In the process of getting an e-tune, but i need to log a few things for the tuner. I have tried a lot of stuff and googled search but i can't seem to figure out why my LTFT and STFT parameters always log as zero. I did see where cobb has issues logging neg values with those, but does that mean that my values are all neg??? Also, i saw ATR is a fix...but curious how ATR works...do i need to have my laptop connected to my AP and my AP to the car??? Also if i want to log AFR's do i just plug my serial port into my laptop? Any help would be appreciated. Trying to get my tuner this info so he can finish my tune.
