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.

    • Yeah based on old XRC5964S specs, it looks to be roughly GTX3576R sized? But this 5964S compressor will flow 90lb airflow somewhat similar to the compressors in both the GTX3584RS or G35-1050.. I fully expected the 0.64 rear A/R to choke up top - seems way too small from typical convention - but these are seemingly beneficial over the prior 0.82 results.. Be interesting to see if he comments on the EFR question in that thread - he mentioned in a prior video that BW EFR's were the "cats pajamas 10 years ago", but by the sounds of things all his kits have been using Xona for quite a while now.
    • Yeah it’s still got the oem manual gearbox and clutch, only kinda mods are a blow off valve, coil overs, and a aftermarket intercooler. Also had it for about 2 months now with a lovely midnight purple paint on it.
    • Yeeeppp, been following a lot of the testing on the latest Xona stuff and there are some mental results.  He also went over 1000hp @ 4 hubs on his Mainline with a XRE6364S (63mm) which was also well into the 20psi range before 4000rpm on a 2.5. Crazy stuff. Fwiw the XRE5964S is basically the modern equivalent of their old HTA3582 - would drive nicely enough on an RB25 or 26, but proven capable of a huge amount of power if you want to spicy with rpm tho even at sane boost levels will make stout numbers 
    • The axels in my R33 seem tired, and have a bit of play in them. I cannot find any new of course, not interested in buying used, but I am looking to see if anyone can identify some cross compatible axles. In the states I have seen suggested for S chassis the J30 axles, however for the skyline (as best I can tell) the lengths are about an inch off (2.5cm) on both sides. R33 my measure L 22" R 24.5" GPT L 22.5" 24.25" J30 L 23.5" 25.5"  so shaft length is probably an inch wider. Not sure if someone has another still remanufactured option besides the J30. I figured worst case I can buy a pair tear them down and swap the center shaft. My other option was reaching out to GSP to see if they cannot piece together a set, since the axle stubs are still manufactured, I wouldn't think it be that hard to find a shaft or make a shaft work.
