240 Need help with ECU numbers
Hey guys, long time reader but first time posting.
Recently I've been collecting parts for a +T on my 1990 240GL wagon
Bit of background is that the car was originally an auto but I swapped it over to an M46, it's got an LH2.4 system on it and the crank angle sensor on the flywheel. The ECU is the 951 and the car is a 1990 but I think the build date is actually late 89.
I'm looking for an ECU that will work for my turbo setup on which I only plan to run stock or around 7-8PSI on the B230F. Most forum posts seem to always refer back to http://www.nuceng.ca/bill/volvo/database/ecu.htm but there I found something interesting that apparently the 951 ECU in my car is only 1993 and onwards and doesn't have a cold start injector. When I've seen my ECU for sale it's almost always out of 940 not 240
My car is 1990 not 1990+ and also does have a cold start injector (worth noting my car often has an idle problem when cold but I thought this was the ICV). So is it possible my car has already had a replacement ECU or is that list incorrect for our market or just incorrect in general?
So my questions are:
1) Is this likely to be my original ECU or is this out of the norm (possibly replaced)
2) If the 951 is my original ECU would I best to try find a 954 (turbo) as I assume it would only be a software difference for boostiness or will I be fine with the much more abundant 563 or any other turbo LH2.4 computer?
3) If I am completely incorrect with all of this can someone help me find the right ECUs for this application?
4) Does anyone know anywhere in AUS that I can find the ECU I need?
Cheers lads, sorry for any noobness
