you all went the really hard way.... seriously

on my 4afe to 4age swap we pulled the stock 4afe ecu out, modified it to work at a higher RPM, threw it back in....

then as for the engine side.... you need to rewire the alternator to the intake side (i kept starter on intake side), and rewire the ignitor to work out of the old 4afe distributor (you need to have 4afe and 4age distributors that have matching internal gears).... my ignitor is in the cab near the ECU

that was all the rewiring i did. This can only be done with a smallport 4ag using the smallport high ohm injectors..... although the map isn't quite perfect.... it is still running MAP based rather than AFM. Mine dyno'd (with a poor motor) 109.6whp
