I bought an extra MS43 ecu but it has a different hardware number on it so I don't know if it will work. I don't want to experiment with my stock ecu
As long as it's an MS43 it should be okay. My own car's DME hardware number actually changed when I flashed the Euro tune onto it (obviously the sticker didn't change, but the references to the HW version in the software did)
