Ok progress is slow but better than nothing!
Set all the DI tables to zero and put in ztans updated front O2 scale data.
Installed wideband in front pipe before cat, watching the display, the AFR values are close enough to the factory sensor so I'm confident it is not faulty.
Logs were too big for datazap so in the attached zip file.
Same POL table used in each case as only MAF scale was altered each time.
Filename: 800... Original ROM log and MAF scale for VGI's utility.
Went for a drive, mostly highway in 5th or 6th gear with cruise control set to ~100km/h then plugged the log (filename: 800) into VGI's tool to generate a new MAF scale for the next attempt.
Filename: 801...
This is the log after flashing the new MAF scale from previous data review. Same road but shorter.
This log showed the LTFT improve out of sight so thought I was on the right track. But plugging the data into the VGI tool said to make further changes, in some case by as much as 20% looking at the comparison feature. I did not use smoothing.
Filename: 802...
Log after next flash. Now the LTFT's are not so nice half way through the log. The car also had some noticeable hesitation at first throttle application and stalled on me once at the lights trying to take off.
So I am assuming I've gone in the wrong direction here? Thinking of returning to 801 scale and doing a lot more logging. Any pointers or comments before I keep going?
