I put a stage 4 clutch in my acura with a h22a with a p28 chip yesterday and now the launch control wont let me go over 3000 rpms without jumping while driving. This is a new car to me so I dont know much about the history. What could cause this? Can I somehow disable the line lock aka launch control?

 

Did you plug in the VSS?

 

Non working speedo will make the ecu think your stopped and engage launch control.
