Frequently Asked Questions

(click questions to expand answers)
  • How do I add an engine temp sending unit to my Gen-3 Hemi engine?
  • How can I tell if my salvage Hemi computer has security?
    • Check the ignition key from the donor vehicle, if the key is thick and gray then the computer has security. A thin black key means no security. You can also take the VIN number from the donor vehicle and contact your local Chrysler dealer.
  • How do I get a tachometer signal from my Hemi system?
    • Clip an MSD GMR Pickup (p/n: 8918) to one of the pink/yellow coil wires to get the signal. Set your tachometer to '2'. If your tachometer doesn't have this setting then you can use a Dakota Digital SGI-8 signal processor to multiply the signal x4.
