Has anyone attempted to take FAST's complete 4150 throttle body and make it work with a GM OBDI computer system?

I don't see why it couldn't be done. The MAP, TPS, IAC & IAT are all GM sensors, and the fuel injectors look like standard plugs. Seems like a Beretta or Cavalier 4cyl ECM could be used to control it (with the spark tables removed and the fueling tables modified obviously).

I already have two GM OBDI vehicles, and I'm thinking this would be a pretty sweet sweet way to convert the third from carb to EFI.

If you use tunerpro or some, and go to moates.net g to see if an adapter is available for the ecm you are trying to use, and the impedance matches for the injectors and ecm, I don't see why not. if you use that TB, you would probobly need to add a MAP sensor too, but if you plan on just using it for fuel, like the HOWE kits, than it can be done. Again, you need to match the impedance to the injectors to the ECM.
