I would like to rebuild my fuel injection system; from the ECU forward, if possible. I want peace of mind in my rebuild, so swapping out all electrical and fuel components with new (aftermarket recommendations okay) is what I want. The 123Ignition thread intrigued me, but I'd have to switch to the L-Jet to achieve the programming which that thread commented on. I am unclear if this swap is worth it, or how to accomplish it. Anyone know of sources and a punch list for completely redoing this ignition and fuel system? Appreciate feedback.
