  The signal conditioning circuitry is very high
performance and responds very rapidly.  This is key to maintaining OEM
quality of drivability.

- -------------------------

Q :
my point of view, the three nobs saying Low,Mid and High do almost the same
(like the VPC knobs)
but with another philosophy and terminology. It does nothing else but
giving you an alternated fuel curve over the air-flow or rpm band.

A :
Needless to say the ARC2 does a lot more than that.  The low mid and high
knobs provide a convenient user interface, yet the functions they serve are
quite sophisticated.

C :
Yes, it does convert the signal into Karman Vortex style and what I've
asked. But what is a lot more ?

- -------------------------

Q :
In my point of view, the ARC as well as the VPC are only half the way to the
right solution. The TRE MASC was pretty close but maybe too complicated and
finally too expensive for the market to make real money out of it. What we
need is : .....

A :
I am confident that the ARC2 is going to provide the adjustability and
performance you are looking for.  If you want a lot of data logging and
serial interface features, you may want to look at a stand alone aftermarket
ECU.

C :
Hmm, it seems to be wishful thinking that we'll get a system that provides
us with all the information on the parameters the thing is working on. As
said the TRE MASC was a good system and I wish the thing would have been
continued.

- -------------------------

Q :
I was also told that the Stealth with the ARC2-GP runs with limited boost
of 1.15 bars. Why ? The musics starts to play above 1.2 bars for sure. Also
the 13Gs are able to go over 1.35bars !!

A :
There is no reason why the ARC2 can't work at higher boost levels.

- -------------------------

Q :
Also the stock turbos (or the 13Gs) do not suck more cfm in than the stock
MAS already can deliver so what is the gain of the MAF ?

A :
The lower restriction of the MAF sensor makes the turbo more efficient and
enhances spool response.

C :
I would like to see this directly on the dyno with the stock (13G) turbos
and the stock fuel system and boost of 1 bar; just to see the difference.

- -------------------------

Q :
I'd say with a simple fuel controller (e.g. the ARC without the MAF) you'd
have the same results with the 550cc injectors. Comments ?

A .
The MAF provides less pressure drop across the sensor leading to higher
efficiency and therefore more power.

- -------------------------

Q :
Last thing : We'll get the real gain when we can increase boost. But we are
limited to the fuel system and how much fuel the cars need to prevent knock
(wasting energy !!).

A :
The fuel system must be matched to the requirements for the amount of boost
you are making.

- -------------------------

Q :
So how do you tune in the stuff without a knock monitor
and without the ability to see the timing is getting retarded ?

A :
If your ECU is retarding the timing due to engine knock, the cheap fix is to
throw more fuel at it.  A proper fix would be to address the back pressure
of the engine's exhaust before and after the turbo.

C :
Of course, the ARM1 is used at first for tuning in the proper A/F ratio.
Then we have to be careful with increasing the boost. Unfortunately we do
not all have an AWD dyno a few minutes away :( But this problem do all
systems have and is not addressing the ARC.

- -------------------------

Well, that's it (do you have already some headache ?)

I got some headache today thinking around this stuff as we all know that
bigger turbos flow more air at the same pressure. Therefore I expected that
the measured air flow with larger turbines increases while the boost stays
the same. I'd say yes. Therefore just adding a 15G over the 9B and running
still 15 psi will result in bigger power due to the more air that is
compressed. Unfortunately, there is a formula to calculate the airflow rate
:

(in^3 * rpm * 0.5 (const) * 0.9 (vol.efficiency) * Press.Ratio) / 1728
(const) = cfm

And there is nothing that points to a variable device like the flow or
efficiency of the turbos. The displacement is still the same as well as the
pressure and therefore the air flow stays the same with the bigger turbos.
But of course, the compressed air is denser and the bigger turbos are able
to provide the desired cfm when the rpm increases. Using this formula on our
car gives us the following :

Stock Wategates open :
(182in^3 * 7000rpm * 0.5 *0.9 * 1 (0 bars of boost)) / 1728 = 332 cfm

Stock 0.5 bars:
(182in^3 * 7000rpm * 0.5 *0.9 * 1.5 (0.5 bars of boost)) / 1728 = 498 cfm ->
249 cfm per turbo

