[boosted_32]

Where are you located?

Call Matt on 0403 358 142 his the one selling these, If you send him ur ecu he will fit the chip and post it back for $250 including the nistune chip.

There is an orders page at www.nistune.com

As well as FAQ with your options for R33 RB25 listed in here

Awesome piece of gear, i'll deffinetly be using it. I like the idea of re-mapping the original ECU and still having the fault codes for diagnostic work. Not to mention the price

One question i havent found an answer for is, can you use the factory boost control solinoid to adjust boost? I was thinking seeing that your playing with the factory ECU then it might be possbile to adjust what the boost control solinoid is doing too. I also noticed that there is a spot for the consult display to tell you if its operating or not. In a BNR32 will this be possible? That would put the icing on the cake, but no big deal if it can't. An aftermarket EBC might be able to give a more linear boost curve anyway..

Also another question, would the NIStune system remove the 180km/h speed limiter?

This might not be the best place to ask these questions?!?

We tried to get this to work a while ago with pete (he makes the boards) and we couldn't get it to work, there (at least in a S14) is a whole map you can configure so you can actual plot a whole boost curve, mind you we couldn't get it to work, but we were limited by time and he may have it working now.

[Godzilla32]

Oh ok thanks for your reply. I cant get over how powerful this software is. Not that i'd completely know but it seems nearly more powerful than using a PFC?!? I found an answer to my own question after asking about the speed limiter, looks possible to me. Also setting the rev limiter would be handy.

Anyone else had any luck using the software to adjust boost using the stock solinoid?

hey guys just read all this im thinking about getting a chip now whats the cost on everything i need for a rb20 ecu???

It is very good once you get your head around it all. He is working on making the ideal fuel target table, so you connect the wide band up to the lap top and it will adust the map to suit your ideal mixture table, just like Autronic etc will do.

One thing that we did have slight issue with but haven't really looked into it too far is some type of self learning it has, sometimes you will go back and its alot richer or leaner then it was set to, there is a tab where you can clear all that learnt data (Id have to go back and check exact name was a while ago) then it all returns to normal. We asked pete about it and he wasn't too sure about it.

[Godzilla32]

When you say 'go back' do you mean look at the tune that you have previously burnt to the chip? Or just during tuning? Im guessing the latter..?

We tuned the car, then a few days later ran it up again and the AF curve was the same shape, but from say 12.5:1 average to 13.5:1, we were puzzled with what was going on, stuffed around a bit and cleared the computer and went back to normal, so not sure what it was "self learning" or if it can really do that but something was a bit weired. We asked pete about it and he said he never seen it before and few other people said the same, but i don't know how many people bring it back to redyno it to check. Mind you seems to be fine again now?

[Godzilla32]

Ok fair enough. See how i go when i eventually purchase it.. Thanks for your input

BTW Matt has informed me that its possible to map a boost curve with NIStune using the stock boost control solenoid but only on the BNR32, S14A, and S15. Unfortunetly there is no map tracing for the boost map. You can however ready the map trace off one of the other maps and use that to know what cells to adjust. The only down side so far is they havent finalised knock sensing on NIStune so that is still to come but Matt emailed me today saying that last night they had it working while tuning a HCR32 and it went very well so its just a matter of time really

ok did u guys get an r32 ecu with nistine installed on it?

i looked up NIStune.com and the faq's said

10. Do you stock anything for R33 or R34 Skyline

We do not stock boards for R33 or R34 Skyline, however contact Sam at http://www.drdrift.com.au who can get a Japanese EPROM board. They cost about $1000AUD. These will work with a Moates emulator and NIStune for real-time tuning an R33 with full consult map tracing and logging.

Your other alternative is to use an R32 Skyline ECU or Z32 300ZX ECU. The R32 ECU will not support VCT and several other features. Z32 300ZX ECU can be remapped to run R33 RB25 engines with some minor wiring modifications.

so im confused have they worked around it now?

[BoostdR]

The std boost control solenoid needs to be plumbed into the wastegate line like a normal controller, the factory plumbing will only allow about 2-3psi change no matter what you do. Then changes to the map will make a real change.

I've been thinking about modifying my R32 GTR, should I pay the $1000 for a PowerFC, or $400~ (I think I only need the board if I'm going to have a workshop tuning it for me) for the Nistune?

[NISMO]

For anyone considering the Nistune, just got mine done and love it!

As everyone else i was tossing up between this and a power FC. Spoke to my tuner who said there is absolutely no reason not to use a Nistune and it's more than capable for some very high power levels.

All up for me costs were $750 including 4-5hrs tuning and I''m rapped with the results.

Tuner had no probs whatsoever with it, and my N1 is now putting out 276.5 rwkw on 16psi, with a bosst controller, pods and exhaust.

[Moodles2]

My Nistune is in the mail at the moment, I've asked Boostworx and Morpowa and they both tune the Nistune cheaper than a PFC.

this is usually caused (form some ive seen come in) by too much timing in the map somewhere causing it to switch to the knock maps (richer).

Best bet is to get some decent knock detection (gizzmo K-mon, knock box etc) and tune the car, switch it off and do another run if you find the AF changes copy your fuel map into the knock map by pressing KNOCK COPY button and this will ensure both maps are the same. Turn the car off and the restart it and do another run, and repeat. if the A/F is constant after making the two maps the same then you know the issue is your timing map (causing it to switch). Remmeber to richen the knock map up after your done fixing the issues in your timing map..

So far ive had no issue with shifting A/f values.

The NISTUNE stuff is extremely good value for money and im yet to find any real limitations in 99% of applications.

Do you do these?

If so wanna trade one of these for an r33 gtst power fc?

PFC is still the best option for r33, the remap is too dear and down on features, the rest are AOK.

[BeEnAr]

My ECU is getting Mines chip removed this weekend and NIStune going in during the week sometime. Then off to see Trent at Status Tuning to get teh tune done!

TurboTech is going in too.

Can't wait!

[W0rp3D]

what about using a z32 ecu, have you played with this option yet, if you can get it to work in sure a lot of 33 owners would be interested.
