Got a nistune comp going in my 31 and it'll be on the dyno later this week. Does any one know if it possible to give it two separate tunings and how hard it is to switch between? ie: can i tune it for high performance on one setting and max economy on another, and is it as simple as flicking a switch while i'm driving or when the car is off? or would i need a controller to plug in or my laptop? I'm sure this is covered somewhere, couldn't find it at a glance so can any one tell me or point me in the right direction? cheers.

IMO there's no need, the high load high rpm cells will be right for the high performance and the low load low rpm cells will be right for max economy. You choose what you get via the right foot!

If you wanted two different tunes you'd have to get the nistune software and a consult cable and install the tune each time you wanted to change.

Once you get your final tune I can probably help you on switching tunes.

The ECU can be setup with a security feature or a different tunes for different fuel etc.

Let me know what the part number is and I'll double check.

I can run up to 4 different tunes in the R31 ECU and most switchable on the fly.

Kind regards

im always putting 98octane fuel in it any nothing else. I work at a servo so it's never out of my way to get it. So i don't want different tunes for different fuels. Is it worthwhile trying to tune it for better economy or should i just drive with a lighter foot?

I think it largely depends on who has tuned it.

but still ends up back with the Drivers ability to control the foot as well !!

As you have stated, there is no need.

A good tune will be economic when you are light on the throttle and have the power when you boot it.

Running multiple tunes would suit running different fuels (as mentioned above) or in a dedicated track car where the team may want to switch between tunes for different tracks/setups.

Stick the the one tune, goodluck with it :D

If boost is held constant then the best performance tune and the best economy tune will be the same.

Down low you'll have as much timing and as lean as it can handle eg off boost and with O2 feedback, up high you'll spend 2% of the time there if it is daily driven so it doesn't really matter how it is tuned.

Ask nistune themselves who they recommend to tune it.

there is no point, it should be tuned for maximum economy and best power in the one tune. the only reason to have multiple tunes is fuel changes. Nistune cant run multiple maps.

cheers for all the replies fulla's. It makes it easier on me now. Just gotta make sure i take it easy now then.

Nick is busting out some pretty good tunes lately... As everyone else said there is no real difference between a good power/economy tune as the afr's are the same for both (or there abouts).

The best way would be to install a electronic boost controller with hi/low boost switch... low boost is eco mode, hi boost power mode.

Power= air + fuel. Less power used = less fuel used- so just don't drive so hard.

Or install a throttle stop... ha h ah ha.

Cheers

oops, i didn't mean the throttle stop. i meant how hard is it to put in the electronic boost controller. or how much would that cost?

It's probably one hours labour for Marty to install it. Electronic boost controllers start around $400.

I have a dual stage boost contoller in mine with 7psi & 17psi for the exact reason as you want but its not needed as everyone has said before me. tunes it as high as you can go with boost/economy and use your right foot as the tuner.

i learnt the hard way as my switch is alway set to high now...

    • Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.
    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
