Hi Tracy, Since you're on your computer this morning, could give a brief summary of what changed in the EC2 code for the latest turbo upgrade? Timing? mixture? Yes, very brief. The ignition timing advance curve for below ambient and boost retard has been refined. Same story for the fuel curve. The MAP table has been spread over a larger range of manifold pressures. Without getting into a boring discussion of software algorithms, that's all I can say. I got my chips today and am wondering what to expect when I install them. Regards, john In view of your past experience, me too! (sorry, couldn't resist). Seriously, there is no specific thing that would be overtly noticeable. If it works, the engine will be easier to tune, there will be subtle improvements in fuel burn and it will be less likely to detonate. This does not mean 'detonation proof ' however. As I mentioned in the note with the chips, The down side is that you will need to start from scratch with auto-tune because the MAP table is now on-board the processor chip rather than in a separate chip as it was before.
