Hiya chaps

right then i have a boost controller that i need to install eventually

thing is - i have no idea how

its a nice simple one - 3 wires - red/black/yellow

red - power
black - earth
yellow - errrr its yellow does that help

now speaking to some people about this

they reckon the yellow ones does something to the boost duty selaniod ?

now i was lost at this point

does the wire go to the ECU , does it piggy back something else or what !?!?!

any help would me much appreciated

What type is it?

Ok way too little info. You said boost controller but most boost controler I have ever seen DO not hook to any electrical components besides the batter and thats only Electronic boost controllers. Tell us which one you have and we may be able to offer help. On your basic boost controllers you will have a power, ground, and a couple wires(maybe 1) going from the soleniod to the actual controller that goes in the cabin and controls your boost settings and when the soleniod pressurizes or de-pressurizes. But none of them should go to the ecu anywhere unless your using a Greddy E01 and then the wires go from the E01 to the emanage and then to the ECU . If its a MBC then what are you doing with wires they dont need them. ~

right then , i will try again - wrote a good reply and the net went down

like i said - boost controller is a very basic one - from what im told it only turns boost DOWN

its just a little dial and 3 wires

i spoke to a UK tuner and all he said was

Hi grinder
the yellow wire goes to the blue/white wire that goes to the duty solenoid
Cheers

which doesnt really help me - although it might make sense to you guys !

now that sounds about right - so how would you wire this up ?

i can get you a picture - would that help - although it would only be monday before i could post it

sorry for being vague - but a firend took it out of a car that we parted and didnt write down where the wires went

Well I have never heard of a boost controler that can turn down the boost only. THat would be called a wastegate. As far as equipment we would have to know what yoru using to be any help. I assume that you have one vacuum line going into this solenoid from the compressor housing and then one vacuum line should go out the soleniod and into the wastegate. Then you would hook your power to any power source(a 12 v fuse under the engine bay) the ground to any grounding point in the engine bay and that last wire if it were a normal mbc to the controller that came with the solenoid to control how much boost you are running. I must warn you though I have never seen a boost controler that can make you run less boost then your car naturally makes. The only way I have seen people turn down boost is by adjusting an adjustable external wastegate or porting out the internal wastegate. THats it.

Manual boost controllers should have any wiring involved. My guess is:
red= 12v Constant
yellow= 12v ignition
black= ground

I may have red and yellow switched around but you should only have to see if the boost controller holds it's memory settings.

bigturbo

Yeah but dont those usually come of the controller itself and the soleniod just has ground and power that run to the controller???? Thats why i ask for more info Are the wires coming off the control unit or the soleniod?

ilike2eatricers

Yea I assumed he was talking about the harness wires that come off the actual controller. He was told the yellow wire may be for the solenoid but I think they are mistaken. If you had a 12v ignition wire without a 12v constant the boost controller would never hold any of the settings.

elfking

Most every stereo I hooked up was:
RED = ACC (12v switched.)
YELLOW = 12V+ Battery/Memory (Stays on a fused 12v connection to you're battery directly.)
BLACK = Almost always ground, unless someones been playing funny tricks on you.

This is pretty much a standard to my understanding.

I HAVE seen it the above way though on some older stuff. Most stuff I have ever delth with is what I said above...

If you haven't connected the solonid and its expected to be one of those 3 wires, then I would try Yellow. You would think this solonoid would have something on the other end of it to tell what color went where? Something sounds fishy.....

dr.jones63

What brand and model? Go to their website and download the instructions.

If it's a STOLEN controller that some idiot jacked out of a car...........your missing the solenoid valve and the pressure sensor, good luck.

grinder

blimey - its gotten all exciting in here !

its not a STOLEN controller - me and a friend broke a TII and he removed it for me

right then - i have a pic ( at home ) - so i will get that sorted in the next few days

so what i have ( had a look closely at it ) - its a dial with 3 wires coming off it - that go into a little box ( with no writing on it ) - and the yellow wire comes from that

like i said in a post up there ^ - one of the people i spoke to - says it goes to the duty selanoid ( it doesnt come with one )

from what im lead to believe ( this is a vague idea ) - your boost selanoid tells the engine what you are boosting at - so this dial can turn the boost down - so i would assume that it must interupt the signal ?? ( sounds about right in my eyes )

the boost selanoid must tell the ECU what fuel air it needs and the such like - so this unit must bebale to turn down those values so that you dont boost so high

when my friend had the same unit - he was running 12 psi - but with this fitted he could turn the boost down to about 7 psi for a running on the motorway and around town ( and he has no idea where his was fitted either )

i think i will have to put the pics up - it may make it easier - i looked all round google to find a simialir pic of one , but i have couldnt find one

thanks for all your help - but i dont think im onto a winner with this one

well the gray box is def a soleniod now is that other piece of equipment just a gauge because if so then you are missing the controler itself. If not and that peice of equiment that looks like a guage(glare cant read the face) is the controler then one would have to think it is conventional wiring as a radio is set up as explaned above. The black is def a ground, red is the acc 112 v with switch, and yellow is the memory and should go straight to the battery without a switch but use a fuse.

