Russ, Curt, et al;

Remember the Shelby Mustangs  of 65 through 68  (69 was a Ford buy-out that
used Shelby's name)....well after they became affordable on the used car
market in the 2nd and 3rd owner circuit, most had been slam dunked.  They
disappeared into junk yards and were recycled as early Hondas, Datsuns and
Toyotas ;-(   Hardly any of those  Shelby beauties remain. Those which do,
are the result of  owners who expressed:

> I thank you but it wont be luck it will be persistency and borderline
> physcosis that will get me to where I want to be.

Similarly,

>so consider getting the proper instrumentation before going far >enough
where you need fuel control.

This kind of distilled and humble advise, will insure enough of the 3s's
survive for  admirer's of the future to appreciate. Too many have already
seen hard lives. Many more are already becoming Toyotas and Hondas.  I think
you guys likely mumble wisdom into your morning  coffee ;-))

Roger,

Has anyone on the list even discussed this important find from one of the 3s
members?
Accel coils (motorcycle) coils when used to replace our stock coils have
been sucessful in allowing boost over 25psi at stock gap (w/o blowout) with
an ignition amplifier.  I do not see alot of the people on the list actually
participate on www.3si.org  except for a few exceptions.  There is a real
wealth of knowledge to be found after you weed through some of the OT posts
and other garbage.  A lot of trend setters IMHO, and even a couple guys
breaking into the 11s on stock turbos!   A few SLs running superchargers
(real ones like Paxton--not the fake fan things).  Just thought I would
remind the professionals here that there are things to learn from the little
guys that do their own R&D and sometimes come up with great ideas.

Subject: RE: Team3S: HKS VPC or ARC2  continued

After planning out my mods, I have decided to get all of my
instrumentation out of the way first so I see what the car is used to
stock before changing it THEN seeing does. My question is, why dual A/F
Ratio? I have not looked into the AF gauges much, but does it take the
reading from the stock O2 sensors? This is going to wind up being a lot
of gauges if you need 2 AF, 2 EGT, boost, if not more! (fuel pressure,
engine temp) Anyone make a 6 pod A pillar mount?  :(

What about the smaller light gauges like what comes on the ARC II, I
could find room for 2 of those and 3 gauges with the new triple pod
coming out! Can you buy something similar to those? Where? I've been all
over most every place I can think of on the net . . . Extreme has an
interesting A/F and Duty cycle meter. But it says A/F range 12.3 to 16?
Is that enough?

Okay, now here's something I can totally agree with...  I didn't spend
enough time properly tuning my car and the result was a few broken
pistons and damaged heads.  The rebuild costs are currently up to $3400
for parts and machining alone and still incrementing.  The cost for
proper monitoring devices is an additional $500 or so, which if I had
spent that money up-front would've potentially saved my motor (and
allowed me to drive my rather expensive car this summer instead of it
taking up space in the garage).

Things I'd consider the bare minimum for instrumentation:

EGT (preferably dual EGT, with adjustable overtemp alarm)
A/F Ratio (dual or switchable)
Boost (everyone should really have that anyway)
Datalogger w/knock support or an MSD Knock Alert or similar

Using less than that is really dangerous, as I found out.  Everything
seemed okay until the pistons blew apart.

...so consider getting the proper instrumentation before going far
enough where you need fuel control.

It's actually a function of the Mass air sensor to determine fuel cut, not
the knock sensor. The knock sensor only adjusts ignition timing according
to how much knock the engine is experiencing. The signal from the MAS is a
frequency that changes as air flow increases. When it reaches a
predetermined level, the ECU goes into fuel cut. I have no idea what that
freq. is. Some testing would be necassary. There are other signals which
contribute (knock may be one of them) but the MAS is the #1 source.

Different turbos will cause fuel cut at different boost pressures. As we
all know larger turbos flow more air than smaller turbos at the same
compressor rpm/boost.

Dual A/F ratio might help to make sure that your cruising throttle
calibration puts you in closed-loop on both banks.  Its not necessary, but
it might be helpful at some point where the car seems to be running rich on
one bank and not the other (the ECU can trim seperately per bank of 3
cylinders).

For EGT there are some companies that can make you a dual-EGT display guage
in one unit.  Westach can make a dual analog version in the standard gauge
pod size.

I think SPA Technique gauges makes a Boost/Fuel Pressure one which has two
LCD readouts on the same regular sized gauge with peak hold and warning.

That brings you down to 2 "gauges" plus whatever A/F you want to use if you
desire that.

