"The decision taken by Subaru Japan was to install the manual version of the intercooling system. This it was felt would be acceptable given the increase in intercooler efficiency."

Refering to that part of the answer, the IM guy is stating for UK models as the Japanese market STi and STi Spec C definately has auto IC sprays.

I don't suppose you know how to get the Subaru part number for the Japanese STI or Spec C IC switch. I know that the ECU has the wire out as that is where the SUMO Power switch plugs in.

Is it ok to feel a tiny bit smug now, or are we still supposed to admit that we really *are* pussies who never drive our cars hard enough to activate the [non existent] auto i/c spray?

Cheers to revitt for coming up with the answer.

i have been told that on the STi8 the auto spray is controlled by a seperate controller outside the ECU, that would need input from the ECU or its sensors. Still waiting on full info on this right now so it may be wrong.

Could your Auto IC controller just be taking boost output from the ECU and using that as a trigger?

I dont know if the switches are the same on the STi7 and STi8, but you can buy STi7 switches here

I would be surprised if Mike Wood is wrong, but clearly someone within the oficial IM/Prodrive partnership is wrong because they contradict each other.

Am I missing something here, REVITT (Mike) gets a letter from Subaru Technical that clearly states that the IC is manual and people are still arguing about this

johnfelstead

Mike Wood works for Prodrive and develops the STi8 PPP, he should know what this car does. The man from Subaru UK is contradicting what Mike wood is saying, so one of them has this wrong.

Until that confusion is cleared up i would say we dont know the answer.

Why dont you contact this guy at Subaru UK again and tell him his partner at Prodrive disagrees with his statement. Surely we cant have two oficial bodies telling us contradictory information, that slooks pretty crap and doesnt give us an answer.

revitt

John,

I have already drafted another letter to Subaru about this and will get it into tonights post, should I name Mike Wood or just say a Prodrive employee.

johnfelstead

Why not say Mike Wood? Saying who told you this is going to speed things up. Mike is the main man at Prodrive on the STi PPP program, they should know who he is!

revitt

Thanks John,

I am always cautions about naming people on public bulletin boards in case they are not in an official position to be making those statements.

I would hate to get someone into trouble who is after all just trying to help us.

But the letter is now in the post, last time there was a 2 day turn around so I should have a response Wednesday.

johnfelstead

Should be an interesting response. Mike is quite open on here so i cant see any issues with his name being used. He is usually right when it comes to things like this but you would also expect the technical specialist at the importers to be right too. Either way, we hopefully can clear this confusion up and get the real answer soon.

As to Arron, the guy is an animal, i would have expected him to have met the required parameters by now.

If it's manual only then i'm phoning up my dealer to check out a leak in the system as i've hit the button 4x max and i've just refilled... then again i never checked if it was full when the car was delivered.

... hey maybe the kids are drinking it now it's summer ... they tell me it gets real hot in the boot

Guys thiers no argument here! New STi8 is manual, mine is.. the car i test drove is, the car in the showroom is and the bloody thing makes my daughter ask " what was that dad in the boot" every time i press the damn thing, Obviously whilst trying to avoid the scenary in the process! Problem is; when me and the missus are having a drive about she knows i'm going to give it some every time i stab the thing... she's clever ar lass like that!

I have PPP on my Sti8. It has just been fitted, so where I can it has been driven hard to see if water is used. The bottle has remained at the same level thorughout, so I can only assume that mine is manual regardless of PPP. Or am I just not driving hard enough !?

Steve

johnfelstead

Yes there is.

Dazza's-STi

PPP nothing to do with Water spray!

Mines got the PPP pack, infact i've just picked up the bits they took off, and the don't include a maual water spray!

Idea!

try velcro water bottle to roof of car, use syphoning technique "ask local petrol pinching ****** for advice if not sure" before setting of on you fav B road!

Dazza

johnfelstead

eh? the Auto fuction doesnt mean you remove the manual switch. If it is there, it will be the ECU that is controling it.

ProperCharlie

Interesting link JF - the fact that you can buy two types of switches; the manual one which is the one we see on the STi7&8, and another type of switch which does not cause the water to spray out when you push it, but instead turns on or off the auto function - this implies to me that the manual switch is for the manual only system that the majority of people seem to believe is what the uk cars have, and the other switch is for the (JSDM?) auto cars.

apologies for the length of that sentence

johnfelstead

i know what you meant.

