But this issue has apparently been present before the mods and stated its just became a annoyance
The car when it shifts from 1st to 2nd will bog down incredibly and fall flat on its face. Almost like it?s lost all power. The rpms will drop to 1500ish and then it picks up and drives normal. The issue happens on the 1-2 shift in sport/track/drag. Doesn?t happen in normal because of the 1-3 skip. Seems to be related to lower pedal inputs < 20 percent and slower speeds related to normal driving, taking off from a dead stop. The crazy part is it?s completely random, and impossible to recreate on demand, the once or twice I?ve managed to actually catch it on a log, what I was logging I do t think is what I need to be logging. I?ve tried to dig out those logs with little avail since I?ve been trying to recreate it more reliably they?ve just been lost. From what I saw here are some cliff notes.
Throttle and pedal are constant and throttle doesn?t close
No errors shown
Only thing I?ve managed to catch is spark plummet then come up.
The source says trans shift and one other says torque control.
So my initial question is ideas on what to log?
So I can go out and get one and then maybe diag it better.
Thanks as always everyone.
