Hey all :action-smiley-069:

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. :thanks: 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.

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.

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

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.

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.

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 :D.

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

+1 Power fc

That's not exactly hard though...

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).

      Question about BoV on RB25DET NEO

      By Kapr · Posted

      Wow guys thank you very much for the HUGE info :-) @GTSBoy I have like 30 minutes if test drive with that car/engine and it not stalled once. IMO it ran very smooth so i guess it was not that bad(but asi i said it is stock) That atmo BoV is worse than no BoV or in my case or it is/will be the same? Cuz frankly i rather have little whooosh sound than that sututu 😄 But either way the less harmfull for engine/turbo the better(if the stock is not an option right away) Yeah about that rebuild i talk with guy who will be doing swap and custom pipes...i think i can get stock BoV or get aftermarket which will function the same. Yeah i looked at that R35 option and i try ask my mechanic more about that if he knows. The engine has stock ECU but i can get Nistune for it. On that stock it runs quite well...but i have limited time with it so rly dont know. Ecumaster is this https://www.ecumaster.com/  It is not some dodgy backyard ECU :-)  @MBS206 Yeah but it will be better to have Nistune than the completely stock ECU no? About that "same" atmo/no BoV. The drivebility would be the same? I dont know but i kinda guess that amto BoV would cause more problems than no BoV in my case? Or is the same? You just "change" one sound for the other? Yeah i read many many many topic about hurting the turbo. But no one know anybody that would 100% tell that his turbo/engine blows/get damaged by not running BoV. Of course turbo would be little happier IMO if it has BoV ..but if you do not trash i think i should be good. And as you can see iam already trying to get this right...just working what i have right now :-) Yeah iam kinda the same...i dont want nothing loud and frankly iam not liking that sututu noise that much 😄 i rather have little bit of "whooosh" or no sound at all. Of course in my case it si a completely another world when you came tu Turbo car with open air box and no BoV and you driving the N/A ...all i hear is engine. Here? I heard turbo/sucking and that sututu 😄 @Yeetus So in my case it is really no difference to run no BoV or some atmo BoV like GReddy FV2? The car would drive the same and has "the same" little problems? As i wrote above i kinda thinked that atmo BoV with stock MAF would cause more problems...but then again i dont know much about no BoV either :-)  So to avoid stalling i "cant" just put neutral on stop lights like from higher rpm? Or? Yeah iam already looking for ECU :-)  Yes iam at the same side with thar R35 MAF :-)  @Dose Pipe Sutututu Thank you i (my mechanic/tuner) will look into that) Guess iam taking the Nistune at least :-)

      Here's the workaround with Nistune I was talking about, just add in more timing on the decel table And play around with the fuel cut & recovery, it's enough to stop it from stalling on a decel

      Alcon TA6 Calipers on R33 GTST - Flexing

      By Sydneykid · Posted

      Probably too late to reply to this, but worth a try. It's not calliper flex, the calliper as a whole is moving so it has to be calliper mounting bracket flex.  Calliper mounting brackets are designed to stop the calliper rotating, they don't need to be designed heavy duty to stop the calliper moving in and out.  Whatever it is is not the major cause of poor pedal feel, the outer pistons are moving towards the disc rotor the same amount as the inner pistons are moving away from the disc rotor.  Hence no change in fluid usage, what extra fluid is needed to move the outer pistons is recovered from the inner pistons. For a calliper to move as a whole by far the most common reason is the rotor is not perfectly centred in the calliper.  The first thing I check is that hub face is perfectly clean, bare metal, where the rotor hats contacts it.  Then I check the that rotor is firmly held in place by at least 3 wheel nuts (or equivalent). If all of the above are confirmed to be in perfect alignment then I would check the piston sizes and ensure that the 3 inner pistons and 3 outer pistons have matching diameters (eg; 28/32/36mm).  I have seen a no name 4 spot calliper that had 1 of the 4 pistons a different diameter. Maybe I missed it, are both the callipers exhibiting the same problem? I would remove the transfer pipe and inspect it to make sure that there are no restrictions. Maybe you already have but if not I would return them with the video and have them confirm all of the above.   Hope that helps Cheers Gary

      If you have the original log book and it didn't have a chassis number quoted, then no money required.  I have "rechassied" a number of race cars, no problem as long as you have the original log book.   Cheers Gary
