hello I believe that PIN 43 is used for the clutch position sensor. I own a 3rd generation eclipse and run dual ecu's, one of which is a flashable evo8 ecu. Since I am automatic I am trying to simulate a clutch position sensor so I can use launch control with my high stall converter. the problem I have ran into is that I tried grounding that pin to see maybe if I could toggle a ground into it to activate my launch control and I received no success. Does anyone know what that reads? is it just a 12v power that is removed when clutch is activated or is 12v pushed into it when clutch is pressed. I was just scared to fry my ecu.

 

im wondering the samething as you.....i been searching here for hours and i figured out that in order for the launch control to work it needs the signal from the vehicle speed sensor!!!!.....so can we do this??

 

I am working on it. tomorrow Im going to use my friends car to see if I can check the harness for power or not. I want 2 step soo badd

 

me too0o!!!! ...two step on auto with the evo ecu!!! ..........please let me know if you get it doned....post it on the dual ecu thread on club3g...im

I know you are im 04gsNA

 

Pin 43 is right

 

and far as how the pin works? u got me cause i was doing something simular. i wasnt getting a reading 12 or ground clutch in or out on that pin.

the clucth saftey switch is wierd too....its a constant ground pedal out....it kills the ground to one side when pressed in. Its usually the other way around.

 

so the ground idea is right, when the clutch is pressed the PIN is then grounded?

 

like i said i had a test light on the pin and had someone pressing the clutch in and out with ignition on and i got nothing. i tried my tester grounded and hot.

you using rush?

 

i tried and ground the clutch pin and it didnt do noting,the stationary limiter was still on even if the clutch pin is connected or disconnected.....

 

oh ur using the stock stationary rev....i believe its speed sensor relalated. i know when my tires move at all it comes out of stationary rev..

 

whats rush?

 

yea the stock one and your right i been reading in the forum and people mentioned the speed sensor...how could i trigguer the two step to turn it on and off then??

 

o maybe then since its speed sensor,we just have to put the value in and the when the car is running the stationary limiter should disable itself!!

 

this is something I will try tomorrow
