Do I have to reprogram my engine’s computer after installing COMP’s Cam Phaser Lock Kit?
Yes, you MUST have your engine’s computer reprogrammed for the engine to operate properly after
installing the cam phaser lock. The Chrysler factory computer does a diagnostic sweep test of the cam
phasers upon start-up. If the computer cannot get the cam phasers to reach their programmed
maximum limit, an error mode occurs. When reprogramming your computer; just make sure that the
maximum retard amount entered for any of the cam phaser tables in your tuning software is set to zero.
Installation Instructions
Step 1
There are two bolts where some of the threads have been partly turned down as pins. The tool slips
over one pin/bolt and is used to relieve the spring tension. The other one must remain in the phaser
during the lock installation. Place the tool over the visible pin. Run the adjusting screw down until it
just touches the outside face of the trigger wheel. Tighten the screw one turn. This takes the spring
pressure off the pin.
