Flywheel compatibility

Post by Nevada1906 »

I wonder if someone can point me in the right direction.

Right now, I'm building what I call an 860R - a 1995 854 with a B5254T4 R out of a 2004 S60R, driving an M56 transaxle from a 2000 V70. The build thread's over on the 850 and 70 Series forum if you're interested. I'm using the factory ECU and wiring harness from the same donor car the engine came out of, but the transaxle, flywheel and clutch are all miscellaneous 850/70 Series equipment sourced from eBay.

My question is, will the S60R ECU be able to read the P80 flywheel, or do I have to figure out something? I already have to get the ECU reflashed to delete the immobilizer, so do I need to have that programmed in, or do I have to rig some sort of piggyback converter?

Any help would be greatly appreciated.

Thank you.
