1970-1995 Range Rover Classic
Hi allI swapped ECUs from a 13cu on my 87 to a 14cux from a 94 3.9. Truck runs great, but the EFI light came on after a 45 minute drive. I'm wondering if the ECU is looking for a signal from a sensor not present on my 3.5. Where would you start?Again, it runs great. If the EFI light persists I can simply swap my old 13cu for inspection.
