Default 1989 ecu

I have been asked for a friend to look into tuning his 1989 Corvette. It is currently in storage so a bit troublesome to get to so I was going to find the base tune and files to begin looking over the parts we should adjust. Can any one give me the ECU used in a 1989 automatic car? Online searches are returning some strange results. Thanks in advance

Thank you. All I was finding pointed me to the $32B and holy hell that is lacking for an ECU

6E is correct and it has enough fleixbiity to allow you to tune some pretty wild combinations.

PM me with your email. I have the 6E bin that's probably the best starting point for an 89 auto. In 2010 I searched for (and downloaded) 89 "stock bins". At the time Moates had a support forum (which appears discontinued). They used to have lots of bins (which is where I think I got the 89 auto bin). I would be happy to send you the bin I have. (I figured out it was meant for an auto by the transmission flag and constants). FYI: It is called 89vet 6E.bin

For anyone else reading this, I only downloaded 89 bins. Back in 2010-2011, I narrowed "stock 89 bins" down to down to two....one for autos...and one for sticks. FYI....The automatic bin also has values coded for transmission operation. The stick version is zeroed
