2.5tdi > 4.0 swap. questions on PCM and obd
I have researched some more after posting my last topic and so far i have verified that the ax-15s bellhousing is indeed a 4.0 boltpattern and i belive getting the engine in the bay wont be anything hard. I know that the powertrain control unit has to be swapped out for it to work at all. but as it is the first car that has any kind of electronic drivetrain controllers in it i'm going to mod, i don't really know how those things work. so my question is what does the PCM actually contol besides obiousely the engine and the (automatic) tranny? also are there any other controllers i should know about when doing this?
Also, I belive the 96 diesel i have should be OBDII (need to verify it). But as i would need to swap out almost if not all the electronics concerning drivetrain control, would it be possible to to get an OBDI donor car?
You might ask why not just build it on a genuine 4.0? I think it will be easier to do it in the diesel as the cluch pedal assembly, tranny mounts and stuff like the driveshafts are already set up in there.
So far my mind is firmly set on doing the swap, but before i start looking for a donor car to get the engine and electronics, i'd like to determine if i am at all up to the task.
Any input would be greatly appreciated, even if negative. Please help a guy learn his Jeep stuff
