Engine + Driveline / Re: Rev Limit 4000

I got a better look at the tac last night, the rev limit occurs at 4500 not 4000, does this point to a problem with the differential speed sensor and instrument cluster?

If a previous owner swapped the instrument cluster with one from a 325, would it cause the RPMs to be off?

EDIT: Revs go up to 6500 on the instrument cluster printout, so I don't think this was related.

93 318is m42 engine that rev limits at about 4100, showing code knock sensor #1 (1225). 

Would this be causing the car to go into a limp mode, limiting it to ~4000 rpms?
Or is the knock code more likely a symptom than the cause?
