RR and oil pressure

[Harrismarine]

Is there a reason my RR will not log oil pressure, when I go to the vehicle computer it logs it OK (LS1)

[joecar]

Oil pressure can be logged only if the VIN is from a Corvette (since Camaro/Firebird, GTO, Commodore did not connect oil pressure to the PCM)...

i.e. VIN has to start with something like 1G1YY.

[Harrismarine]

So full flash the program that allows oil pressure and put in calibration should work?

[joecar]

No, just use the scantool to change the VIN (you have to come up with a valid Corvette VIN), see if that works first.

But if oil pressure is low it comes up with a warning on the dash so is it only connected to the BCM in a Holden ?
