switch on the accelerator ?_?

[Hikari]

Few days ago I felt being a kid again so I sat in my car and pretended to race.

as I put my foot down the acclerator i heard a click and I took a look.

Hmm it seems that there is a switch on there that clicks when the accelerator is about half way down.

I've tracked the wirings and it goes to the inlet manifold and finishes at the ECU.

Went to work and had the guys at winger take a look and they weren't too sure either on what it could be.

Last resort was to try here.. anyone might wanna take a guess ?

fi5th injector?

Sneaky park light switch?

Some bugger shifted it from the steering column..

Trolololololo

[Hikari]

lol! pictures make things more interesting so here is what it looks like

[Joker]

what ECu

what CAR

[subieboy]

Looks like a reed switch?

Something to trigger a aftermarket boost controller or trigger maps maybe???

Like Joker said we need more info (more pics)

[Hikari]

ahh my bad!

Car is a 1996 rs legacy .

and if i remember correctly the ecu is factory

Car has no boost controller

[madmike]

thats aftermarket a....

Could have been for heaps of diff things.

Boost control

flat shift

launch control

throttle limit

Alarm

Like i say.. heaps of different things

[Hikari]

I was guessing a little that it could be a limit to throttle.

My rs is actually boosting rather very low than other rs's. was checked at work to make sure no vacc leaks etc.

0.5 primary 0.7-8 secondary

heres some more pics of the switch in different angles. Can't take pics of it going to the manifold as i would have to take a sh*t load off to get to it

[Joker]

soemthing to do with the exhaiust cutout?

[Hikari]

not that one.. my cars well over 90dB at idle...

NOS switch?

I wish!!

Maybe its like with a twin barrel carb, as it goes to the inlet, when you open up the throttle past a certain point it opens both of them, something like that, but there's only one air inlet, so not quite like that, probably a similar mechanism, only electrical. Only thing I could think of that would be accelerator controlled, well smart to be accellerator controlled.

It is not a "subaru" OEM part, has been added aftermarket in Japan( at a guess) could be many things,

disconnect and see what happens

Trace the wires and see where they go to?

[gazzy2000]

years ago on my SUbaru Leone i wired in a switch on the accelerator that cut the aircon out when the accelerator was pressed 3/4 down, in order to give more passing power etc for the 1800cc beast LOL, all in the name of not having to turn the aircon off manually to get maw power

Worked well & Bloody handy when passing cars etc, prolly gave another it another 15 HP lol

its unlikely but to test if your switch is not doing this "aircon cut out" > turn key on engine off > turn on air con > press accerator hard down > listen for loud click at aircon pump under bonet as its turned off and on when pressing accelerator (or try this again when engine running)

Inlet mani and ecu

It seems like the most logical thing that would be there.

but then again, logic doesn't always find itself into car mods.

[Hikari]

Have tried putting the a/c on and holding down the pedal. the clutch in the a/c did not click at any point.

I think i will take the car out tomorrow and see what happens if I disconnect the wires...

[mattapo]

ill take the switch off your hands

[Hikari]

hahaha would like to know what it does first

[Joker]

allright then : what pin on the ecu : my dollar is on speed sensor wire

[Hikari]

Hmmmm so I tried disconnecting the wires and it felt like that my primary turbo spools really late.

Usually with the switch it spools up around 2K rpm's but with the switch disconnected boost gauge started to go up at 3K's . Not too sure just my feeling.

Will have to clear a day on my calender and track to the ecu and see what it could be

thanks for all the replies!
