RHS,

I'm using SSpdDmon's method of leaving the MAF cal stock. The only method that I know to change the LTFT's in a MAF system is using IFR. There was a considerable change (10%) from factory IFR as an initial hack. With original trim(6%) and timing changes(another 2%), plus 2% to put the trims in the ~-2% range. I have only done preliminary changes, now the real tuning can take place.

I have the first impression that this is a simple and good way to proceed. I also think the VE cal factor can be created by a simple MAF/DYNAIR calc.pid.

To be honest with you, this PCM is very easy to tune. The EFIL system is very good and the forums are full of helpful info. I first thought I'd hate not being able to "real-time" tune. I'm thinking that this method is better, maybe more scientific.
