I can't get my launch control to engage for the life of me. It should be in my performance map #1 I believe... vdc off, clutch in, WOT...am I stupid or am I missing something...unless it's hidden on another map that I never use/don't have tuned... any ideas or similar issues? 2005 6mt coupe, osirus uprev and ARC platform.

 

ARC isn't assigned to a map, it's just there. Do other ARC features work?

Is the car warmed up and no check engine lights?

Make sure you're in gear also. Took me a few tries the first time, basically need to just mash the gas pedal.

Also kinda rare, but it might need to be reflashed. I've been playing with my tune lately and once or twice now ARC features didn't work. It was probably user error on my part, but flashing the rom file again seemed to fix it.

 

I actaully have upstream o2 sensor codes at the moment so maybe that is the problem, I do have the ARC platform so it's good to know that it's not assigned to a specific map. I can check that off the list, I'll clear those codes and play with it, I really appreciate the help that seems like a good place to start. I'm gonna see my tuner in about a month to make sure thone sensor errors aren't representing a bad trend in my A/F. Realistically I should probably take it easy on the WOT until I know my A/F is stable through all of the RPM band anyway. Thanks again.

 

It's not working because of the check engine codes. I recently has a camshaft sensor go bad and noticed no lift shifting wasn't working. Upstream O2 is the important ones, if you have a lot of miles, they're probably just old and due for replacements.
