Procede hesitation at WOT
I remember a few members having this issue but cant find any of the threads now.
I'm running with full bolt ons including meth. Issue seems to be the car hesitates going into high rpm's. Car launches fine and climbs through the rpm range fine and then around 5500-6000rpm, it seems like i dropped an anchor and the is drag, car makes it up to 6800rpm and changes gear (Auto) and car launches again. Can see any codes and low rpm all is well. Only when i wind out the gears i get this issue. Ideas? Plugs are about 6months old and i'm running 90%meth mix. Temps here are pretty cool. I reset the adaptations and still having this issue. |

Hey, hope things are going well. Change your mind about Shift S3ctor?
Do you have any logs you can post? What firmware, map are you running? |

I was trying to do logs yesterday but roads are wet and I keep breaking traction so not getting a decent run in. Will have to wait till it dries up outside. I'm running rev 3 with may maps I believe. It's the one before the sept maps. |

Wish you could make it. It's going to be a good time.
I have a rev 3 also. Just upgraded a few months ago when I got the flex kit and flash. I'll be getting a new flash in a few weeks and a little dyno time before Shift S3ctor. Should be putting down some good numbers. Torque is off the charts. I don't drive the car too hard around home, but the more torque the better as I look to put a few car lengths on the other cars so they can try to play catch up. Anyway, when you get a few hours of dry, shoot me some logs and I can dig through them and try to help. Also attach a copy of your current map your running so I can look at your boost targets and timing. Your boost or timing could be dropping off... With the newer firmware and maps, my car pulls hard all the way to shift. Not seeing as much drop off up top as I did with older maps that were more conservative. Quote:

I did another reset with my BT tool and filled up in the USA at texaco 92oct. No more stumbling! Chevron 94oct in Canada is plain shit!!
Ran into a buddy with a gtr and he said the same thing. They improvise by buying gas up here( 92 or 94 octane) and then add 4 gals of pure ethanol. I'll keep monitoring! |
