I need to borrow or if I absolutely have to, buy an AMU ECU for my car.
I am having issues with fault code 17521
Looks like I need to tey a different ECU.
PM me if you’re in SoCal
ive got one for sale , PM ME
I don't think you have ECU issues, rather your wiring of the O2 sensor is damaged. Have you traced the O2 connector back to the ECU connector?
Get the ECU pinout diagram and trace the wires first.
