Im having a problem where if im under 2000 rpm's in any gear(usually 2-6) under slight acceleration im getting "bucking". Im constantly having to downshift my m6 to avoid this bucking. Is this a timing issue?

Ricardo

I was only able to get rid of the problem by switching over to open loop.
It got even better after changing the injector offsets to the appropiate ones.
It made an unbelievable difference in driveability.

Ricardo, de que tamanio son tus injectors? Are you using lt1 edit or tuner cat?

Ricardo

I´m using Accel 30# Injectors.
I know there have been a lot of posts regarding them, but mine do not leak and work just fine in open loop.
I do my tuning with LT1 edit.
A wideband is strictly necessary for a good open loop tune.

Im running 40lb SVO's. I have lt1 edit, and I have a wideband in the car. Is it possible to send me your file, so I can take a look, and get some hints? Deenasty83@comcast.net
