Hi all

Having owned the Evo for just over a year now, I thought it was time to try the Snow mode for real in preparation for a planned trip to the snow in a few weeks.

I went up Mt Donna Buang (a recent SAU cruise also went up there) after lunch in Healesville yesterday.

Despite having to pay to go up the mountain at this time of year and having no parking at the last car park before the summit, we had a great time. Took a few pics in one of the lower carparks as all the roads were pretty well salted.

Having only used Snow mode on the DECA skid pan in the wet to any benefit, I was keen to see what it can do and I must admit although I was far from driving hard, it felt a lot more balanced than any other mode.

So to conclude, yes it feels like it makes a difference and gave me a good opportunity for some pics :thumbsup:

Emsta - the ACD settings (Tarmac, Gravel, Snow) adjust the way the car behaves depending on the surface you are on.

By telling the car you are on snow, it limits throttle response and forces a tendancy to understeer when pushed. Basically meaning you just continue to drive the car as you would normally - it makes all the adjustments for the change in surface.

Cheaters.

I drove Beefy's EVO9 on the weekend, very nice i like it. Very punchy/responsive, but lacks top end - but that is to be expected being stock... didn't get a chance to throw it around any corners but it felt responsive steering wise as well.

After losing my last reply to a database error!

Thanks all, I had a lot of fun all be it driving quite cautiously due to the weather and having the g/f on board. There is a taboggan run at the top but couldnt get a park so had to come back down unfortunately.

Emsta - As James says.

My understanding is the Tarmac, Gravel, Snow splits the bias to front and rear wheel drive percentage. Snow 50/50, Gravel 60/40, Tarmac 70/30 (rear/front). There are more agressive mods out there to split it further such as MOTEC and there is a Ralliart ACD controller also.

:D

;)

ratio is always 50:50, acd just controls release time of diff, tarmac - fast / gravel - medium / snow - slowest

ah...so its similar to the Dynamic stability control that we find on BMWs and alike and also like the GTR's, when the front wheels lose traction, the rears hold the traction?

I'm pretty sure its not,

Its the actual torque transfer to individual wheels and its only available from R33Gtr V-spec onward. I don't know much about the Dynamic Stability control, is it a bit like the what they call Brake Distribution Force something?

    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around with a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
    • Yep, this bit another local owner. I caught it before putting the transmission back into the car, what I noticed was the pressure plate fingers weren't flat and even. It's more obvious with the pull style clutch because the throwout bearing ring was visibly not flat once everything is put together. Nismo should really update their instructions to call out this specific detail. I'm not even sure the clutch as-shipped orients everything properly.
    • It ended up being that orientation of the float hub in relation to the clutch disk, when I installed it, I heard a loud click and being stupid, I decided to not take it a part and check it. The hub didn't properly align with the clutch disk and was causing the issue. Definitely an odd one! Dahtone Racing was able to fix me right up, stand up blokes!      
    • Right, but I'm saying on the stock ECU measured airmass from the MAF is no higher than stock. So it's accounting for the higher flow rate iso-manifold pressure. You just have to keep turning down the boost until you're within the stock tune's load scale. If you run off the end there's no telling what will happen. This does mean there's zero benefit to the turbos you're running vs stock, if anything it's just a straight downgrade because the transient response is worse, you don't even get the ECU's boost solenoid helping to pull the wastegate closed during initial spool, and peak power is only whatever the factory map can give you before you hit the R&R corner. On a -9 I would bet that you would have to change out the wastegate spring once you have a real ECU and you're tuning it for real. I'm not saying this is a remotely ideal state of affairs, it's just a way to keep it driveable until you can get a proper tune done.
