Fine Tuning Low RPM crusing in a high gear on a cammed LS7.

[JASON11WS6]

Hey Gang, tuning in a C6Z after a stage 3 cam. Car runs great but in a higher gear and under 1500 rpms the car bucks like crazy while off the throttle. The cam is big but not practical joke big and I've never had these issues before. Same cam, same car and it didn't buck like this.

I tried to add timing to the idle table base and coasting and it seemed to make the idle hang coming to a stop. The timing seems to be dropping below what the table is set at. Both idle and cruising seem to have this issue. I'd hate to mess with the minimum tables over this. JASONBOYLE.C6Z.007.hptJASON.BOYLE.C6Z06.007.hpl

Looks like spark smoothing to me is still enabled.

^^^ Yep. Like Alvin said, flip that switch.

Nice catch. Thank you, that's gotta be it
