Depends on what you really want to spend. NIStune's are around $250 or so, whilst Power FC's around the $800-$1000

NIStune, is just a motherboard, which allows your stock ecu to become completely programmable.

Power FC's are a whole new computer, with hand controller, so you can do 'on-the-spot' programming.

NIStune's are not legal, and neither are Power FC's, advantage of NIStune would be that it is virtually impossible to detect from a coppers point of view, apart from the USB port that is made to allow the USB cable to plug into the laptop to tune,whilst a Power FC is recognisable from its Apex'i casing. Hand Controller is detatchable..but still, if a cop wants to have a look inside your kick panel, you are a sitting duck.

My point of view anyway.

My Power FC cleared regency earlier this week... he took a good look inside the kick panel. :D

+1 however I will clarify that some Nistune boards use the stock consult interface - so effectively there is no way to tell unless one disassembles the ecu housing (and then removes the outer circuit board) ... nistune supports the std nissan consult interface too so there is also that...

tis illegal yes but virtually impossible to spot unless they know specifics.

also, powerfc circuitry fits inside stock nissan ecu housing, mounting it in a stock housing is a common stealth mod

ok thanks I got a r32

The differences are that P-FC has 20x20 maps and Nistune has the factory 16x16 maps. This really doesn't make a difference as the ECU will interpolate between the map points. So really unless you are making huge power like 600+hp and you need to stretch you map to cover a large load range you will not be at a disadvantage, and really an extra 4x4 points isn't increasing it dramatically anyway.

The Big Difference.

Nistune retains Knock Control where as P-FC does nothing to control knock except flash a LED light on your dash. So Nistune will richen you fuel map and pull timing out ignition map if a knock incident is detected but P-FC will flash at you while the engine is pinging it's tits off.

The cost.

Nistune: Board ~$250, Software/Licence ~$200, Cable ~$100.

Really all most people will need is the board, if you want to play (at your own peril) or data log then you can get the licence and the cable. Not sure whether the OBD2 tunable boards need the cable.

P-FC: ~$1000 second-hand, FC-Logit ~$450.

Without FC-Logit you can't do the things you can with nistune and the software.

Knock control from Nistune is great however you will find that the controlable map points are very limited(up to 4500rpm only) So after this RPM both nistune and PFC will let the engine Ping...just the PFC will let you know about it

The Resolution of the Nissan map is less than the 20x20 of the PFC which gives smoother more accurate response at any power. Especially in the transition onto boost area where high resolution can do wonders to drivability.

They are both good for there respective cost.. but you do get more functionality when you pay more.

What do you mean by this?

the controllable map points are very limited(up to 4500rpm only)

There are two completely different Maps. One regular map and knock map both maps are 16x16. When a the knock count gets about a certain point it switches from one regular to the knock map which has all the 16x16 resolution that the primary map has and isn't limited to 4500rpm.

Are you saying that after 4500rpm it won't switch to the knock map?

yes, the controllable area's of the Map are limited. I'm sure the Nistune guys can fill you in. Since your also in Adelaide...we most likely talk to the same person =) Especially if he drives a mazda 121 with a twin cam.....

Never heard of the nistune not having knock control after 4,500rpm. Probably better off spending the extra money and getting a PFC.

Don't get scared off a Nistune based on a "he said they said" basis. Call Nistune themselves and speak to the guys direct. Nistunes retain knock sensing throughout the rev range ... PFC will just flash a light at you.

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again? 
    • I haven’t yet cut the chassis, maybe I switch to a reverse flow. I’ve got the Intercooler mounted as I already had it but not cut yet. Might have to speak to an engineer 
    • Yes that’s another issue, I always have a front mount, plus will be turbo plus intake will big hasstle. I’ve been told if it looks stock they’re fine with it by a couple others who have done it ahahaha.    I know @Kinkstaah said the stock gtt airbox is limiting but I might just have to do that to avoid a defect so it atleast looks legit. Or an enclosed pod so it’s hidden away and feed air from the snorkel and below Intercooler holes like kinstaah mentioned. Hmm what to do
