Subject: 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! :)

Subject: Team3S: 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

Admin part: I got HTML in Matts message. Please turn the stuff off please.

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 getting
> the ARC 2 up and running.

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.

From: Sam_Wong@hyperdream.com
Subject: 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:

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.

Subject: Team3S: Safe Boost?

What is the max boost you can SAFELY run on stock ingectors, fuel map, etc? I
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 Drop In and 3" Cat Back
exhaust (no mufflers). I will get a boost controller when I upgrade the turbos.


Thanks!

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!
