I really think the timing is making the car buck. It must be pretty obvious that if timing is too advanced (don't know for sure if mine is or not) it would cause the motor to buck. I sent you an email with my latest data log. Thanks for taking a look at it, I have spent hours looking at these things!
Hi Tom,
Sorry it took so long to get to look at your logs - 3 very busy weekends in a row.
Anyhow, This afternoon I correlated the datalog and tune that you sent, and as far as I can see Datamaster is reporting a spark advance greater than requested by the tune. It's not far off - most of the time it's showing between 1 and 5 degrees higher. I scanned the other tables (for example temperature correction) and cant see a good reason for it. I'm going to try scanning the forums and asking a couple of folks to see if there's a good reason for it. I'm going to take a look later to see if I can see a reason for the surging problem.
