First time I've actually pulled logs since going to to Stage2+FMIC running roughly 94 octane (blend of E85 and 91). Pulled the standard 3rd gear log as well as a 60-130 log just for kicks. Still getting the hang of datalogging with the Cobb V2. Very different from the OFT.

3rd gear pull:

60-130 pull:
http://datazap.me/u/alpineswift/60-1...=0&data=1-2-21

Every map on the Cobb has just felt rock solid compared to the OFT maps. I have noticed the boost isn't as high as it was when I was running the stock DP's (17.5psi vs 16.5-15.5psi) but my dyno this past saturday @ 391awhp and 441tq seems to prove that my car is still a beast regardless of the lower boost pressure. I think a lot of it has to do with the altitude up here. The turbos are breathing a lot easier into the ar catless dp's but they aren't really getting any extra air on the induction side either.

Based on the logs, I don't really see anything that would cause concern. No knock correction and a healthy AFR seems like a win win in my book. If anyone notices something that doesn't look right, please let me know.

why'd you ditch OFT?

Lack of vendor support, lack of tuning support for future single turbo application, off the shelf maps left a lot to be desired, and slow write speeds.

Timing curve looks excellent and fuel is fine. Actually that timing curve is outstanding, the ethanol really helps there.

You’re overshooting pretty good on spool, which doesn’t surprise me. It’s going to be a challenge getting boost really dialed in at your altitude. If you could add TPS that would be helpful to see how the throttle plate is trimming boost once you overshoot.

Maybe try pulling out a bit from the adder table down low?

Logs look very good, however I doubt seriously you are putting down 391 awhp and 441tq ?

Actual load is between 150-160
Timing is 9° timing @ 6k RPMs
Boost is 16 tappered to 11 psi @ 6k rpms

I would say this looks closer 391 "crank" HP not awhp or whp, or the dynoe is readying wayy too high

I don't detect any TC in WOT or at post shift. Usually if there is significant TC it would reflect in his boost means.

His actual load, boost means, and boost are not disruptive in the curves

Check the dyno chart compilation thread. The numbers pulled were on a dynojet corrected for altitude. The torque could be off but the horsepower is accurate for what the car should be putting down out at sea level. Uncorrected it put down 309awhp and 349tq. (That chart is under my corrected chart).

Agreed, I don’t see the chop and noise you’d expect if the throttle was trimming boost.

Either way he needs to work on the overshoot. Outside of that, it’s a very sharp log.