The black is def a ground, red is the acc 12 v with switch(use ignition wire that runs to the main fuse panel under hood), and yellow is the memory and should go straight to the battery without a switch but use a fuse. None of that should go to the ecu. What concerns me about this setup is that there seems to be no vacuum lines coming out of it. Are they just not pictured?? Because every boost controler I have ever seen uses a vacuum line coming from the turbo compressor and to the wastegate to control boost. And the reason for this is that its a mechanical operated wastegate and the only thing that the ecu can control is timing and fuel, thats how it limits boost if you go beyond the stock level is cut fuel. So even if your boost controler is hooked up to the ecu it still would not be able to stop the wastegate from opening. If you understand that then a manual or electronic boost controller should have vacuum lines. So are the metal or plastic nipples for the vacuum lines on one side of the gray box not in the pics??

grinder

thanks for the reply !

the grey box has nothing on it at all - the round thing is just a dial - nothing more nothing less

thats all that was in the car when my mate took it out - and it was a working unit !

i know what you mean about the yellow wire regaring the perm live - i think they just used a yellow wire thats all !

from what i assume ( he says !! ) - it looks like you can control some sort of voltage with this system - now in the 4 post - some UK Tuner told me that the yellow goes to the duty selanoid - now does that make sense to anyone ??

does the duty selanoid tell the ecu what fuel / air to use - so could this unit tell it to use less - therefore less boost ??

im not sure what else i can add to this - i have no idea - dont you just hate it when someone gives you bits - and doesnt tell you where it all went !!

the only thing i know for a fact is that the engine was removed by the tuner - and when my mate took the controller out - the yellow wire was already cut

oohhh this is really annoying - oh well - lets see if anyone else can shed some light on this

i cant believe in the whole of the USA - no one has a boost controller like this one ??

BIGTURBO :

you mentioned

"

"

in a previous post - does this still stand true with the pics supplied ???

bigturbo

Well it should as any electronic device will need two things, power and ground which universally are the red and black wires. NOw if you want a device to remember its settings they you have your memory/12v power wire which keeps power constant to the device so it doesnt loos the settings. However after reviewing your pics and assuming that gauge looking piece is a dial that you can turn right for more boost and left for more that is the one that runs to the ecu(if thats where its suppose to go) as you can see that dial has three wires that run to the soleniod so that dial acts as the Controler I was talking about before as you can see there is a black ground already running to it along with the red and white wires which create a circuit for you. Now the easiest way to make this work is to find out if your "mate" still has his car. As you dotn need the engine to find out where it plugs into you just need to find the wire(meaning look near the ecu at the harness and see where a wire was cut/w a yellow wire hanging off. It should be either on the main harness or the it could be in the engine bay on the passangers side on top of the fender where you would plug an fcd into. Those would be my only guesses that if the ecu were somehow able to control the boost then it would have to monitor boost through its main harness reading or that sensor. Can yoru friend look at his car for you???????(I still just dont see how the boost could be controlled at the ecu. The problem is that the wastegate is mechanical on FCs and has no electronic control. I still think there is something missing . Can you get a pic of that other side of the grey box that is not pictured for me)

grinder

thanks matey

the car has gone to the "big garage in the sky" now - so thats not an option

the other side of the grey box .. wait for it .. is grey - and flat and very boring

so to sum all this up

1 - the unit is a grey box with a dial on the end of the wires
2 - it turns from left to right ( and stops at either end )
3 - i ASSUME that its a some sort of variable resisitor thingy ( ie 0.0v at one end 12.0v at the other - or something like that )
4 - we dont have the car to see where the wiring went
5 - a UK tuner ( very specialised ) says that the yellow wire goes to the duty selaniod ( see one of my posts )
6 - i dont think the unit remembers its settings ( apart from the dial not moving )
7 - i have read the sevice manual thingy and yes there is a boost duty selanoid on the car - but it doesnt tell you what wires come out of it - but it does have some sort of voltage coming out of it
8 - to be honest - i dont think it comes out of the ecu ( or into it )

and that about sums it all up from my end - if we cant figure this out - i will have to wait a few months to get the car road legal and then take it to the tuner to see if he can point to the wire

Thanks for all your help - its just another job on the car now ( along with the 15,000 others )

Big thanks

"or the it could be in the engine bay on the passangers side on top of the fender where you would plug an fcd into. "

that sounds really wierd - thats on the drivers side on mine ( yeah i know - uk car - right hand drive !! lol )

bigturbo

Ok well there is no solenoid that has any wires coming off of the wastegate on the u.s. versions. I hit it before but your right this will not need any memory settings because the dial mechanically holds the setting you have it dialed it too. So then I can def tell you the yellow wire is the one left out so all you need to do is hook it to this duty soleniod you speak of. I would say search the FSM(factory service manual) for that wire on the car and you should be good to go. Do you have a boost gauge installed so you make sure you dont go too far??

grinder

thanks big turbo !

i have a boost gauge yes - so i can see whats happen !

i think i will let this thread die a death and go and see one of the UK tuners - so see if they can point me in the right direction

i looked in the FSM , i can find a boost selanoid - but no wiring diagram for it

oh well eh

thanks for all your help though
