R33 Vspec Vs Gtr Ecu

[twotwisted]

Hi

I have done some searching, but have not found a clear answer.

Will a R33 GTR VSpec Stock ECU work with a R33 GTR? and what issues will there be?

I have discovered that changing the ECU in a VSpec can lead to A-LSD problem, so the VSpec ECU sends a signal to the A-LSD computer. However if a VSpec ECU is in a GTR will it operate with no errors or will it produce errors say if checked via the consult port??

Just trying to cover as much as possible about differences for future references, please also post anything else that may be different.

ECU's are the same.

Diff is controlled separately, signals sent to it should not be affected by the ECU used. It should not be affected, if it is - you have other issues.

Hence a PowerFC for a BNCR33 & BNCR32 have the same part number irrespective of what variant model they are.

I used one with A-LSD, no issue. I then swapped to a non-vspec rear end - again no issues.
