Hey everyone, I'm new to burning chips, and trying to get into doing it. I have an AutoProm, TunerCat RT, and RTTunerPro. I've hooked it up trying to do real time tuning to my car, and every time it runs like ****, and sets off the check engine light. I'm having a very hard time finding the right stock BIN for the 305 TPI and 700 R4 that came in the '91 GTA's, and not sure which one is right for the job. Any ideas, links, advice would be very appreciated, as I'm not finding much concrete info on the 305 TPI, in regards to BIN's, and chip burning. BTW, I'm stuck with Vista, if that makes any difference.

 

i don't know for sure what Bcc you need, but it looks like AXXF is the latest up date for a 91~92 305 TPI auto trans

you can also look here for other Bcc's,

you can find some bins here,
http://www.moates.net/info_pages.php?pages_id=14
open the link on that page in a new window & then copy & paste the user name &
pass word to access the FTP sit.
also, you can find some here,

just a thought here, you may want to have a look at S_AUJP_V4. its for a 350, but you should be able to make the changes to match your 305.

sorry about the Vista thing, nothing i can do to help you there, LOL
