Hi guys im wondering if there is much difference in the tunabilty of the nistune as apposed to the power fc?

Im running a nistune at the moment with stock turbo and all the bolt ons and im currently making 272hp@thewheels or 203kw@thewheels with 12psi boost

Im getting ready for a turbo upgrade a hks 2835 kai and just wondering if there is any advantages going to a power fc over my nistune?

PowerFC - IMO best to get the D-Jetro, otherwise NIStune hands down. D-Jetro uses a MAP sensor but takes longer to tune. Great to push a little more from your application in terms of tuning but not a big deal .PowerFC can be tuned every 400 RPM

NIStune - Best bang for buck, streetable, knock sensor, limp-home mode and cheaper to tune whenever you make any mod changes. NIstune is tuned at every 500 RPM.

Haltech ECUs can be tuned every 250 RPM but then you need to find a reputable Haltech tuner.

For response, get the Precision 4828, based on the GT2860RS but billeted and cheaper. :thumbsup:

Otherwise you have the 5128 and 5130 to choose from (the miss-matched GT2871R or the efficient GT3071R replacement).They go on of course but so does the lag and cost.

Lots of mis-information there ^^^^

Power FC has never done me wrong. I don't tune the car, I drive it so I don't care what is and what isn't more tuneable. There is a tuner out there who can work with anything so just take it to a reputable nistune/power fc tuner.

If you've got a nistune stick with it, if you got PFC stick with it. If you got stock, its up to your wallet. I'd always go PFC is I was a stock R33/R34. I'm not doing anything extreme with my car, all bolt on mods so a PFC is more than enough. Don't need djetro, never had issues with a Z32.

nistune will pass an inspection, power FC wont.

I'd be choosing it purely on that basis.

You can put the Power FC gear into your standard ECU housing. NIStune is not legal as it is a modified, programmable ECU. Its just because it looks stock. If you do an emissions test, both ECU's will probably fail on regular fuel and mods.

If you can fit it into the stock housing then thats a good option! Looking stock was the point I was trying to make.

Ok so im not gunna make any substantial power gains with a power fc then?

Best off just keeping the nistune and getting it re-tuned when i get my injector and turbo upgrade then?

Can i get some opinions of good RB25 tuners in sydney who can work wonders with my nistune?:thanks:

regardless of ecu, the car will make xyz RWKW or KW or HP blah blah

there is no legitament reason another ECU will make more power

if it does, the other was not tuned properly

air fuel spark make power not the ecu

pick one that your tuner is competent with

    • Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
    • You can use your VIN to look up the factory part number somewhere like amayama, and then look to order new if necessary. https://www.amayama.com/en/genuine-catalogs/nissan Depending on price you might want to rebuild instead. @GTSBoy I had an interesting insight into US market parts when the Titan rear calipers were sticking. New calipers were dirt cheap, about 20% more than a rebuild kit....they are just considered throw away maintenance items
    • Funny, but really not funny. Thank god (most) f the world has moved on since then
    • Lots of votes for driving onto a plank first; that is the quickest way I've found, 25mm is enough for my case but that will vary by car It also depends where you are going for. On the 32 I can get to the rear diff with my floor jack if I do that end first, and get it up on stands. Then I lift the front from either front tow hook as high as needed, also onto stands. Sometimes I need a small lift on the other tow hook to get it level enough If I do the front first I can't get to the rear diff because of the angle of the car Other options are getting to the front mount of the rear subframe from in front of the wheel (if only lifting one side, or just do both which is a bit of a pain compared to one lift from the diff), or also the gearbox cross member mount on the driver's side if you are  just trying to lift the driver's side. I This is the jack I use; it says 75mm clearance but of course that is only on the lower section so if you have to reach too far in like the diff you still get stuck. https://www.snapon-bluepoint.com.sg/category/Floor-Jacks/product/Floor-Jack,-2-Ton-Low-Profile
    • On the bright side, the weather will turn much nicer for working outside shortly....sounds like you might need to start on a neighbour's garden next
