i have a sinking feeling it may be. although I don't think the PFC boots up on ACC only when the key is turned to ON.

I recently farked mine and the HC lights up but the screen doesn't come on and engine won't fire... d'oh!

yeah the FC boots up and the hand controller boots when ignition is turned to ON

usually if the FC is blown it will boot the hand controller (if it has power) and display blank or scrambled rubbish

open it up and smell for burnt stuff or check for burnt tracks

I got a question for you. On my Rb25 I have a Power fc with hand controller, when I first had it installed the hand controller would come up fine showing all the channels and information. now when I turn my car on it just shows the APexi PowerFC logo and just sits there. Likes it frozen .. no scrambling info - just the logo appears and just stays there. Any help ?

Not neccesarily

word. seen it happy many a time. fuses fine, PFC toast.

Power FCs are much more sensitive than standard ecu often with a weak ground or weak power supply stock ecu works fine, power fc doesn't. and same goes if you get a short circuit. often standard ecu fine, power FC not so fine. i have nfi why, but that's the way it is.

Hey Mate,

Recently bought a Power FC from a bloke who had his engine out as well - everything else was in the car. We tried to fire it up so I could see if it was working prior to purchase and it didn't work. Put it in my car and it worked fine...we concluded that the other end of the wiring loom needs to be connected to the engine for the Power FC to work...

I don't know if this is technically right, but it happended with me - hope it's the same with your situation as well.

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      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.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
