Re: Commanded AFR not matching AFR tables in tune

-setting “knocking” and “overload” AFR tables to the same values This is one of the reasons why the Cobb OTS tunes blow up stock engines making less power than the stock tune. Don't do that. -I can set “min desired lambda/afr” to .782 but then the ECU looses the ability to richen the mixture in the...

Re: WOT fuel cut at ~5000 RPM

Is there a "rule of thumb" we can use as a starting point? And what should we look for if we were to deviate from that value (just read plugs? Or is there more we can look at from the data logs?)? The "rule of thumb" or the point of reference is the factory tune. As we know that...

Re: WOT fuel cut at ~5000 RPM

The target WOT AFR depends on the fuel used, its ethanol and other bio-fuels content, as well as on target boost, maximum air flow, and so on. 95-98% IDC may be still safe. Usually once you go above 90% you need to inspect the sparkplugs from time to time to make sure all the cylinders burn right an...

Re: Accelerator Pedal Position

That looks about right for a stock gen2, that's how the pedal position sensor is calibrated.
If everything looks fine on that log you can go with the high load no problem. PM me if you want to go custom.

What adapter cable are you using? Did you install the drivers for that adapter?

The defect is still there, you just got lucky getting the fuel trims below the threshold above which the ECU does not learn.

Re: LTFT stays at 0 no matter of what

Post a log.
If the STFTs are lower than -20 or higher than 20 then the LTFTs won't learn.
