Hi guys, I've been helping E39 and E38 guys with getting 4.6 and M5 gauge clusters to work with their cars. I've studied the 4.6 software and determined which maps and values allow the proper signals to be sent to the oil temp gauge and lights. So far it seems to be working well, but it seems like the oil temp doesn't go much beyond 75ºC / 165ºF, at least when idling. Do the 4.6s go higher than that?
