switch in my new car.. someone help

[Guest Boxhead]

ok, well i have this switch in my new car, sitting all alone, and its wired directly to the ecu,

i have had suggestions that it could be a boost controller. and also, some one else has said that it could be a idle changer, but it didnt do anythin either way for that to be it.. any thoughts??

im going for speed limiter removal

[Guest Boxhead]

ive been told on good authority that its a dual ecu switch, as in one for standard, and one for modified.. well, i can test that theory on a dyno i guess.

[PranK]

does it have an after market ECU?

[Guest Boxhead]

i dont know, it looks stock on outside, but the person i was talking to it about thinks it could be chipped inside.

[AndyMac]

I have heard of some Japanesse installing switches linked to the ECU as a remote "reset" switch. When pressed it resets the ECU, and/or puts it in diahnosic mode.

Thou, I think you'd hope for a performance switch then a reset switch.

I too have a unknown red button in my car.

It may also be an attempt at some sort of kill switch ???

I'm going with speed cut too.

Im going for the SELF_DESTRUCT swith. j/k

If its on stock R32 ECU its probably an EPROM switch. Switches over to different fuel and ignition maps and can also remove all the limiters i.e. speed, boost. Very easy to do.

wel thanks for all your help guys, because i like better shit, im gonna hope its what tom said

and sorry its not a destruct switch, and its not an eject switch

yeah three wires coming out.... im saying its an eprom switcher. you can switch the upper address pin on a larger eprom and select between two programs. make sure your ignition is off (and prob disconnect the battery terminal - i dont know if the program runs on this ECU when ignition is off but better safe than sorry) before flicking it!

you'd have to take the cover off and give us another pic where the wires come from. prob switches to another program to swap all the mappings over. just depends what those mappings are set to (higher octane?)

i cant get the cover off the ecu, tryed smallest screw driver, but its bloody tight...

Seeming its a GTS4.. would it have something to do with switching between 2wd and 4wd??

Belgarion and I had this idea last night.

[Guest Boxhead]

erin, its not a gts4, i wanted a gts4. but i ended up bidding on this gtst, and well yeh, its only a gtst

Girlie arms. Go do some push ups and then try it.

[Guest Boxhead]

nah, the more i try and turn, the more it slips.. it just wont budge...

[NismoGirl]

Ahh... I thought you still got one. Sorry

[darkhalf]

they have some type of automotive glue/laquer on the screws.

i tried different screw driver tips until one fitted 'nicely' to remove the covers from these types of ECUs. you have to push into the screw while putting pressure to turn it (to prevent rounding) and hopefully it should 'click' to losen it

[Guest Boxhead]

sweet thanks, ill go try it when the rain pisses off for 10mins
