Pulling Timing

Segments · 11-18-2017, 07:27 PM

Hey guys, I have a 6266 N54, PI with full e85. I've noticed that the car pulls heavy timing, across all sorts of boost. I'm on BL coils with N20 plugs gapped at .026. I have a 7.5" VRSF FMIC, and run full e85 thats usually in the E79-E81 range. I'm unsure as to where to look to next. I know I'm on that batch of Index 12's that are technically S63 injectors and not N54s, but nobody ever mentioned an issue with them. Going to tag a bunch of logs; I'm desperate at this point and cant seem to get an answer.

3 Pulls at 26 PSI

Looks like throttle closure also ... and wgdc looks wrong? (17psi)

Spool mode needs work. If you look at wgdc after pid and stft 1 you'll see the correlation. STFT's should be close to +/- 10%. The max it'll adjust is 30% and you really never want to be that close.

Looks like you should talk with Twisted Tuning and get a revision done. IMO
