Range Rover Mark II / P38
I have a BECM and M5.21 from the same car here, a 1999 NAS 4.6
Have unlocked the BECM, enabled EKA, disabled alarm, disabled immobiliser.
Same security code in both Bosch M5.21 and BECM.
Still comes up with the same.
put his Engine ECU in another car, starts.
but won't talk to his BECM.
