[QUOTE="EFN, post: 459707, member: 1416"] This has been discussed before. With 4A-GE 20V ECU, it is very-very difficult to trick the ECU simply because 20V ECUs are very dependent and sensitive to sensors and very clever at readjusting it to whatever Air-Fuel map that it think suitable. So technically you can wire in a Piggyback like S-AFC but using Piggyback to fool the ECU is almost futile becoz I never heard anybody done this successfully yet. The only solution is to change the whole ECU...DUH! [/QUOTE]
