Data logging gurus, need your help reading log.
After a crappy night at the track i felt the need to see whats going on. So i data logged a run in 4th gear (This is 4th gear with a US STI transmission). Can anyone tell me what is going on and why I am not hitting full boost. Test was with 71 degree outside temp.

What do your boost targets and wastegate duty cycle targets look like the 100% columns? Your wastegate duty cycles are increasing towards redline as your boost is falling off. There could be a couple of reasons for this. I'm curious to see what your map looks like first.
Also, your car appears to be pulling timing in a few places (at 4200 rpm and then at 5000 as wrxblubayou said). It would be good to smooth out your timing curve a bit so that it's non-decreasing once you hit peak load. Are you running on 91 octane gas? Thanks, Mike |
