Sorry for the blond questions I understand that a nistune is a mod done to the ecu but Im still getting the jist of this stuff as I am an old school carby and distributer nollage so I'm getting the drift of this ecu and afm and stuff Cheers

All good, best way to learn is to ask. So does it all make sense now? rb20det, r32 rb26det and r34 rb25det ecu's are the only skyline ECUs that can be nistuned.

Im thinking about going auto in my 33, just wondering if a modified Z32 ecu running nistune will run the auto the same as an r33 ecu would in regards to timing changes on shifts?

we have done it but its not controlling the auto correctly, the separate auto ecus are wired different

Great thread.

I'm trying to gather information to help me decide on the best route to take with my car. A reputable shop in Brisbane is suggesting I go the powerfc over a nistune for my basic mods (pod, fmic, exhaust). Reliability and bang for buck are what I am most concerned with, just want something that is RELIABLE and will leverage the mods I have (would be happy with anything up to 200rwkw).

I was a little confused by what this shop suggested as from what I have read, Nistune sounds like the best option for me??

Both will do what you are asking with no issue, sounds like the shop prefers to tune the power FC and that is why they are recommending it. I would go nistune personally purely because it is cheaper and it looks stock/will pass a defect inspection.

I would put money on they tune power fc's more than nistune and they know their way around it better.

At the end of the day it's your decision and you do what you like with your money. IMO they are both as good as each other and nistune would probally be the cheaper option. I went with the power fc because i found a cheap one and jumped on it, some people love them and some people hate them It's your choice do as you wish.

Ok, so would I be correct in saying they are both capable of achieving the power/results I want and both will provide the same level of reliability? Seems like the only thing splitting them is cost? I would also assume the PowerFC would be more capable when moving onto stage 2/3 tuning and into bigger power figures (which I am not planning on)

Maybe I just need tochat to some other local shops that aren't averse to nistuning. Would the average tuning shop handle both, or do they usually specialise in a particular make?

Both will be fine. Some tuning shops may never have seen a Nistune and may be hesitant. If you can't find a good tuner for the Nistune look for a cheap PFC but Nistune should work out cheaper.

What is 'stage 2/3 tuning'? Play less Need For Speed man :P

The ECU doesn't make the power, fuel+air+spark makes power. And that is all in the tune. A PowerFC is going to be no more capable or reliable than a NIStune unless the tuner is more capable with the PowerFC, etc. There's cars around making over 600kw with NIStuned ECU's.

Lol @ stage 2 tuning

Seriously though a good tuner should be able to tune anything you give him, if they are iffy about nistune OR powerFC I would find another tuner for that reason. They are both incredibly common in the skyline scene so any tuner who does these sorts of cars regularly should have bucket loads of experience with both ECUs.

If you don't think a group of recommended mods done in a particular sequence can be classified as different stages, fair enough. I only know what I have read, so my bad if i'm using terminology that isn't cool.

I think i'll shop around for a good tuner

People just tend to laugh when you say stage 2 or stage 3, because what the hell is stage 3, is it adding a bigger turbo, is it changing your fuel latency value? is it a combination of exhaust housing and injector swap?

It is completely arbitrary so it just sounds a bit silly.

I would get a Nistune and only go for proper standalone ecu (haltechs, motec) if you need to upgrade

Correct me if im wrong but i understand the PFC doesn't retard timing if it detects a knock, just flashes engine check light on your dash

I know you should backout if you see the check light but I would like a little insurance from the ecu if it does happen...

That's my 2 cents

True on the Power FC. Also true on Nistune if you have made the knock maps the same as the main maps, which is necessary one a lot of cars when they suffer from phantom knock (ie the ECU thinks there's knock when there isn't and switches to the soft maps). I had to do this on my R32 RB20DET for that reason. It has run for years like that and I've never heard a tinkle from the engine bay.

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny
