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?

Nistune can be set up to idle really well with most changes, but as with all such things, spastically large injectors or massive AFM capacity mean that you're working at the very bottom end of the sca

Well, sort of. It is actually pretty easy to determine the relationship, for A GIVEN ENGINE, between MAP and air flow (with IAT correction). And it's not going to be much less accurate to calculate

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

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
