Sup guys
I Installed a apexi avcr boost controller in my r34gtt the other day. And the only way I can get it to work with the revs and speed is like this.

Cylinder 1. Speed 2.

im pretty sure it should be on on cylinder 6.

also when i rev it out to like 7000rpm the avcr will read 8500, 9000 but at idle the controller reads pretty much spot on.

Bad wiring ? Or faulty controller ?

any one else had this kind of issue ?

Cylinder is set to 6 for RBs and 4 for SRs

Speed is set at 2 for Nissan speed sensors

Throttle is set to point up, i.e. when pressed will trigger 5V or so

I would also check if there's a proper +12V feed going into it. I've seen dodgy installations where it's fed off the ECU harness for power.

Under the steering column, so it's a constant +12V / +13.8 when running... as Joey said, just have a clean earth point using a spade terminal to the body of the car.

Where you located? I can have a look for you, if I can fix it a case of beer will do the trick :) haha

    • Pads for R32 GTS-t, R32 GT-R non V-Spec (Sumitomo), R33 GTS-t and R34 GT-t are all interchangeable. R34 GT uses a 2x piston caliper, hence it didn't fit.
    • Checked with amayama and nope, the full S2 manual set is not available anymore. Unsurprising, but still disappointing as the ? on availability gave a glimmer of hope.
    • I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.
    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
