Wayne -- So as I understand the 2.0 "self tuning" upgrade --- it will NOT self tune -- it really should be described as "self healing". In other words IF the tune up is close - the ECU is capable of filling in the blanks or adjusting a VE table using the surrounding cell info and the feedback from the O2.

I was thinking - and the advertising led one to believe - that this was a "self tuning upgrade" and would be capable of self tuning ala the EZ EFI. It will not.

When I asked them they said it will get you going but still needed to be tuned, its not like the EZ. We'll see! There still may be a switch in my future.
