is there a difference in ECU'S between the models and the years? ie. would an 89 calais ecu fit into a 91 calais or an 88 executive into a 90 calais? is there any differnce or is it all just plug and play?
yep all manufactured by Delco, VR onwards had more crap in them, but when it got to the VS they controlled the transmission aswell i think still on about your cluster troubles??? cant hurt to borrow a mates and test that! but i still think its your loom
yeh, it's stil lthe cluster thought i'd change all clsuter and ecu before tackling the loom but i rekcon you could be right and it will be the loom, so i'll try the 'bridging the connections with mulitmeter' idea
i would say their different, just bcause evertyhing is different about them in regards to clsuter but don't qoute me
The ECMs are functionally the same (1227808) in VN-VP, JD unleaded & JE Camiras, LD Astras/N13 Pulsar manual or auto. but the (plug in) MemCals are different. The MemCal is the blue thing visible with the ECM case open.
