Default Re: LT5 ECM Tuning thread

Picking this thread back up, using a question asked on the list...

No idea about the cam timing. I have a Daytona 24hr calibration from Jan-93. I am sure it is not the same as the BW cars, because it was intended for racing, not passing 50-state smog.

The bin I have is based on a '90 (AUAH) calibration. Surprisingly, the changes are fairly minimal, compared to what one would suspect for a race engine. The SA table has few changes, mainly at WOT. About 28d total advance.

The VE tables are largely unchanged, except the high RPM table w/ SPT's open, no doubt where the car spent most of its lap. It is also clear that the race car had no Port throttles, O2 feedback, or knock feedback... not unlike the Snakeskinner calibration, in that regard.

Just trying to keep this thread alive ...
