Log check Map6 with ecu tune

[GTCHAN]

Hi. This is with 91 octane and E30 mix. Lap3 ecu 1.5 on map6. Which one has the best log? The ecu tune or the one with map6?

Compairing them back to back, hands down the JB. Change my mind...

The Lap tune is off when it comes to fueling. At E37, your HPFP dropped to 5, I have no idea how that car didn't go into limp mode. Your trims are maxed out which means Tip In Lean and that car is starving for fuel. It did have more boost, but timing only hit 15ish deg advanced.

The JB log is less aggressive, but trims dropped nice which means it's getting all the fuel it needs. Overall timing hit around 19 deg advance, and HPFP stays at 10 which is where it should be.

Thanks for the explanation. Yeah, map0, the car didn’t go on limp mode and it just wants to pull and pull. I guess it’s really an octane issue when you want to run more boost and you have only 91 available. Staying on map6 for now. Thanks again!
