Team3S: 1999 West Coast Gathering Update
Howdy!,
Okay. Sorry
folks. I've been in Florida for the
past couple weeks and haven't done much
of an update
lately for you all.
However, I have made a few changes
to the site
including a new url. Also, added a flyer that you can
download and give to dealerships and other 3S's in
your area.
I
will be making some more updates over this weekend,
including maps of the
area, restaurant information,
and hopefully even sponsors.
Here is
the new url for the gathering: Sept. 24th,
25th and 26th in Monterey, CA
:
http://www.megahits.com/moondin/wcg.htm
Please
send me an email if you will be attending.
Spread the word! It's the
first and only West Coast
Gathering we'll have this century! :)

Re: Questions about a steering problem
Thanks to everyone who replied to
my question about the steering problem.
At least now I have some ideas of
what might be going on and what to look
for. I'm taking the car in to
the dealer for an oil change next week, so
I'll see if I can get them to look
at it for me while I'm there. I'll try
to get some Redline MT-90 in the
transmission too - hopefully that will help
smooth out the
shifting.
Beyond that, I have a few minor dings and scratches in the
paint, and an
Active Aero system that doesn't like to work properly (rear
spoiler goes up
fine but only goes down when it's raining(!), front tends to
stick halfway
when extending and turns on the "Aero" light on the
dash). Once I get all
that fixed I'll be pretty happy with the
condition of the car. Hopefully.
:-)
Thanks,
Chad

The VPC does the same as the ARC ! The only differences are
that the VPC uses a
MAP sensor and the manifold temperature as the reference
while the ARC uses its
own MAF and sensors in it (no MAP sensor at the
ARC2-GP). The ARC uses the air
flow to determin the boost while the VPC uses
boost to see the airflow. Both are
then sending a new frequency signal to the
cars ECU. Due to the boost sensor the
system is NOT converted to speed
density !!

I fully agree with you on driveabilty in
different seasons, cold, hot weather
and so on. But you know that the VPC
removes any flow meter. Therefore saying
that the ARC does not hack/converts
signals also 100% belongs to the VPC. The
GCC as an additional to the VPC and
allows fine tuning on different rpms the
program does not give the full power
needed.
Matt knows definitely more about the VPC stuff than I do but what
he's
describing only belongs to the AFC computers and NOT to the
VPC.
> Not to mention the ease of tuning that is involved in

As the ARC2-GP is the right one
for our cars some signals have already been
prepared for our ECU. Therefore
it should be easier to be tuned in than the VPC
stuff. But it will take about
the same time to tune it in as a VPC to get the
most out of it. For sure I
expect a better driveability due to the real air flow
metering.
The
ARC2-GP is a good thing for sure and it sits at least on the same level
as
the VPC. Some things you said were not really correct about the VPC and
more
belongs to the AFC that is in a totally different region (i.e. low cost
mini
fuel controller for small injectors) The advantage of the ARC is its
ability to
adjust for different weather and climate changes, but some need
this and others
don't. We'll see.
Please note that I want to make sure
that we compare apples with apples.

Team3S: Narrowing down vibration source
I just replaced my driveshaft
with a good used one but it did not help with
the vibration problem that
I've reported for a long time now. The vibration
frequency is the
same.
Symptom: Harmonic driveline vibration felt in the seat.
Seems to be more
noticeable in the rear. Occurs while only in gear,
not in neutral. Occurs
only at around 30mph in 2nd gear, 45mph in 3rd,
and 60mph in 4th. RPM is
usually in the 2500-3000 range.
Vibration goes away when speed is higher or
lower than those indicated at
each gear. Vibration is more noticeable when
applying the gas
pedal.
Note that the vibration disappears when I press the clutch or put
the
shift stick into neutral. Maybe this is a key
point.
Work Done:
1. Replaced driveshaft
carrier bearing
2. Replaced tires
3. Replaced transmission
output shaft and transfercase spool
4. Inspected engine and
transmission mounts (Seems fine)
5. Checked and fixed
wheels
6. 4-Wheel alignment
7. Replace driveshaft
8.
Replace clutch and pressure plate
The next thing I might look at or
replace is the flywheel. Can an out of
balance flywheel cause harmonic
vibrations like this? Anything else?
Could it be something in the
engine or would the fact that it doesn't
vibrate in neutral eliminate this
possibility?
Any help appreciated.
Thanks.
Sam.

In a message dated 99-08-22 03:16:55 EDT,
you write:
<< Symptom: Harmonic driveline vibration felt in the

So if
you leave the car in gear and let the clutch out you still get this
vibration? Lets say you are at about 50mph in 3rd gear - this is just above
your harmonic vibration point in terms of speed. Now depress the clutch
pedal
but keep it in 3rd gear. As the car slows down through the 45mph
harmonic
point do you get a vibration? If no, then this tells you the
vibration is
associated with the engine - I'd really think about replacing
the engine
mounts.
One other thing you really should check: make sure
all the heat shields
around the exhaust are not loose. I had a Toyota Supra
that gave the same
kind of harmonic vibration you describe - it would happen
at a certain engine
rpm for each gear. It has been awhile but I think it
only did this while in
gear. It was certainly more noticeable when
accelerating. I do remember
asking my local mechanic to check it out and
telling him I was almost
positive the problem was in the drivetrain since
the vibration was so bad. He
found a heat shield that was loose and secured
it - problem solved.
It is amazing how much a thin piece of sheet metal
will vibrate. Perhaps it
was mounted just beside an attachment point for the
driveshaft. This would
allow the natural vibration from the engine to travel
down the driveshaft and
excite the heat shield. check it out and let us know
what you find.

What is the max boost you can SAFELY run on stock ingectors, fuel

am considering upgraded turbos and need to know how far I can go
without messing
with too much else. Only current mods on the car is K&N

when I upgrade the turbos.

BTW. I am looking to buy an 'economy' car for my move to
California... my VR-4
isn't exactly fuel efficient and since it has low miles
I want to keep it that
way. So, I was looking at V6 Camry's yesterday and
realized how spoiled I really
am! It is really hard to get excited about a
car that isn't at least 300hp!
If anyone has been through this delima
and gotten a fuel efficient (and somewhat
powerful) daily driver please
e-mail me privately and let me know what you use...
Thanks
again!

Rich-
I haven't raced for some time, but I think you need to know
that
when you put more cornering torque into your rear end, you
will
reduce understeer or "push." Therefore, stiffining your rear
roll stabilizer bar, or increasing your rear tire pressures will tend
to
mitigate understeer, or "pushing." Try it, you'll like it!
