Hey guys,

Got a r33 which I've stripped down n put some basic bolt on mods to, greddy copy plenum, garret 35r ext gate, running a nistune chipped ecu (rb20?) FMIC n all the rest of the usual goods to support injectors, pump n z32 afm ect.

Have started the engine (with rb25 ecu and stock fuel system to check it runs and for leaks ect before it goes on the dyno n costs me a shitload in leak repairs ect, all was fine) and now have installed the injectors, afm and pump to the motor, i would like to get a few people's thoughts on A FEW WORKSHOPS/TUNERS that tune nistune, thanks guys

Gav.

Id ditch the nistune for the 33 mate my car never ran quite perfect with it plus using the RB20 ecu stops you using VCT from memory which you will want if ya running a GT35. Mine was a Z32 ECU. Id recommend picking up a power fc on the cheap if you can. If you got a bit of coin to splash out get a link G4 my car ran awesome with the link. Tuner I would recommend is unigroup engineering at Girraween :)

Cheers guys,

Interesting, I'm pretty clueless in regards to the ecu Side of things so thought I'd come on here n ask,

Don't you lose VCT anyway once cams/vernier gears are installed tho?

(Which I had forgot to list, my f**k up lol) I've heard good reviews about yavuz at UNI group.

If I was to run a stock engine with the rb20 ecu how would one wire the switch?

Thanks

Should have kept the VCT...

Nistune is fine if if you want something a bit cheaper. But you have a to source an RB20 ECU and then put a Nistune board in it. Not hard. As you don't have VCT anymore you don't need a VCT switch or a Z32 ECU.

Power FC's are good for people who just want a tuneable ECU that is plug and play.

Link ECU = Stupidly awesome ECU with so many features (depending on which type you go with). But the cost tag is up there for a lot of people. They do plug and play models as well as a full wire in. Full wire in is always a better install as you get rid of the shitty 20 year old wiring loom.

I'm not from NSW, but JEM is quite good?

@ kitto

Yeah I got my hands on a old mates rb20 ecu with the board for next to nothing hey, I suppose if I had my time again is go a pfc or link, I might go see how it goes when I speak to the tuner n get there opinion also before I make the call hey, I appreciate the help guys, might find myself on here a bit more, lots of good info n good people on here..

The g4 is a sweet bit of kit tho, friends got one on his 32, goes like a rocket!

@ micko

As it's a toy not my daily + it's just a bit of fun I'd like to keep it lower the better but obviously you get what you pay for,

Not poncams, there kelford? If that's how u spell it..

Yep both intake n exhaust are vernier gears.

Fair call mate I understand :) oh yeah kelford cams. Another option is adaptronic ecu great value for money and an Aussie product I believe. Having a good ecu is the icing on the cake man just seems crazy as sounds like you've spent decent coin on the rest of your setup then not going for a decent computer :) sometimes not skimping out in the 1st place can be cheaper than doing it twice when ya car doesn't run how you'd expect after you outlay good dollars. I dont know what a nistune upgrade is worth these days but for a few hunge more up front the outcome will be much better.

Yeah it makes sense for sure, better have a good think about what to do, which ecu to go with, probs pop into one or two of the workshops n have a chat, see what the tuners seem to like working with n get a few tips n whatnot before crunch time on the rollers,

Can't wait to take it out for a spin tho, long time coming...

Toshi does good/cheap basic tunes. From my own experience I could've saved myself alot of time and money buy taking it to a workshop (JEM was who I eventually used). I don't want to delve into it too much but basically what Toshi told me was my issue (air leak/blocked IACV/02 Sensor/AFM) turned out to be the injector latency weren't set-up correctly. Cost me 2 retunes, and over $300 in diagnosing from Toshi himself. Rather dissappointed in my experience overall. Forked out another $1200 with JEM and have the figures to show. Smiles everytime I start her up now.

Just my 2c...

JEM, Unigroup, CRD, DVS JEZ.... Plenty of good tuners around!

Personally i use JEM but there are a LOT of good results and examples from the other guys floating around SAU :)

turned out to be the injector latency weren't set-up correctly....

But... This is the basic first step of tuning with larger injectors... Get the sucker idling and free revving nicely, then start driving, or am I missing something?

    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
    • What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
