Ok,
So for the past year I keep seeing more and more tunes from other shops where the tuner is zeroing out everything under the
Airflow--->Dynamic----->
Prediction Coefficients: Base, Current, Old, Corrected, Cam Transient, MAP, MAP Old1, MAP Old 2, TPS, TPS Old1 and TPS Old2
I found some information where people say to zero them out on cam cars and others that say not too. I'm hoping people can post their reasons and thought process behind their approach.
Also, I keep running into tunes where tuners disable LTFT and solely rely on STFT to make any fuel trim adjustment once in CL. Again, I'm looking to understand why tuners do what they do.
Thanks in advance.
