The KC numbers are dependent on the tune- just because they aren't at 10, doesn't mean there is a problem. I would look at the overall ignition timing curve to see how it looks. If your car is pulling timing for some reason, the retarded ignition might be the cuase of your high egts. What kind of temps are you seeing?

Way off base on both of these. IAM goes to initial value after a reset. If there is no knock the IAM advances from 8 to 12 to 14 and finally to 16 on a stock tune. With Cobb's initial value being at 12 the advance goes to 14 and 16 after only a few miles. The only time the IAM drops is if there was knock with the level of KC in the KC maps that the IAM references... if the IAM stays low and steady then the ECU has found the safe KC values to run without causing any knock. If the IAM was to go higher different KC values would be referenced and run... hence the low KC value number on a low IAM and high (10) on an IAM of 16. That's what KC values are based on... Some tuners mod the KC value tables, some don't. The good ones do and know what they are doing to find that sweet spot in the the timing curves.

Telling someone that if their curves are good even with crappy KC values and low IAM is not good advice. IAM should always be maxed at 16 with a proper tune.

pottymouth, go to the Tari forum and read my post. It'll steer you in the right direction.
