Hey guys.. I have an 89 Formula that HAD a 305 TBI. It went south and i put in a stock 92 Chevy truck 350. I swapped on the 350 knock sensor and the Whole tb/injectors...BUT what about the chip?
Will the factory truck chip snap right into my Formula's computer and work just fine ..or what? Are they compatible at all? How about the Caprice "police" chip? Part numbers would be helpful too!!

 

Hummm, I have no clue at all, I might suggest talking with the PROM people, they know everything

These are your options as I see them.

Call a dealer and get a EPROM from a 89-90 Caprice. These were the only years when the Caprice used the same ECM (1228746) as your Formula.

The other option is to swap the truck ECM (1227747) and EPROM in place of your current ECM. It will plug right in and run.