I've got a rattling tranny on my '91 VR4. It is NOT the throwout bearing as I
just had the clutch (and throwout bearing) replaced a year ago and it had no
effect. I put in a stock Mitsu POS throwout bearing and it squeeks worse than
the previous one did. It is a distinct squeeking sound different from the
rattling tranny. The squeeking and rattling appear at different positions as
the clutch pedal is depressed. The car drives beautifully, it is just
annoying at a stoplight if I take my foot off the clutch pedal. Incidentally,
the tranny was installed new in the car about 1996 after synchro failure of
the first tranny.

No, the knock sensor does not adjust anything ! It is a sensor and the ECU does the job.

The airflow signal is not the only signal as the determination of the fuel map value is in funtion with the barometric pressure, rpm, temperature and air flow signal. Not ONLY one signal !

If knock sum is becomming unhealthy high, the ECU initiates fuel cut and sets the ignition and fuel map to the emergency mode. This does allow you to limp home while rpm is limited to 3000rpm. Thsi mode goes away if no more knock is detected and the ignition switched off once. But a code stays set.

Ok then maybe my idea will still work?  I was thinking of using a voltage
clamp (greddy BCC) it allow the signal to pass unmolested until it reaches
the peak you set, at which point it clamps down the voltage and allows
nothing more than your set peak to pass to the ECU.  MKIV's use to prevent
fuel cut b/c they use a MAP sensor to determine fuel cut.

I know this basically I need to find out from someone what the
voltage is that he ECU needs to see from the MAS to engage fuel cut and set
the BCC slightly less than that threshold.

You can't use a "voltage clamp" - you need a "frequency clamp" since the
Karman sensor's output is a frequency pulse output instead of a voltage
output.

See above.  If I remember right, the max frequency from the MAF is something
like 3600hz, but I'd research that rather than taking my word for it.

No,no ! We do not have Supras and fuel cut is on our cars because we do
have smaller injectors than MKIV and fuel cut occurs when the injectors are
way beyond their limit. At 15psi they are maxed out at 100% IDC.. You have
to forget what worked on the JZA80 as our cars are way different !!

If you you do this then you have to save 4000$ for your rebuild ! Please
note that no fuel-cut defencer works on our car as fuel cut is indicating a
lack of fuel or internal problem !

Subject: Re: Team3S: HKS VPC or ARC2  continued

The other reason to run two A/F monitors is for warning. One injector
can go bad (too much or too little fuel)- two A/F meters can tell you
which bank. Similar reason for using two EGT gauges. Just think of
our engine as two 1.5L 3-cylinder engines.

I have the ARC2 controller and both ARM1 A/F meters in the glovebox.
There is still room in the glovebox for CDs, notebook, PocketLOGGER,
and other conveniences. The ARM1 is an excellent A/F meter ($139
direct from SplitSecond). I find the "dial" A/F meters with either a
needle or a light that "spins" back and forth to be annoying and not
that usable (moves way too fast for my old eyes). The ARM1s closely
mimmick what I see on the loggers (well the rear one, which is the
only one logged). They should as they are spliced into the wires at
the ECM from the stock O2 sensors.
http://www.geocities.com/lutransys/jlucius3/j3-2-arm1s.htm

Two EGT guages and the fuel pressure gauge are on the A-Pillar.
Peak-hold-warn boost gauge is on the steering column.
http://www.geocities.com/lutransys/jlucius/2-apillar.htm

EVC IV is in the floor console storage box.
http://www.geocities.com/lutransys/jlucius/2-evc_si.htm

I'm not sure where I'll put the Aquamist WI boxes. I haven't messed
with the three guages in the center of the dash, but that is also a
candidate location for gauges.

As others have suggested, you can get dual gauges in one unit to save

Well, we don't know if there is still some knock around. Also you can
prevent spark blowout by simply using coppers 2 range colder.

Well, the way they work is "let's try" and this not always does it's job
because I go the way first think, then plan, then do, then measure and put
down the results. Their results tend to produce not really correct findings
but it is good to show a direction.

I only said that the MAS was the major contributing signal, and that other

Fuel cut and limp home mode are 2 different things. If you ever experienced
fuel cut, you would know it. It's an absolutely horrible feeling, like
someone planted a bomb in the engine, and is brief. Once the system goes
OUT of fuel cut, the vehicle drives normal again.

Russell, the service manual does NOT tell you what the frequency is. You
will have to hook up an Oscope, or freq. counter to see what the signal
looks like.

REALLY? Or perhaps I misunderstand. Let me re-phrase what you meant
to say: larger turbos will flow more air into the engine than smaller
ones at the same engine RPM and boost level. Correct? How does this
happen?

One correction: fuel cut is initiated by the ECM after comparing
airflow and *RPM*. If it thinks too much air is flowing at a certain
RPM then it cuts fuel. There is not an absolute airflow value nor
boost value. The use of airflow translation devices, like the ARC2
and VPC, reduce the chances for fuel cut when larger than stock
injectors are used becuase the airflow signal is reduced.

