anyone out there have a bin for a 1990 corvette(with auto tranny)as i would like to compare it to my 1990 ta bin and see what changes were made if any to help the corvette be top dog--i am assuming that timing values have changed to compensate for the aluminum heads

p.s i'd like to see any year bin that use speed density.
thanks
pete

I have quite a few bins at the "bin archive" I have on my server. There's quite a few SD bins. For F-Bodies I've noticed that from 90 to 92 they are 99% the same. It's at http://www.truspeed.org/bins.html

thanks blade it's a great site and i hope to contribute to it soon as i have a slp,and a hypertech chip that i should be able to read soon.i have already downloaded a couple from your site but was told that corvettes with their aluminum heads used different spark tables and wonder if this is true?i assume so because of their better cooling capacity.
and i assume with my afr heads that the corvette bin is the one to start with in the search for perfection.

thanks

Universally the AUJP is the best of the SD codes to start with for an auto.
The differences will become real obvious as you start. You'll generally want more in the cruise areas and less at WOT.
As I recall the Y bod 730 even thou 8D has a few items that don't line up, and you might be starting off on the wrong foot relying too much on that. The vette heads were only 56ish chambers and that has alot to do with the burn process.
One of the big issues is being able to measure performance, and accurately figure out what the engine wants.
