suggestion for these OTS maps ... perhaps you can adjust the scalar upwards a bit to keep the trims from being so close to tapped? easy enough to do in TunerPro.

These graphs continue to bemuse me, but it looks fine outside of some minor timing retards. Likely due to IAT comp tables, look at your charge temps by the end of the pull. You need a better intercooler! Delta of almost 100 degrees in terms of charge temp after a 2 gear pull, not what you want. Boost curves, AFR, etc look just fine to me. Maybe a bit tight on trim? I’m sure PROcede folks will chime in, it takes me a few minutes just to figure out what the hell I’m looking at with the graph style data logs.
Why do PROcede logs do so much better with AFR than JB logs? Don’t mean to derail this or start a tuner war, but 80% of the JB logs I see are running quite lean. It’s a DI motor and JB is proven, so I’m not saying it’s unsafe…but it does strike me as odd when AFRs are 14 at peak boost.

Seeing low timing and timing drops. Ait is super high. I bet if you could log all cylinders you would see timing drops all over the place. Fuel trims are high too. IMO, trims should be in the +- 10 % range to leave some headroom. Overall not too impressed. You need a fmic like yesterday.

Charge temps are through the roof, and the car is very likely pulling back timing as a result. Whether that solves all the “noise” is tough to know, esp. since your log doesn’t show all 6 cylinder corrections. But to be clear, your car is not enjoying those types of CATs.

45 degree increase from beginning to end of a 2-3 pull is probably pretty standard for the stock FMIC in hot conditions. My IAT's climbed from 117 to 148 during a 1/4 mile pull in 85 degree, humid, Florida weather with my 5" ETS FMIC.

Does that mean you logged a WOT pull in 2nd from 2,300ish to 6,500ish? |

His in-gear fuel trims trims peak at 22%. And at redline. Not really what I would consider close to maxed out. But I agree that an intercooler certainly would help. But I think that applies to anyone with a stock FMIC who isn't driving in Alaska

I don't understand why you are so against having trims closer to 0. it allows the DME more adjustment range on both ends of the spectrum. FWIW, I like to keep my trims around +10 midrange down to 0 at redline. |

After extensive logging I feel all tunes are quite aggressive. It's either that or maybe I am too conservative Harry |
