Funny you say that. I knew that in the documentation JB4 lists messing with 11/12 will cause strange oscillation issues. I changed them yesterday, and didn't seem to have much effect.
This morning, driving in though, it seemed to be a lot more calm. It could be due to air temps being in the 40s though and the engine/oil taking longer to warm. Once back at 225F or so, the good old stutter seemed to return.
@Chris I can even notice it when accelerating in first and second gear, that it is jerking while accelerating. I tried logging steady throttle, but JB4 wouldn't show anything. I know there is a setting somewhere to log when its not WOT, but couldn't find it at stop lights
I'll post my datazaps from this mornings quick pulls to see if it gives any small indication of anything that could be adjusted.
