There are decel fuel cutoff parameters and also tcc lock/unlock parameters. Does it feel like the torque converter isn't unlocking or engine braking? I have a manual trans so I cant be of much help...

When you turn key off for 10 seconds or so, and turn key back on, the pcm resets the zero throttle position.

The adjustments have definitely calmed your surge problem. Only thing I see that stands out is your IAC counts are still pretty high at idle. I would turn the minimum air screw clockwise until you...

I'll review the logs later and get some ideas. I zero'd out the idle speed correction timing tables. There were also some adjustments to the iac counts vs % airflow table and of course the spark...

Turn the throttle stop screw clockwise another 1/2 turn. Try this bin after pulling power to PCM for 10 seconds or so to clear all of the learned values. Warm the engine up and do a short datalog...

I'll view your bin and datalog this evening. I got called out to work yesterday eve and didn't get home until about 7:00 am this morning. I will make some adjustments to your bin and you can try them...

Don't think you have a vacuum leak. Something is commanding the egr on and it seems like you have it disabled by scalars. I did a bin compare between your bin and BJYL and found several differences...

Your datalogged spark doesn't match what is in the bin file. I have been trying to find what is causing the commanded spark advance to be lower than what is in the tables. Most places I checked it...

Twist throttle screw clockwise 1/4 turn. Look at IAC counts. Adjust only when hot. Keep turning clockwise until counts drop to around 10 or a little below in park. Shut off engine for approx 10...

I have came in late in the game obviously. If you have 80lb injectors and running them at 20psi, you have approximately 100lb per injector and you may have a little too much injector. You can try to...

I just reviewed your idle log file and the idle timing is fluctuating a lot. The PCM uses timing to make fast idle changes instead of trying step the slower IAC valve. Can you post your bin? First...

I have been band-aiding the same issue for a while. There are proportional gain settings for the O2 at idle which can calm the idle surge down. Lower the proportional gain settings under O2 PID Idle...
