yep just saw that iam looks pretty ordinary if he is running correct fuel for tune.

side issue do you know the parameters the ecu uses to determine the base timing b to a switching or transition.

i know it runs base b plus knock correction max a when iam is 1

so at what point does the transition occurr to base a plus i assume knock correction max a to determine overall base timing plus offsets due temp iat ect ?
