Where and whats Menty mate, Im also lookin for similar but 18s

My cars manual mate, not sure if it would work on an auto

This Nistune was tuned with the Z32 afm and Siemens 630cc injectors. As for how much the tune in an ecu is worth, you have the right to voice your opinion; I have seen many go for much more than this. A tuned ecu like this saves you a good amount of money in the long run as well, which could be used to get other go-fast gear.

Up for sale is a R34GTT ECU with Nistune type 4 board installed which has a tune file on it from JEM- made 286rwkw at 18-16psi on Precision 5558 turbo ( which is almost identical in size to a Garrett GT3076R). Will go on stagea (RB25DET NEO) as well as they are essentially the same engine/ecu minus traction control. So if you have a similar sized turbo and supporting mods, you can just plug in and drive away safely to your tuner for a touch-up tune which is cheap, generally $100-200. This includes re-sizing/scaling your injectors and afm in the software settings. A full tune only (like what this ECU has) will set you back $800-1000 at the usual recommended tuners. Its in perfect working order and there is nothing wrong with it, I have just gone down a different path, chasing more power/ more features in an ecu. Only $550 including registered post anywhere in Australia. Ron 0416424446, or pick up from Parramatta NSW

Yeh, thats what the theory is - that it moves too fast to get hot - reality is its too hot to touch after a long and decent flogging, and its not my intercooler cos the cooler-out pipe is always at outside air temp to the touch. And yes got exhaust wrap around my piping over engine bay where I could wrap it - makes huge difference to previous without. Very good mod, this. And water spray was my previous consideration but seems this isn't really popular - was intending to go down the route Mafia did with his 33..

109? I reach 150 and sometimes higher after a hard flogging for say 10-15mins, back off straight away when this happens and let it cool down - tune has been massaged to goodness by Unigroup but is still not ideal for circuit work because I think timing could be high. Intercooler is fine - exit pipe is cool but crossover pipe over engine gets too hot to touch, so reckon its the heat. Pump, injectors all good. Only does it in 3rd gear and up at 6000+ rpms.

I have a 34gtt that does this on downshifts and especially under load, it bogs down for 3-4 seconds and loses 60% of power or even more, its that bad. I have recently found it sometimes does this on up shifts as well but only under load when shifting a bit early up an incline etc. My tuner found the map tracer cell in my power fc jumps 5 cells when it does this, pinpointing to a high voltage drop in my z32 which is possibly measuring more air from b.o.v. reversion n causing the ecu to retard timing n add more fuel. He said it is most likely my bov angle pipe causing afm reversion- not an ideal entry angle- see pic

Bump and fixed price now due to people wasting my time. NON negotiable sorry.

Bump! Please don't waste my time with stupid offers, thanks.

Sold!

17X10X6 from memory- came off my R34GTT

This is the quietest 3 inch straight through muffler I have used and still gives that sweet but angry RB sound when coming onto boost- NO droning. No stepdowns inside muffler, 3" all the way. In top condition but kinda dirty, just needs a little clean. Performance and comfort, yes. Price $110 Pickup Parramatta NSW Ron 0416424446

Lol at coke can. Havent had coke in ages mate. Might try that trick though. Dont know about surge, yeah happens with full tank n yes when you boot it after downshifts. BUT, if you wait a second or two after downshifting or if you very gently stab the pedal after thge downshift, it doesnt happen or you dont feel as much- depends on the load and time/nature of stabbing the pedal. Tune related- yeh Yavuz said nistune has inbuilt filters to iron this out/tune around it but powerfc doesnt have anything they could adjust as they've fine tuned it a fair bit

Thats what I told them but they have been through the tune thrice and massaged it as best as they could, Yavuz said theres not much else they could do to the tune to make it even better.

My problem is funny because it happens kinda off boost as well ( when theres no BOV recirc), say shifting from 3rd to 2nd at 3000rpms you get this bogging but milder, the more load/boost its under, the more pronounced- but why only during downshifts..?

Nope u didnt get me, I meant as in stock setup with afm behind air filter, when the bov recircs into the turbo, the afm isnt measuring this air ( its only measuring air sucked thru the filter) so really the turbo is pumping more air than measured= lean :\

Afm in cooler pipe means high boost blown thru afm = bad/damaging? Or isnt it. One other thing is, during the BOV recirculation into the turbo, the afm hasnt measured this air hence the turbo is pumping more air into the motor than measured thru afm/intake = lean/danger?

Hey guys, hope you all having a good weekend, well heres my problem again which I mentioned in my past thread 'Restriction in Exhaust' but decided to create a new specific thread for it. R34GTT running Precision 5558 @22psi on 98 with support mods, Z32 afm, Power FC, EWG off housing, stock plumbed back BOV etc. Problem- bogging down big time down and losing 50-60% power for 3-5 seconds when downshifting ONLY. Doesnt happen in regular driving, boosting, upshifts. Didnt happen at all with my previous Nistune, exact same setup all else. Diagnosis- went for a drive with Yavuz the tuner and he finally managed to detect what is causing it- the map tracer in the power fc commander drops 5-6 cells down during this period. He said the Z32 during this point is seeing a big voltage drop or something I dunno, and hence metering the wrong or extra airflow to the ecu which is dumping extra fuel and/or retarding timing since its thinking its seeing 15psi instead of 5psi. Couldnt be a faulty Z32 since its only under this specific condition it happens and it didnt happen with Nistune/ same all else. He said Nistune has the filters to iron this out, whatever he meant, and they have been through my current Pfc tune three times and absolutely confident that it cannot be made better - and I agree, from driving experience, apart from this downshift issue. The only other possibility according to Yavuz is the famous n dreaded BOV recirculation issue blowing air at the afm. He had a look at my piping and said the entry angle of my bov return into the intake isnt optimal at 90 degrees and should be pointed back at and closer to the turbo intake. Have attached pics here, what do you guys think? Scotty once mentioned it could be the CAS too, and I think he could be right also. Dont have one to try though.. Another thing with the Gizzmo IBC-R ebc I installed, boost goes up, down, up, down, up, down everytime - what causes that- have no leaks and gain is low around 10 with duty at 58, overboost at 22.5psi. Goes from 22-18/16psi back n forth.

Buy buy hhhhhhh

As above

Need this gone..bump..! Only $550 for a 290rwkw R34 Nistuned ECU

Fresh Bump!

Learnt that the R34 ecu pinouts is totally different to the R33 and is very hard to find on net. The tacho signal seems to be pin5 which Im sure is the black/white striped wire. Can anyone confirm? Wires held up too tight and dont wana pull and damage any cables..
