I wonder what else the VCM could possibly be doing for your truck. does it act like a BCM too?

Basically it has everything in it for the brakes, old engine, and enything else that needed computer control. It's a real pain in the but.

just trying to think what the "everything else" is. my 93 has the black box on the side of the master cylinder for the RWABS. not that any of that has to do with the issue you are having. we really need to get a datalog.

you can find info for that computer as well as wiring diagrams here http://www.gearhead-efi.com/Fuel-Inj...Information-42
unfortunately AKAN is not in the bin repository as it was likely superseded with another BCC. someone on here may be able to look up what that BCC was replaced with.

I'm going to have a look for another chip from abother trUck. I have a cess to an 89 automatic with a 350 that I can grab from if needed.

no need for a different chip. once tuning begins the old one will get tossed... do you plan on getting tuning hardware or getting someone to burn and mail you a chip?

I'd like to have the stuff to do it myself. But it's going to be a while before that can happen. Our trip got canceled this year since we had to buy a new car for the girl. Sucked all the funds up quick.
