I'm going to run an LT1 intake and will need a new starting point as far as a bin is concerned since the '86 TPI I'm running now has the CSI still installed and functioning. Since the CSI won't transfer over, I think the easiest starting point will be an '89 MAF TPI bin. Are there any particular bins to stay away from in the '89 pile? I'll be downloading some from diy-efi today to mess around with tomorrow.

Also, side question: The CSI will be fine running the '89 bin with the current TPI set up to get me close, correct? As long as the CSI isn't leaking anyway...

 

Run an ARAP bin and unplug the CSI

 

The only ARAP bin I can find is a vette, but no coresponding ECU file to go with it. Searching this site has helped me understand what I'm going to need to do with the CSI (dumpster), but I don't want to start with a bin for a 350 6 speed vette unless it's a last ditch effort! LOL! Any help finding a 305 TPI bin/ECU from '89 would be appreciated. Also, what's the code for the '89 ECU file?

 

ARAP is $6E.

you can downlaod ANZA from my site (as well as the 6Ev010.ecu file) from my web site. ANZA is the stock bin from my '89 (MAF) 5.0 M5 Trans Am.

Any hints on what all is different from M5 to AT? I know the spark table is a bit different... outside of that, I'll be writing notes I guess...

On a side note, I added a bit of crank fuel and cold fuel to my modified factory bin and disconnected the CSI. It works for now anyway, but I have yet to make a cold start below 80 degrees or so in the two days I've had it in the car. We'll see. Thanks for the help finding the files!

 

oops, you have a auto - they're right then, start with ARAP (using 6Ev010.ecu to edit).
