QWK32 - i have a copy of the software yes..

mods are

HKS GTR-s

front mount

3" exhaust

greddy boost controller

the guy before me had haltech on it but i saw alot of advantages to the nistune so i went that way..

i have acopy of all the base maps aswell, is there some things i can do to that to help things?

i also have a apexi turbo timer which outputs the AFR'S, as soon as you touch the accelerator at 60k's it goes from 14.5 to 10.5 or even 10.0 sometimes..

thanks again

don't pay any attention to the apexi timer reading. the stock narrowband O2 sensor can't be trusted with any value apart from ~14.7, even then i'd doubt its accuracy. if your getting a reading in the 10's on the pen timer, it could really be a value anywhere from say 10-13.

what tune do you currently have on the ecu, stock maps? on the stock maps it will run rich once on boost even with the GT-RS. i suppose you could take a bit out of the high rpm, high load part of the fuel table, but without getting a wideband O2 sensor to check it you wouldn't know if you've taken too much out. do you have access to a wideband O2 sensor?

also i'd be interested to see if you coming close to the limits of the stock AFM, what boost are you running? link up to the ecu with the software and open the timing map, then watch the map tracer to see how close to the right hand side of the map it goes when you rev it out under load. ideally you don't want it to hit the last row of cells. also check the fuel map, it has a smaller load scale than the timing map so you can run off the edge earlier than you will on the timing map.

flippin' heck

i thought you could get Nisstune's for all Stags. i was looking forward to putting one in my S1 later this year :P

you can, but you have to be willing to chop and rewire your ecu loom to a Z32 ecu plug so you can use a Z32 ecu.

don't know if this would work, just an idea. but could you replace the stagea engine loom with a late model R33 engine loom? engines are the same so electrical plugs should be the same. probably have to splice in a few wires that go to other areas of the car, should be an issue though. then you could easily run a Z32 Nistune ecu without having to hackup, identify, and rewire the stagea loom.

i have stock maps loaded, no tune has been done since the board was fitted... don't have access to wideband.

using stock afm atm but i have a z32 ready to go (wiring is all sorted just needs to be plugged in). next part sounds like too much effort!! lol

i have no idea once it comes to the tuning side of things so yeah, i friend works at a workshop that has just signed up with nistune so i might just get them to tune it for me.

I am trying to find. Who in sydney does nistunes and has had heaps of expirence and has a 4wd dyno

Someone has recommended CRD for tuning. And I do believe they have a 'special' offer in their business thread on these forums.

But I've never done this before so....

Unigroup.

Either get them to drop the front driveshaft or drop it yourself.

If they are happy to let it on the dyno with the little green plug pulled then you can go that way.

I would strongly suggest using them.

i want unigroup to do it but i am a fusy prick and i want it done in 4wd. Unigroup know envy performance and they have a 4wd dyno and sometimes use it so i am trying to see what i can hook up.

What difference does a 4WD dyno make? Nearly 100% of the time your car peddles around on the rear wheels.

If Yavuz uses the Envy dyno it will be for cars that does allow easy 2WD mode.

Best bet is to give them a call and see what they say.

I paid extra for a 4wd dyno once but then thought why did I do that ? There is no point whatsoever fussy or not. Just drop the front driveshaft and pull the fuse and the 2wd dyno will do just as well. The only difference is you will get a rwd power figure but so what ? The tune and output is the same. You can always look out for a dyno day on a 4wd if you must have the awd figure.

...and it will be within a bees wang of being the same anyway.

not quite true.

my car dyno'd at 210rwkw with the front shaft dropped on a 2WD dyno.

on an AWD dyno it dyno'd at 178awkw - same car - same mods - same boost.

different dyno, yes, but i doubt it would account for a diffence of some 30+kw. lots of mechanical loss of power in the drivetrain. does that mean the car would go harder in 2WD mode? i have no idea.....but the dyno doesnt lie...much. heheh.

(out of interest, that was done on an eManage Ultimate. i now have a Nistune that i'll be throwing in and getting retuned. Mod's won't have changed at all, so it will be verrrrry interesting to see what figures they can pull out of the Nistune vs the Emanage)

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      By BaronOBeefdip · Posted

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.

      Thanks for that, hadn’t used my brain enough to think about that.

      R33 GTR running -9 with no tune

      By MBS206 · Posted

      Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.

      You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
