I'm sure you could swap with a place like niswreck or just buy one then sell yours, and o2 sensors arn't the end of the world.... I got my nistune suplied and re-mapped for $750.. and i actually took out my power fc to do so...

Power fc's are great but you must remember they are not calibrated for a forged motor... each forged motor that is hand built/ not as tight tollerences/ run in differently are essentially different motors have more or less piston rattle and can produce a different harmonic frequency.

nistune have far better knock protection over powe fc, keep all factory settings, cops cant see it, amd a hell of a lot cheaper.... im a really big fan

WTF are you on about?

You can tune a Power FC much the same as a stock ECU with Nistune. Your motor internals have no effect. Knock detection uses the same knock sensor regardless of PFC or Nistune.

But I too am a fan of Nistune :P

yes they are the same in the sence its a editable ecu... but as far as i am aware power fc does not have a knock map, where once knock has been detect above limits it hits knock map and retards 4degrees of timing???

also yes power fc uses knock sensors, yes nistune uses knock sensors but what good is both protection if you have piston rattle that may / or may not have same frequency as what nissan engineers spent many many hours putting a "STOCK" motor into severve detonation to record the frequency???

it was just a point i mentioned, as many people buy power fc because it has a live "knock count" and spend 5X as nistune but as many tuners have said to me as soon as you change the slightest thing eg, exhaust your changing the motor and possibly the harmonics.

another example people might have devoleped a knock count to find something loose in the engine bay to be the fault not detonation.

      LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.

      M35 Aftermarket Fuel Pump

      By dawhitehonky · Posted

      I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy

      If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.

      Rapid-fire squeaking/creaking from rear suspension

      By GTSBoy · Posted

      Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.

      Jacks that fit under GTR lips that can reach the subframe?

      Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
