OK... so some background, i have a 85 CGT with an MC1 in it that is currently not running. It turns out i messed up the Mac11c wiring during the swap, but now it is in professional hands. I would like to go with the 034efi fuel only controller for cost reasons (i am a 17 year old high school student so i am kinda broke) but had a question, what are my options for ignition, can i run the stock 4k/cgt ignition, is there some way this system can be modified for retard under boost, or am i stuck with sorting out the Mac11 ecu wiring in order to have a knock sensor and some timing retard. I would really like to go with the efi.... but with my buget i wouldn't be able to pay someone to both sort out the mac 11c wiring and buy all of the efi components, I am hoping there is an alternative, and if there is i trust there is someone here who whould know about it. Thanks for the help.
