You're going to get told to plug it in to a diagnostic laptop. Only way you'll find out.

4.5rpm in 5th = 120mph
Prob best to get a passenger to monitor the ecu diagnostic screen

But... afaik faults are stored in the ecu so you can just connect and see what already logged.
Probably a good idea to take note of the faults, then clear them and go for a spin?
