Strange behaviour M4.1 after chip-tuning

Post by 75 GTA »

I just can´t find the answer for a problem that I have with my TS.

I turns out that after chipping it some strange thing began to happen...

The rev limiter has been raised some 500rpm´s (6750 -> 7250) but the strange thing is that the rev cuts earlier on 4th and 5th gear...around 6750rpm! :shock:

To complicate things...I just noticed that going down a hill the 4th and 5 th gear will hit the rev limiter later...around 7250, like it supposed to be on a flat road.

Is there a parameter on the Motronic that actuates on the rev limiter depending on power load?

Check all your ignition parts for bad connection, sounds like your ignition doesn't really manage to ignite properly -> misfire.
