Sounds like good stuff to add to the definitions files for my ECUtuner software. I just updated the sample definitions file I posted earlier with a more complete one. If you get a chance, if you could check it for mistakes and add anything good you know that I don't have on it that would be great. It's already complete enough for some heavy duty end user tuning.

Have you seen the per-cylinder timing adjustments? It's at address 8708 in rom 742512 (94 JDM). There are four sets of 6 bytes that get added onto the ignition advnce. The 1st byte for cylinder 1, the 2nd for cylinder 2, the 3rd for cylinder 3 etc. The ECU chooses one of the 4 sets based on some rpm thresholds at 8700 through 8703 and throttle thresholds at 8704-8705.
The adjustments are all zero by default, but you use them to fine tune the spark timing on each cylinder.
