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?

    • Working through possible solutions of converting my mechanical speedo.    Anyone know what type of speedo sensor the factory r34 gtr getrag has ? what the output is ? I assume its not a VSS and more a voltage like earlier speedo sensors ? Can an ECU read it ?  
    • roof rail delete used to be a thing, they were made locally for a while too
    • I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps  
    • According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car. 
    • It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
