I have a E36 318 late 1999 (v) convertable.
I think some history is needed before anyone can help.
the head gaskit had gone and so i desided to install a 2L engine.
have installed the engine, gearbox ECU EWSII diff and prop. starts great runs wonderfully but
the rev counter is reading wrong. ( the rev counter is counting 4 cyl and not 6 cyl)
so when i'm going 70MPH im reving about 6500RPM which is wrong.
the clocks i have are 140MPH dails, black back.
the clocks from the 320 donna are also 140MPH dails but the back is light blue.
when i plug the other clocks in the car wont start.
dose anyone know how to get the correct revs on the clocks is there a jumper or something or do i need to get then programed to the system. thanks
