you cannot drive a 4AGE 20V with this ECU, the 4AGE requires individual injector control and this ECU works on group fire control for the injectors, it also does not have a cam sensor signal input. It solely works off a crank sensor timing signal, and furthermore the 20V has a vvt pulley which this ECU cannot drive and a heated O2 sensor circuit too which this ecu lacks.
This ecu says its a 5AFE and thats the only engine it should be driving, people have stuck it on a 4EFE and 5EFE to make it work but its not the best solution.
