Considering 2014 Hemi (5.7) 1971 Demon

Chaditotx,

It is my BELIEF, that the MSD controller will only work on the 03-08 5.7 motors, and will not work on your VVT motor.

As of right now there also APPEARS to be no aftermarket control of VVT from a standalone controller. As a result I'd strongly recommend a stock computer and a wiring harness from Hot-Wire. Megasquirt has a VVT controller but I don't think anyone has gotten it to work with the Hemi, YET.

What intake are you running?

One option is to get a VVT lockout kit from Comp Cams, remove the MDS lifters and actuators from the motor, and then get the appropriate plugs for your motor. Unfortunately this may still NOT work as Chrysler changed the tone ring on the crank in 2009, and I am UNSURE if the MSD Hemi 6 controller can read the 09 and later tone rings.

Hope this helps,

Regards,

Joe Dokes