Modified 1.3 bars :
(182in^3 * 7000rpm * 0.5 *0.9 * 2.3 (1.3 bars of boost)) / 1728 = 763 cfm ->
382 cfm per turbo

Modified  1.5 bars :
(182in^3 * 7000rpm * 0.5 *0.9 * 2.5 (1.5 bars of boost)) / 1728 = 829 cfm ->
415 cfm per turbo

Back to the SplitSecond ARC-2GP System, the formula tells us that with
increasing boost a much better air flow system as well as fuel upgrade is
needed. The injectors are easy to calculate :

Say our aim is 400hp => (400 x 0.55) * 10.5 / 6 = 385cc

Do you remember that we dynoed the cars around 400hp and that we found out
that the IDC is pretty close or even more than 90%. Now you know why ! This
only works as the fuel pressure is already pretty high and I doubt that
increasing the pressure would be healthy for the injectors.

Now our aim is 500hp => (500 x 0.55) * 10.5 / 6 = 481.25 cc

The next size are the 550cc and should be enough for this purpose. Of course
the flow needed is not calculating with cooling the chambers .. and this is
not possible to calculate as there are too much unknown paramters. I was
told that this can be up to 13% i.e. need of 543cc injectors. The best is to
watch the IDC to find out where you stay.

The ARC provides now a better air flow causing the turbos to spool-up more
free and is able to control the new bigger injectors without a problem.
Having more information now I think that this is pretty easy with the
SplitSecond stuff. Also due to the calculations shown above, we see that
there is definitively more air and better flow needed. A VPC and ARC both
provide us with with these enhancements while a VPC needs to be programmed
too. And if you see that there are even bigger injectors needed you have to
get another chip for it again. This is definitively the weak point and
here's where the ARC wins. I'm also positive that the low boost area and
idle behaviour is better than with the VPC. I can't say how much the
influence of intake temperature has as I don't know if the SS MAF measures
the temp as well. As we do have very different temps over the seasons I
definitvely need a system that is able to compensate on this.

That's it for now ... and stay tuned for more :)

Subject: Re: Team3S: fuel system upgrades

Dave is very right and I second his statement on our enemy.

To make thing a little bit clearer, with a 3S having a larger air filter and
boost crnked up in any way fuel cut appears around 1.25bars / 18 psi. I
never hit FC with 17 psi with a healthy engine. This became worser and
worser as the the damge was there and some oil has found its way into the
chamber. Oil in the A/F mixture causes  to reduce the octane rating that
finally results in earlier detonation !! And if the ECU is not able to
retard the timing anymore and knock still exists it initiate FC. I finally
got it at 1.07bars :((

Avoid detonation !

Hi Chris,
Thanks for your input, Chris; My buddy (he owns a muffler shop) & I
have attempted several times to free that rear strut up!  But it is Frozen
solid!  We were hesitant to torch it up due to the fact that we'll melt that
rubber bushing - but you're saying that you were able to torch it without
melting it?  Nobody has JUST the rubber bushing available?   Has anyone else
run into this problem?  Should I just go ahead and torch it?  If it melts the
bushing away; I will have to buy a whole new rear strut assembly!

Any input would be appreciated,

Subject: Team3S: tire replacement

Hello guys

I recently purchased a '95 VR4.  Unfortunately the car is due for a new set
of tires.  What I noticed on the car is that the rears are really worn while
the front look fine.  I would believe this is due to a neglection by the
original owner in regards to tire rotation.  The car only has 38K miles so I
believe these are the original tires which are OE Yoko's.  My question, is
it possible to change only the rear?  My concern is that an "all wheel
drive" car is sensitive to wheel diameter differences, but how sensitive?
FYI the fronts have about half of the tread left while the rears are about
1/8 left on them.  I know it may be possible that the original owner may
have replaced the fronts only at some point which would account for the big
difference in wear.  Would replacing only the rears cuase any type of
drive-train problems?  Hate to waste two good tires.

Thanks
Len '95 VR4

Ahmed...

