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

      Need AC Compressor for R32

      By GTSBoy · Posted

      R12 has not been not available for....decades now. Propane is not a great replacement. (I mean, it's a great replacement, but it is a bit too flammable). R134a being the only way to go forward with an R12 system. The design pressures etc, are close enough to R12's to work. The ability to move heat around is close enough to R12's to work.

      Out of curiosity, what's the reason for converting? I think @R3N3 might have the Frenchy's kit in the R33? I somehow think of you as the ambassador for realistic and clean street-driven setups nowadays

      V35 Overheat + Coolant Boil & Overflow + Engine not Starting

      By V35_Paul · Posted

      careful when running the car after a boil over. Ive heard you can lose enough coolant that it won't show the right temps because of too much air in the system (or something like that). Make sure the levels are good before trying again.  Maybe a mobile mechanic can come have a look with their scan tool ?

      OK, just for some extra clarity - there is more than one option at Frenchy's. 1. You can buy the whole kit - with or without the actual compressor. The whole kit includes mounts, hoses, condensor, etc. That's either ~$2200 or ~$2800. No surgery required with this option. 2. You can buy just the bracket (~$600), or the bracket with the compressor (~$1200). Either of this or the above option "without the compressor" is if you already have an Echo comp or you are able to source one locally. Whatever the case, in this option, you will need surgery done on your hoses to adapt to the new compressor. When I said "the Frenchy's kit", I meant the whole kit in option 1. It is obviously somewhat more $$ than a $1500 OEM compressor. But if I had to spend $1500 on an OEM compressor, I would certainly consider spending double that to renew and significantly update everything forward of the firewall. Another option is to rebuild your original compressor. My R34 comp is currently dead and I will be most likely doing that to it if the spare one in the shed is also leaky.
