How Does Nistune Work?

everyone is telling me to get a nistune done on my 33, i know that its a computer upgrade to your standard ecu, and it unlocks more potential. what potential is that? do i need to change engine components or will it run on a stock standard engine? and most importantly is it a plug and play or do i need to take the car to a dyno to have it tuned like i would for an aftermarket ecu? any info would help. oh and how much does it cost to get done?

It's a piggyback board that is put onto your standard ecu, It's fully tunable and yes you will need to go to a dyno to get it done. Most places will charge around the $600 for an initial tune. Yes it will run on a stock standard engine.

cheers thanks for that.

My question is, why do you feel you need to change to a programmable computer? Are chasing more power?

But yes, NIStune all the way as far as i'm concerned if you dont need all the extra features of an ECU such as a Haltech, Link, Microtech, Megasquirt etc.

WARNING.

You cannot put a Nistune board into your R33 ECU. If you want to Nistune your car, you will need to get either an R32 ECU or a Z32 ECU and do that. There are differences between them. The R32 does not control your inlet cam. You will need to get a window switch of some sort to re-enable VTC on the inlet cam if you use one. The Z32 ECU, on the other hand, does control VTC, so makes that easier, but there are some other hassles with using a Z32 ECU on a 25. Your best bet is to google and read up the very many threads on this and other forums on these topics.

The main reason to put Nistune onto an R33 is to allow you to turn the boost up to 12psi (about the limit for standard turbo) and then tune out all the extra fuel that the standard tune puts in at that sort of inlet flow, and also to wind some timing back into it. The stock tune is horribly conservative. You will make more power and use less fuel.

Oh, the other reason to go Nistune over any other programmable ECU option is that to pretty much any cop it looks just like a factory ECU and they would actually have to open the ECU up and look inside to see that it has been modified. Pretty close to the only defect free ECU option available.

that was exremely usefull thank u. ya i am chasing more power, but from what ive been told my standard ecu is shitting itself. im replacing the engine as the engine has lost compression, and my friend is buying it off me. the problem then lies that if i put a new engine in, the ecu is going to give me shit. its overfueling on standard boost and at 12psi, im regestering all 12psi so there is no boost leak but it feels like im not hitting boost at all, it drives normally, no noises or missfires. but put on a dyno it has 140rwhp. so ive lost about 60-80hp somewhere. i thought it was compression (140psi wet) pritty much even. i know its low but everyone said i still shouldnt lose that much power, as well some one on here told me that the factory computer is set to over fuel itself when dickheads just up the boost without considering the AFR. and aparantly they tend to shit themselves or that specific part of the fuel map. i dont really know im still trying to learn.

Yeh most plug in ECUs can use the stock cover these days. Can do the same with VIPEC, adaptronic etc.

I wouldn't go NIStune with an R33. Personal opinion. As has been said, go read some of the threads about all your choices, there's a gold mine of info here.

What do you guys consider an acceptable quote from a business to supply the nistune chip, mod a z32 ecu to support the nistune and then install and tune for an r33 gtst?

Im guessing i would have to supply the z32 ecu so exclude that from the cost...

      Jacks that fit under GTR lips that can reach the subframe?

      By joshuaho96 · Posted

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.

      Neg, the top one is actually for the front. The sizes are 18x10.5 +18 and 18x11 +32.   I measured many times but I'm sure I'll have problems as this is the thread for problems.

      Just one thing; tapping tapered threads is tricky. Taps are always tapered and you would generally run it as far as you can, but with a tapered thread you have to stop much sooner otherwise the wide part of the taper will run in too far and you will have to thread the sensor in too far too as well (possible that it will never make a good seal) BTW nice wide wheels, I guess the top one is for the back!
