I am researching and developing a stand alone TBI conversion for AMC engines. I have an AMC 360 sitting on the floor in the garage. It's hooked up to a GM TBI system. I'm using a 7747 ECM with a 2732A chip (24 prong). I have eliminated the electronic spark control to keep this kit economical (I didn't want the kit to require a new ignition mod, dist, and coil). In doing so, I used the negative side of the coil to fire the injectors. ( FYI..It required making a tach filter to reduce the high frequency spikes resulting in a fried ecm.)

Anyhow, I am just one step away from having a working prototype. I just need to reprogram the chip to not read code 42 "electronic spark timing open circuit"

I understand that there are a lot if options out there. I want to stay away from the G2 Chip adaptor because I want anyone to be able to install this without having to solder the circuit board.

What is the cheapest way to accomplish this?

DIYFI.com is where youll find the info if its anywhere. Ive been reading over there alot lately.


Craig Moates site may be a good place to look as well. Google his name, youll find it and they have a forum there where people would be more fluent as to what your looking for.
