EL ECU into XF

1 post in this topic

Hey guys!


So I want to chip my XF EFI Manual and I am told a J3 won’t be compatiable with the XF ECU. So I have a EL ECU and complete wiring loom.


As I understand it, I can connect a few inputs only to the EL ECU and then instal a J3 chip and tune it a little more aggressively. My question is, what inputs need to go where?


When I bypass the XF ecu for the above, can I continue using the XF ECU and loom for the balance?
