i tried a search but i can't find a XDF file for tunerpro for a 3.1 V6 in my 91 RS. I'm also unsure as to whether the .bin that i got is correct (AZTX) from efitune. i know the car uses the 730 ecm, and i have the right datastream .ads file from the tunerpro website for the RT version. Does anyone have the right XDF, or can you verify that i have the right BCC?
the 730.ecu file that i have is for the V-8's tho, the $8D mask. I tried using that via the import option, but it doesn't work with the V-6 bin. The values are all waaay off. where can i get the correct .ecu file for the V-6? $A1 according to one of the posts that turned up in a search.
thnks for the link. I d/l A1.zip, but it contains two files labled 727_730_A1.doc and ARUR_A1.txt. am i supposed to change one of the file extentions to .ecu?

The maskid in your 3.1 is $88. The AZTX bin _may_ have been superseded with AZTY (auto car?). AZTY is the latest and greatest bin from GM. The ECU file for it will be ATTA???(something). Can find that and a hac for $88 over on diy-efi.org.
At a minimum I would start with a stock bin and tune/change from there.
it's called 730_atta.ecu in the uploads folder. I think that's where i eventually found it. It's rather incomplete however, as there are several "mystery" tables, and the units for some values are skewed. The important big stuff tho, spark and VE are there.
