If I come off the throttle or use engine braking etc and my AFRs go to max lean (22.5), when coming back in with the throttle unless I bring it in rather slowly, Its quite jerky as the AFRs come back down to normal. I.e if you were drifting and were on and off the throttle to maintain a drift, going from overrun straight to full throttle etc then it would be impossible to do due to the jerky nature.

Is this just that my acceleration enrichments need to be tuned? And is this actually possible to get to a good tune as I only have a MAP sensor and no TPS?

Thanks

yes, tune your MAPdot values, sounds like you need more fuel on slight throttle changes.

sit at idle and jab your throttle at different rates (you can see what value you are hitting with teh red line) add PW until it starts going slightly rich with throttle change.
