Right but when that board goes bad the needle is usually just pegged. It's odd that it only gets hot in the 5k rpm range.

They can be erratic when bad.

A M cam doesn't make any torque or much hp at 5k rpm.

Just a thought. Bosch 55 amp alternator current rises with rpms. 35 amps at 2000 rpm, 48 amps at 3,000 rpm, and 53 amps at 4,000 rpm. I assume higher at 5,000 rpm, but my book only shows to 4,000 rpm. Voltages might grow a bit also. The voltage regulator is supposed to keep the voltage steady, but VRs aren't exact and the voltage stabilizer on the instrument cluster circuit board isn't all that precise.

As others have mentioned, it only takes a few minutes to bypass the temp faker board.

Just bypassed the faker board and drove around for a bit. The temp rose to just above half way but stayed there, even after a decent bit of abuse. I think that was my problem but I'll keep an eye on it in the future

Go hold limiter for 5 seconds or do a burnout.

Either way, neither of those things will cause your motor to get warm. Only after about 45 seconds of 5k rpm burnout did my motor start getting hot.

Well yeah, but mine showed it getting hot after any redline action at all

Yeah which definitely won’t cause an overheat if your cooling system is in good order. Go redline her again’

Engage 1st, then drive around for about 45 seconds or so at 25-30 mph while going up a somewhat steep hill. So, high load, high rpm. Check temperature then. Should still be just above midpoint.

If you can or even want to, add a VDO temp guage for peace of mind during your years of ownership
