The problem still occurs with TC turned off. It's a heads/cam motor, but only a small cam, 220/224. It's done this since the cam was installed. I will try turning spark smoothing off and see what...

I've finally had enough with my car shaking back and forth when I'm trying to drive it around at low revs in the city. I'll be going along fine then all the sudden the engine will begin to shudder...

foff, do you have any idea what's going on here?

I took another scan this afternoon. I noticed that something is changing the timing I put in, and the max timing the computer is allowing is 50 degrees, even though I have cells that go beyond that....

But is that table really adding timing in degrees? If I put in 40 at 4800/.52, is that 40 degrees of timing I added? If it is, how did I never get any knock? I"m only running pump 93 octane, it's not...

Here's a setup and scan where I only had 40 units of timing at WOT.

I went to the drag strip today and tried to do some KR tuning. I kept increasing my spark advance mor and more and more and nothing ever happened. It got to the point where on the high and low octane...

Figured it out. It was something I did in the tranny settings, went back to stock and it works fine.

I know where you can get a 97 bin of the same thing. Should be identical.

Ok I just checked it again. It has nothing to do with closed loop. Within 20 seconds of starting the engine this happens, whether I'm moving or not. Guessing it's something with transmission but I...

My 1992 Grand Prix with 3.4 and stick that I converted to OBD II is now running. For some reason, when it goes into closed loop, it doesn't want to run over 2000 RPM. It will, but I have to goose it...

I have talked with Loyde at FastFieros and he has given me some helpful tips. Hopefully they will take care of everything I need, but the real test will come once the motor is running.

This couldn't be more confusing! So now you have single vehicle licenses, and model/year licenses? So single vehicle licenses can only work on one car of one model/year, but model/year licenses can...

OK, well what if there wasn't a manual ever for the car? A 97 Monte Carlo never had a manual, but from my experience with other software it can't be impossible. I see guys doing L67 swaps with...

Because unless I'm just not looking in the right place, there is no way to simply turn all the transmission controls off in VCM Suite 2.0.xx, and this should be an option. If you're building a car...

So is this how it works around here? If you don't have a V8, F-Body, or supercharged V6, don't bother showing up to the party? It's not like I'm asking complicated questions about my setup. I'm...

Let me start off by saying I am new to tuning for myself. I have a '92 Grand Prix with a 3.4 DOHC V-6 and a 5-speed. I already have it running mid 14s on OBD-I. I got myself an OBD-II harness, a '97...

I too am wondering about this. I'm told in the old 1.7 version of the software there was a place you could go and turn all of the automatic transmission stuff off. I have only had the 2.0 version of...
