Awesome, I will try this. Thanks for the info, I figured there was a combo of channels I needed but didnt know how to figure out what was required.

I have a 2007 c6z06 with an e38. I am having trouble logging injector duty cycle percentage. I have the inj duty cycle parameter in my charts, but I can't find it anywhere to add in my channels list...

10-4. That makes sense. I think I'll log it to see if thats the cause. I think alot of the timing pull is right when I press the gas pedal.

Well they don"t seem to go back to zero, though ltft are alot closer to zero when I'm on th gas accelerating. Though for steady state or low load stuff they are around -10. I don't understand, I'm...

I tuned my car first by doing the VVE tables with AFR Err, then MAf with AFR Err. After all that I copied and pasted the values for my maf high and low and VVE tables to my base tune. I enabled...
