I want to put a 350 ramjet in my '87 iroc. It has the stock 350 tpi 700-R4 running in it now. If I pull my engine and ecm to trade off for the ramjet goodies, what will be left un-controlled? What I mean is what does my stock ecm control that the one responsible for the ramjet engine opperation won't? Torque converter lock-up, tach, speedo, cruise, fuel pump, fans???? Does the stock ecm control these, and if so what can I do to get around this. This must be similar to a tpi-carb swap, right? Have any of you guys done anything like this??

 

Lock up, knock control, canister purge, ac fast idle, and maybe cruise, not to sure.
