Is there a way to control the overshoot for the STFT on the E67. I am tuning a ZR1 that is "hesitating" and it's due to the overshoot. You can see in the wideband that it oscillates between 14 and 16 in the overshoot while cruising at a constant speed and rpm in closed loop. This is very annoying and I wish to solve this. Anyone know how to do this?
On the LS1 PCM i could change the airflow modes at least and that gave me a way to change the overshoot, although we do have access to the multipliers for this.
Is this a problem with the close loop algorithm or a problem in my tune perse?
Anything I should look at to avoid this hesitation?
Funny thing with bigger cams and the ls7 (maybe because it's a bigger engine) I don't get this issue. The overshoot has very little effect on the engine's stability.
