My Asc off light just came on. what are the reasons for this because the manual just says to go straight to mitsubishi. Thing is i dont really have a mitsu nearby. Can you give me any advice on this.. thank you.

 

What were you doing? A little more information would be helpful.

 

I wasnt doing anything different. i had just put my intake and upper intercooler piping about 2 weeks prior. but what i noticed was when i am at a complete stop, i take my foot of the brake and it doesnt go all untell i press the gas. you know it should go in idle speed, but it doesn't. its a MR so its an automatic.

 

If I'm not wrong, this can happen when airflow or boost exceed limits, for example after a performance tune or if the MAF sensor does not read properly the airflow. On MR, this can also lead to bad gearshifting and in general bad behaviour of the A/T.
Have you already tried to remove your intake (by the way, which intake is it?) and replace the stoke one? Intakes usually lead to incorrect MAF readings.

 

funny!!!

If I were you I'd replace the factory components and take it straight to Mitsubishi...use that warranty!!!

 

The only time I ever see that screen is when I hold the "ASC" button in for 5 sec or more, than I go out and play.
Just pressing it once to "off" does not fully shut it off,even though you may think it does. . try it.

 

Does it go on every time you stomp on your gas pedal? I had a BOV and that what cause my that light to come on. I brought my car into SCM and they couldn't find any problem, but they told me to switch back the stock bov and see what happen. They said it might be the air pressure. Ever since then the light never turn on.

 

Yea my car does that now if I try to use the 2-step. I never actually launch it but I just rev it up and It does that to me. I have the Cobb AP and I just clear the codes and the light never comes back on. It prolly is just the ECU saw too much boost or air. Maybe disconnect the battery and press the brake pedal a couple times and wait. See if it clears it.

 

have you tried resetting the ecu by removing the battery terminal?
