I understand that there's an added dimension to irgnition timming with the advent of VVT and I'm still learning that. But anything else I do; be it the slightest thing like raise the speed limiting govorner I'll get the SES light, flash it back to the original tune and no SES. Can anyone shed some light on the Gen IV engine tuning.....................
thanks
