When the ProCharger is finally finished this winter, the 85 LB9 is going to need a tune, desperately, as it is already a fat pig from the factory. Now I've been looking over all the different sites, but is there a bin file for the 85 MAF cars? Or am I going to have to find the wiring harness, computer, and all that fun stuff from an post 86 F-car?

 

I wouldn't waste my time fooling around with the '85 ECM.

Converting to a later '165 or '730 ECM is neither difficult nor expensive, and your '85 wiring harness will work with a few changes.

Mike Davis was kind enough to post all the details.
