The Pros And Cons Of Running A Apexi Pfc With Rb25Det

[Nissan Nutter]

Hey all

I'am seriously considering putting a rb25det in my 32gtst and just wanted to know of the pros and cons of running this engine with a apexi pfc?? Have been told its better to run a nistune??

any feedback would be much apreciated as i don't really want to change computers. in advance

Seriously its upto personal choice. People can say Nistune, Power fc all they like at the end of they day you get and do what you want to your own car! Different tuners will say different things i like power fc because of.. I hate Nistune because of this.. At the end of the day on a modified car any aftermarket ecu is better than stockie. Just look past some of the bullshit people will say and make your own choice based on your own opinion.

Nistune is cheaper in overall terms.

However a PFC will also work fine.

The cost difference is not massive so go talk to your tuner - and pick whichever of the two they are more comfortable with - problem solved that way.

I didn't make my own choice based on my own opinion at all. I spoke to the person I wanted to tune my car and went with what he told me to get. End of the day the tune is what counts, you're not going to make any more power just running a Power FC over a NIStune. Pick a tuner, then pick an ECU to suit them.

PowerFC...I only say this because it will hold it's value better than the Nistune, come the time you sell it, given they aren't making the PowerFCs anymore. That's right, my decision comes down to what it's worth on the second hand market...because the rest of the differences between Nistune and PowerFC them are arbitrary / personal, e.g. hand controllers are cool.

Also if you decide to change tuner for whatever reason then the power fc is far more versatile...plus with the handcontroller you can keep an eye on the essentials

Power fc is good because of the hand controller. U can monitor the engine vitals which is a great thing. But this also attracts the police.

Nistune is more cost effective but is very stealth and will get the same results as a power fc tune

you can hide the hand controller rather quickly or have it stashed in the glovebox etc

Thanks for the advice guys much apreciated

I also have a topsecret computer that came with the car from japan(its just sitting in the shed now) and was wondering if anyone had the software in aus to tune it??

I only changed to a power fc because i was told buy some tuners that no one in aus could tune the topsecret computer.

Well NIStune software is very user friendly, I know most tuners in Perth don't mind tuning it. I think they are both widely supported.

The hand controller is very useful for the Power FC, you can do the same thing with NIStune using a laptop but it's not very convenient lol. Only thing I don't like about Power FC is it has no knock control. I imagine not too big a deal if you have a hand controller, but if you don't then your engine could be pinging it's head off and you wouldn't even realise until it was too late.

Only problem I have with my PFC is "power fc desease" or......Airflow Reversion.....DUN....DUN....DUNNNNNN

If you have a large high mount turbo, be ready for it

[wolverine]

^^ I didn't know that ECU's blew or sucked air.

Hang on a second.. what RB25? R33 RB25's can't be NIStuned easily, you need either a Z32 ECU or an RB20 ECU + window switch for VCT.

R34 RB25 can be NIStuned very easily.

As said, pick a tuner and go with what he is comfortable with. In our state, there is no shortgage of good NIStune tuners.

Also, if you think monitoring engine vitals is handy then do what I do with NIStuned and stock ECU's.. I run a carpc with Datascan and a consult cable permanently hooked up, infinitely superior to a little LCD screen.

That's not exactly hard though...

LOl? And who told you it doesnt have a Knock sensor? IF you have one it must be broken or you havent picked that option .

Cause my Power FC has everything from Inj Duty to Knock to Air to Water temp. No gauges needed here mwahaha

+1 Power fc

Knock control not knock sensor.......

[bubba]

Didn't mean it was hard, just meant it's not as plug'n'play as a PowerFC or as simple as just soldering a board into an ECU as there are also some wiring changes needed for RB20 ECU on RB25.

LOL, yeah the little 40mm x 30mm (or whatever) LCD screen is a great replacement for gauges...

nistune + z32 ecu + wiring loom changes < 1000

R33 power fc < $1900 not made anymore

Plus tuning

nistune does have knock control (some models)

Power FC has knock readout on hand controller

Pretty sure most Skyline models have active knock control but only VLT, S13 CA18 and HCR32 RB20 can display knock levels (if you have a laptop/carpc hooked up).

R32 GTR doesn't Yet anyway, Matt from nistune is working on it afaik
