Hey I have just changed engine from a 1,8 to 2,0. I think the 1,8 enginewas B18U, but I`m not sure[:-]
Anyway.. My problem is that after I changed, the engine only goes up to 4500 rpm. When the car stands still, the engine sounds very poor.. And the pollution is very high. Is the ECU different on this two engines?

Thanks for answer

 

I assume you have a 440 or 460 with those engine designations.

The control units are different.

 

Okey, thanks for answear. Its a 440.

But are there one controll unit for the injection and one for the ignition? And where can i find them in the car?

Thanks again.

 

The control unit for the ignition is the same for both engines. It is in the engine compartment attached to the bulkhead (firewall) and has the ignition coil, again same for both engines,fastened to it.

The Engine Control Module on the 1.8 is under the right hand fascia. For some reason, knownonly toVolvo, the ECM on the 2.0 is behind the right hand kick panel.