Perhaps I got lucky, but it didn't melt. Replacement bushing? How about a
wrecking yard? Also, there's a number of aftermarket bushing companies
around (should be some on the web). Quickor Engineering is the one I used to
replace all my rubber bushings with polyurethane (for a 1967 Mustang). My
guess is, unless we got lucky and found a size from another make/model that
fits, there isn't (and won't be) enough volume to get anyone to step up for
mass production. For the swap, you'd need ID, OD, Thickness and some measure
of density. Outside of that. you're stuck with a custom part. Spendy.

Good luck with a tough decision!!!

Looking forward...Chris

Subject: Team3S: knock sensor and A/F guage

Hey everyone,

A buddy of mine is having a problem and he needs some help from the experts.
He is having some trouble subscibing to the list so I'll try to explain the
problem and hopefully some of you can e-mail him privatly with your advice.

Last night, John and I installed a boost gauge, A/F gauge and a cut little
LED for a knock indicator.  John used some instructions for the knock
indicator from a DSM website and the scematics for the 3/S.  After we
installed it, the A/F gauge(Autometer) was going all over the place.  An the
knock indicator was staying lite.  The DSM instructions said to reset the
ECU if the LED was staying lite.  So we unhooked the battery for 30 minutes.
After that, the indicator would go off when accelerating, but come back on
at idle.  I doubt his car is getting knock at idle.

Please e-mail John privatly if you can help him out.  He is a good mechanic,
just not very experienced with modifying a 3/S.  (like most of us)    His
e-mail is:  jbasol@carlson.com

Thanks a bunch,

Hello,

   Quick question:  If you were to install rear (and/or front) struts
without the rubber bushing, what kind of performance differences would one
expect to notice?

THank you for your time.

Leonard...

Most likely the previous owner rotated the front to rear, as the fronts
should show more wear than the rear. My guess is, if you leave them the way
they are now, you should wear out all four at about the same time. On our
cars, I would NOT mix sizes or brands. The AWD, AWS steering systems would
likely be thrown out of whack (technical term  :-)) and you'll have more
problems that you need. Handling would also be adversely affected.

Looking forward...Chris

Dennis...

Well, first off, you'd have 3/4" of free play on both sides of the shaft.
This would rattle and clank every time you hit the slightest bump. Also, the
jarring, without the bushing, might actually fracture the mount. It could be
done, but certainly wouldn't be practical. Better yet, If a person knew how
dense the bushing material is, and had access to a machine shop and some raw
material (rubber or polyurethane), they could make one of their own.

Looking forward...Chris

Subject: Team3S: Wind noise

I just went back and forth to Chicago on I80 & 88, running at 90-100 mph,
with short blasts up to 120 when conditions permitted (trucks for screens,
wide open highway, etc.)  I go to my office twice a year, whether I need to
or not.

It's nothing like running on the autobahn, of course, but I did manage to
cover 247 miles in 3 hr and 10 min, complete with toll booths,
construction, Chicago-area traffic, and one pee stop.

At 90 mph, the speedo is straight up, the tach reads 2800 rpm, and the car
is in the sweet spot between those nasty goose honking sounds at 85 and 95
mph.  Surely our cars were designed for 90 mph cruising. In Iowa (65 mph
speed limit), they take your license for 25 over, which is why I mostly
cruise at 90 and not 100. I figger if I stab the brakes when the detector
goes off, it will get me just below 90, avoid the nasty penalty, and just
get me a speeding ticket.

However, the wind noise at 90-110 mph is annoying. I hear wind hissing and
blowing around both windows and the roof glass. Any idea what to do about it?

BTW, only two cars kept up: a 535 BMW, who hung on doggedly, and a
nondescript late-1980s FWD General Motors pieceashit common as dirt
four-door mid-size sedan of some kind, with big tires (A Q-ship, if anyone
remembers what that was). He PASSED me whilst I was cruising at 90 (I
slowed to let him by -- I figgered that anyone who could catch up to me was
either the police, a drunk, or somebody cruising faster, and discretion is
the better part of valor). I fell in behind, used him as a rabbit and a
radar screen, and we ran along together for 25 miles at 110, with me
hanging on 1/4 mile back. I peeled off at the Cedar Rapids outerbelt, and
watched him continue into the city on I380 at a steady 110. Whew! Not for
me! I dearly wanted to see what he had in that little Q-ship, but I need my
license more.
