intelligent mode

i had my car in intelligent mode and noticed a green triangle flashing on occasion anybody know what this is?

ahhh great thanks

I call it Mr McGoo mode... I'm in it 99% of time, whenthe wife hears the Beep when you swap it to Sport or sport# my wife look at m with those eyes!!!!!!


day to da driving its fine.

SPORT.. good on twisties as it has good acceleration pick up responce etc.

SPORT#.. awesome for over taking and smoking Audis.. and boy racer Corsas

I keep mine in sport, looking at the standard ecu maps this is the most linear relationship between throttle butterfly and pedal. Imode basically has more pedal travel for butterfly opening at the beginning of it's travel and sport # the reverse for precise control at the end of it's travel for track work etc. Put the pedal to the floor and it doesn't make a bit of difference what mode you are in you still get 100% throttle butterfly opening (and of course boost targets etc are all the same for each mode).

I dont bother with any mode other than Sport#. pointless button in my opinion unless your on race rom and switch maps for different fuels I.E methanol Map

I'm with Rob, S# 90% of the time, Sport if I am in traffic, can't be bothered pushing on or want a little more comfort / smoothness driving in stop / start .....

Of course my sport is the old S# and S# is now .... better


For race rom aren't there options for map switch, e.g. press heated rear window button while starting or something?
For a meths map you are going to be in that map for a tank full of fuel !

Sport until warm, then sport# for me
Intelligent mode - waste of time
Even on my old 05STI which was mapped by Mr Forrest I never went near the low boost switchable setting

I'd love to get Andy to remap the 330S, but fear prevents me from doing so.

I agree with Nick - I mean Rob !
I heard the S map was over-fuelling so the s# map so should give better economy as well as better response.

Stan - once remapped over fuelling on S mode should be sorted! Ask Martyn perhaps?

Urban - if engine fails are caused by ECU Map issues ( on the weak pistons, head gaskets etc. ) then a custom map will reduce the potential failure. I know mine was kept below the critical point for BHP for this very reason by that nice Mr. Forrest - kept a bit rich and not on thelimit ignition advance, and a bit ofallowance for the odd dodgy fuel!!!
As said elsewhere on here, we hear of very few / no engine failures for the custom remap cars ( Rob's was fuel quality problem ).


Of course get pistons / forged build and go for it with peace of mind!!!

I'm not sure how that can be on a standard car? The fuel, ignition, boost maps etc are all the same for each mode. The only change is the throttle pedal to throttle butterfly relationship...

I'll post up the throttle graphs later if i get chance to see the difference.

With RaceRom tho you can have complete new fuel/boost maps etc. When i do get my remapped i'm going for i-mode as 95ron map with lower than standard boost...

Finally got round to looking at the si drive maps. Looking at the values in the throttle map then at the target boost map, i-mode only targets peak boost (2.027 bar absolute) at 6000 rpm, from 2800-5200rpm i-mode is some 0.2-0.3bar lower than sport and sport sharp. I.e the mid range will feel 'weaker'.

Below are the maps, had to squish them a bit to fit the screen (from top to bottom i-mode, sport and sport sharp):



Target boost map below too (with fuel map aswell):

Wow, those pics are poor quality. Sorry

does 'I' mode differ when on a 330s?

I don't have access to the 330s map (locked by EcuTek), however some have gained access to the rom and they seemed to think the changes across all the tables are very limited. So I'd guess the throttle maps would not be significantly changed. However thats just info I've read from forums so could be utter rubbish (like what I generally post )

Ps slightly off topic but an old and interesting thread from the US on the changes to the ecu map that Subaru issued...

Crawford NASOIC Tech Report

Brilliant source of info, I'd be interested to see the 330's table's overlayed onto the std 08 sti, to start to piece together why it is that the ppp & 330's versions suffer so many engine failures. I have suspicions that it's to lean while coming onto boost. so whilst its under 100% load to get the car going it's already starting to det its heart out

We need a std 08, and 330S on the rollers to get bhp/lb ft and AFR/Boost pressure curves to answer that one Rob, the Crawford report does start out wrong as in missing changes and making assumptions... not got to end yet tho'!
IIRC hitting red line / rev limit and the Subaru safety strategy for this ( reduce fuel NOT cut all fuel! ) led to weak mixtures at high load which led to high combustion chamber temps & pressures ( and possibly det but not a given ) and that led to piston ring land failures, also could explain crank issues with the shock loadings on bearings/ oil film.


Worringly, both dealers I got hatch STi's off stated, the latter one very forcefully / categorically that the PPP ECU exchange / map and the 330S factory map deal with all known issues of engine / piston failure, so much so they wouldn't give me a statement they had done the reflash on the 330S nor the ECU code ref from the tech service bulletin / reflash upgrade bulletin so I could check ECU code / microcode / firmware with Prodrive or IM.


Either they believed what they were told ( by IM, Prodrive etc. ) or were blaise on the potential failure risk.


Still not sure on proportion of 330S std or PPP ECU cars that have suffered failure vs std STi's.

I contacted a certain well known person in Prodrive with regards to versions of the 330S map.

He told me that there was only the one and no reflash was necessary or available.

Interesting..

The dealer at first service ( or maybe the oil change at 5000 miles I wanted them to do ) had my job slip written on with a service check which he said was ECU reflash.

But when I collected the car and asked if he had done the reflash as per the bulletin listed on the paperwork he said no it didn't need it.


So maybe they were just confused about STi's and 330S?

From what I've heard there is only one 330s map.

The Crawford tech thread I posted didn't show their tech department in the best light, the most accurate info came from teacups... who is well known in the opensource community. Think he now works for Cobb (but could be thinking of the wrong guy). A Crawford guy did also say on that thread their take on the ringland failures was oil in the intake, so fit a catch can and all solved It was an old thread, not sure if they still hold that belief.

Back to the original topic... I'm going to do some logs with DeltaDash this weekend to see the boost profiles for each si mode, need an LC1 to log wideband tho... May get one ordered.

Ps I'm still on the original map, not the updated (3 years old, 17k miles)

theoretically Oil in the induction system will lower the octane rating of the fuel quite substantially, so under heavy load & boost conditions it will make the engine more susceptible to detonation..

Can't argue with that, but for Crawford to say the engine problem is purely down to this seems a little optimistic.

May fit a catch can anyway when/if i get round to doing a CAI.
