What’s up fellas! I just noticed my launch control is always active without pressing the clutch. I check the switch and it’s working fine. I haven’t check the harness side yet but I’ll do that next. Anyone have this issue before?

Thanks
Tony
 
Mine was intermittently turning on so I just disabled it. I wish I could tell you why, but I've seen many people with this problem.
 
Bad ground? (Possible)
Or use the Arc2 box for that :p ???

What’s arc2 box? I’m pretty sure this happened after I switch to non cruise cable. I don’t have the old cable. Is this the connector for the cruise?

Trigger it from wheel speed instead say under 2 mph.

Link only has "Disable launch at or above Xmph". I can't free rev past the launch limit. I'd like it to work only when pressing the clutch, how it used to.

Pretty sure link sees that the clutch switch is always grounded. Think I need to figure out how to bypass the cruise module.

the dynatek arc2 ignition box. the kit makes it a pretty much plug-n-play for our cars. its and ignition cut style 2step which imo is better than a fuel cut.
 
is your vehicle speed sensor operable? If the launch control is disabled after 4 mph and ecu does not see 4 mph it will always think the car is less than 4 and enable launch control. I found this out by forgetting to plug the speed sensor in years ago LOL.

Yes. Speedo is working and link sees it.
 
I want some too.......
