A R34 Gt-r With R33 Gt-r Ecu, Pinouts, Help?

[Jonathan Bauer]

I'm working with a skyline that's a R34 GT-R V-Spec.

For some odd reason, someone has moded an ECU from a R33 GT-R into it, and changed the ECU pinout to get it working. Now the car starts, and basically runs as normal, but 4WD is not working, and Nissan Consult can't find most of the things it should find.

We have tried 3 different ECUs for R34 GT-R V-Spec (original, Mines, and Apex Power FC) but the car doesn't even start. Then when we tried with 3 different R33 GT-R ECU's it started without any problems.

In a comparison to a standard R34 GT-R there are more wires on the fixed one (2 more), and all the colors are completely different. Allthough, the two R34 GT-R are different year models...

Now I have downloaded ECU pinout diagrams for R32 GT-R, that I have understod is the same for R33 GT-R. Am I Right?

Also tried to find an ECU pinout diagram for the R34 GT-R, but have not found a complete one. For R34 GT-T no problem, but for the GT-R model hard to find with all the pins. Found three with some of the pins, put still missing some.

Anyone got one complete?

Has anyone come up with anykind of similar situation?

Does someone know what are all the differences between the ECU pinouts between R34 GT-R and R33 GT-R?

If anyone can help me, thanks a million.

Cheers,

Jonathan
