See the attached MegaLogView .jpg for an example. Also note how spiky the coolant temperature is. I think I will check ...

It seems that my acceleration enrichment triggers almost randomly. I can be cruising along at 2500 rpm, constant throttle, constant MAP and the acceleration enrichment will trigger causing the engine to stutter. Can't tune and engine like that!

It is at its worst at 2500 rpm, but will trigger at ...
