I just put my pFC into my GTS-T and things are not going well.

I am just running with the base map at the moment and have it booked in for a tune for late jan.

I have a turbo smart bleed valve running 13psi on high and stock on low (about 7psi).

When i have it set to high boost the car runs like some body has put a orange up the exhaust (it almost feels like some sort of really fine ignition cut)?

On stock it run OK, I though it might be the fact that the PFC's base map is not designed for our fuel, or maybe the PFC does not run with bleed valves?

PS, there are no warning lights displayed or anything like that and the car is holding boost so I dont think there are any leaks in the piping for the FMIC or anything like that.

Any idea's

Hi GunMetalR33, I would have someone watch the Commander readout when you are driving it at full boost. If it is retarding the ignition timing or adding some fuel it will show up on the screen. This is not dangerous, in fact the ECU is protecting the engine.

Another issue may be the AFM maxing out its voltage, this is a dangerous situation. You can also easily see this on the Commander. If it is running lean it will result in knock which will show up on the dashboad warning light as well.

I would try running the boost at 10 to 12 psi and see what sort of results you get. It may be at 13 psi you are just "over the limit".

Hope that helps

The base map may be fine for some people but it may not be fine for everyones car with infinite variety of modifications.

I would be watching the commander very closely especially the knock sensor reading.

I found that with the base map on my car it knocked too high at full throttle so i pulled it out until I can get it tuned.

I ran for ages on base map, but with only 0.6bar boost.

When my car went on the dyno to be tuned, I was glad I had kept the boost low, as it was still running very rich on boost and had AF ratios in the 10s.

Once it was tuned at 0.8 bar, with AF ratios at 12, it still had nearly 90% injector duty with stock injectors and fuel pump. Also, my AFM had run out of resolution (5.115V) by this stage too.

      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
