i am asking on behalf of a friend
he has an ASTRA MK3 ESTATE with engine C20XE
he had a problem with the ECU
and he replace it with an ECU from ASTRA MK2 C20XE
is this correct ?
i know that the ASTRA MK3 HAS THE MOTRONIC 2.8
AND THE ASTRA MK2 THE MOTRONIC 2.5
two major problems appear the car cant go above 5.500 rpm the cut off system for rpm
the engine light comes on
and the tech 1/2 shows Lamda sensor which was replaced
with a new one and the same fault appear again
could the ECU be from a non catalysator ASTRA MK2 and does
not identify the lamda sensor ?
and in generally the car does not perform well
do these m2.5 and m2.8 ECU HAVE large differences as the are for the same engine C20XE
OR THIS ENGINE IN ASTRA MK3 AND MK2 ARE DIFFERENT EDITIONS
I HEARD SOMETHING ABOUT THE AIR FLOW METER IS THIS CORRECT ?
AND IF SOMEONE KNOWS ANY OTHER DIFFERENT THINKS TO MENTION
THANKS IN ADVANCE