Different turbos will cause fuel cut at different boost pressures. As

same compressor rpm/boost.

I highly agree with Jeff. I made a switch for the ARM1 so I can monitor the
one I'm interested in.

The ARM1 is better than I originally thought because it is also the only AF
meter that shows in 0.1V increments but in between adjusts the light level
of the LED in 0.02V steps. Therefore 0.92V is represented by the 1st blue
LED and the second blue dimmed. This works pretty well for me now.

Jeff, what do you mean by Aquamist boxes ? Do you use any gauges for the
water pressure on the water manifold ? I got the "ok" from AutoMeter that
their fuel pressure sensor works well with water as it is stainless steel.

Or do it like Luis Miguel from Spain ... he mounted dual A-pillar mounts on
both side of the dash :) Also the ARM1 is mounted on thw A-pillar.

Fuel cut is initiated too on problems and comes on beforehand the emergency
maps are locked in !

Dont't ask me that and read my pages I wrote some years ago.

Depends on the cause of fuel cut. Seems like you have this experience from
other cars and not only ours. If fuel cut is initiated due to the fuel
value jumped off the map then you should be able to drive normally after
that. But if knock was the problem and fuel cut acted as prevention against
more damage, then your in emergency mode. happend to me 2 out of 7 times.

We drive 3000GT and not Supras or RX7 ... we have to fight against other
enemies and our cars act somewhat different than others ;-)

If our MAS is anything like DSM MAS then max frequency is about
2200-2400 Hz. The loggers only show up to about 1600 Hz, but the MAS
sends higher and ECM reads higher.

Correct, the voltage signal from the MAS is a square wave. Number of
square waves per second is the frequency. Sorry, I don't know if it
is whole or half wave. The DSM Tech Manual or one of the Chrysler
Diagnostic Manuals I have have a picture of this and the voltage
range. Look for a Tech page from me eventualy on our Karman MAS.

You can't use a "voltage clamp" - you need a "frequency clamp" since
the Karman sensor's output is a frequency pulse output instead of a
voltage output.

See above.  If I remember right, the max frequency from the MAF is
something like 3600hz, but I'd research that rather than taking my
word for it.

Yup - put me down for a rattling gearbox in neutral on start up. The noise
goes away when the clutch is depressed. It also goes away when the car warms
up.

I changed trans fluid from regular gear oil to red line MTL and the noise
went entirely away. That was about 100 miles ago. The noise is now coming
back but so far it is significantly less than it was with regular gear oil.
Personally I think it is a throw out bearing problem. The car has 112k on it
with a stock clutch so some clutch bearing problems do not seem unexpected
at this point. The red line made shifting a lot easier and less clunky but
the shifting mechanism does not really allow for fast shifts, nor can it be
described as smooth. It feels like the shifter in my old Chrysler Le Baron.
For a near race car, frankly the trans and the shifter suck. On the plus
side, I love the way my TT AWD corners flat out with no lean,  or yaw. The
power is great, and control is superb. It costs a hell of a lot less than a
Ferrari and is just as much fun to drive.

It should be noted here that a many of the worlds great inventions were made by
armatures that weren't aware that it couldn't be done. While I agree some of the
stuff has been given little thought, it's pretty easy to over analyze an idea and throw
out a perfectly good concept.

I do agree that too many assume that what they did was correct without really
knowing what caused the end result.

I suppose that next you'll be telling me that the perpetual motion machine I
invented is fake  ;-)

The other reason to run two A/F monitors is for warning. One injector
can go bad (too much or too little fuel)- two A/F meters can tell you
which bank. Similar reason for using two EGT gauges. Just think of our
engine as two 1.5L 3-cylinder engines.

I have the ARC2 controller and both ARM1 A/F meters in the glovebox.
There is still room in the glovebox for CDs, notebook, PocketLOGGER, and
other conveniences. The ARM1 is an excellent A/F meter ($139 direct from
SplitSecond). I find the "dial" A/F meters with either a needle or a
light that "spins" back and forth to be annoying and not that usable
(moves way too fast for my old eyes). The ARM1s closely mimmick what I
see on the loggers (well the rear one, which is the only one logged).
They should as they are spliced into the wires at the ECM from the stock
O2 sensors. http://www.geocities.com/lutransys/jlucius3/j3-2-arm1s.htm

Two EGT guages and the fuel pressure gauge are on the A-Pillar.
Peak-hold-warn boost gauge is on the steering column.

Dual A/F ratio might help to make sure that your cruising throttle
calibration puts you in closed-loop on both banks.  Its not necessary,
but it might be helpful at some point where the car seems to be running
rich on one bank and not the other (the ECU can trim seperately per bank
of 3 cylinders). <snip>
