Hi guys, i've installed a Nistune ecu but i can't take off the speed limiter because the ecu doesn't have the speed signal.
I check the wiring on the ecu and everything seems ok so there is some problem with the cable or the sensor.
Where is the speed sensor on R32 gtr? on the gearbox?
Any replacement kit? i've search on web but i don't find anything for my problem.


Help me guys!!!!!!

This is the back of a GTSt instrument cluster, GTR is very similar.
All wire traces are named, it's easy to track them to their plug.
You can see the mechanical cable connection at the speedo head and the screws are the speed signal terminals.

We don't know if this problem existed before the Nistune so I'd check continuity of the speed signal wire from the instrument to the ecu.
It was common for owners to cut the speed signal wire in previous times.
Attached is the GTSt plug which should have the same speed signal position.