My STi5 RA has both switches, it does seem rather strange that they deleted the Auto switch on the UK car yet it still has an auto fuction allegedly, yet the japanese spec car has both switches still? IM cant be that tight can they?

forest172

filled mine to the top the other day, and the outside temp gauge read 29c, and I did give it a quite abit of 1st and 2nd gear hammer.

I then checked the tank and yes it had gone down an inch!

pbee

Would it be possible that left over stock of ic water coolers from the sti 7 was used on the first few sti 8's in production to use them up, so these lucky few would have automatics. Could explain why the prodrive cars would have autos as they would probably be some of the first into the uk ??. Then the rest would be manual.

just a wild sta in the dark, dont know how efficient these car manufacturing places are, they would be unlikely to skip a load of parts if it could be fitted to the new model.

Animal......Moi?????
I dont beieve you have ever been in a car with me John
Gearbox doesnt like reverse on my bus at the moment????

johnfelstead

why do you think that is?

Get some decent oil in the box Arron, the subaru stuff isnt the best. It makes a BIG diference on cars that are driven hard.

ARRON BIRD

Its going in next week mate.
I thought it might be clutch but I dont do mechanics!!!!

johnfelstead

hope its nothing major.
You dont do mechanics but you do keep them busy.

philgr

Come on guys lets not let this thread die,

is there any more feedback??

what does mike wood (prodrive)think?

I am concidering adding the auto waterspray by using my SECS unit and the replacment auto swich and an interposing relay, should be a doddle to do, just got to find the time to do the job.

I have sent a snail mail message to the General Manager - Technical Services Subaru (UK) Limited and am awaiting his reply, again. Last time I had a reply in two days but that meant I should have had a reply today. I am hoping that there is some serious correspondence going on between Prodrive, Subaru UK and Subaru Japan.

I will give then till Monday then contact them again if I haven't heard by them. Don’t worry I will post the result when I finally get it.

johnfelstead

I had a look over an STi7 Japanese spec car yesterday, just to check i wasnt going mad. That had a manual and auto dash switch, just as mine does.

So why would the japanese spec car have this and the UK not, if the UK was auto functioning too? It doesnt make any sense to me?

revitt

I have been thinking about this and I think the issue could run and run. Remember this only applies to UK STI Impreza’s with a single IC Dash Switch

So I am going to outline a couple of synopsis and then I ask you to post the relevant information so I can compile a set of statistics for our own and Subaru’s benefit and to assist Subaru in getting to the bottom of this.

1. The IC is fully manual as stated by Subaru UK. (Unlikely as so many cars are using water)

2. Some STI’s have an automatic system and some are fully manual. (Unlikely, what is the sense in that)

3. The IC is an always on automatic system, but is faulty on some cars. (Unlikely because of the number of cars not using water)

4. The IC is an always on automatic system, but the parameters are set so high that you only start using water after PPP which lowers the parameters. (This is, I hope, the most likely synopsis)

Now that I have prepared a set of synopsis, let me know if you can think of any constructive omissions, I need to gather some statistics to determine which of the above is the most likely.

SO PLEASE POST

1. Do you use water?
2. Have you had PPP fitted?
3. Are you an aggressive or light driver? (i.e. if the parameters are set high are you likely to trigger them)

I will start the ball rolling

1. Don’t use water
2. Haven’t had PPP fitted, yet
3. I am an aggressive driver, full throttle, max boost, max revs.

Thanks

Mike.

I have tried to read all these pages, so sorry If I have missed the point.
I have just got the owners manual out for my STi7 Type UK and it says:-
"water is sprayed for approximately 2 seconds every time the switch is pressed and then released"
It also says in a CAUTION box
"do not press the swith when the warning light is illuminated. If the switch is kept pressed when the tank is short of water, the water pump motor could overheat"

BASHER

Oops, hit the wrong button.

There is no mention anywhere in the manual about this system being automatic, and I have never seen my warning light come on, so assume from that, that the water bottle still has enough in it. I have had this car since Nov 2002 and have not topped up the bottle once.
So the system (on my car at least) is fully manual or I drive like a woman all the time. lol
