Has Anyone Received A Call Back From Fast?

[Larry Hill]

When I get back to the shop I’ll post Robin’s recommendations. I think they’re Hemi specific for the injector harness and coils packs.

554-113 HP ECU
558-308 Main Power Harness
558-116 Main Harness
554-122 Coil Drivers
554-100 NTK 02 Sensor

Hope this helps

Hey Larry,
If you don't want to have to get the laptop out every time you change the 2 step settings I sell these. You might not be using a two step, but if you are,and your new harness has a power tap (it probably does) it will plug right into it. Or for the guys running a Dominator it plugs right into the J4 port of the ECU. Robin or I will have to add an advance table to your tune to make it operational, but they work just like the MSD ones. I had an engineer up in Detroit make them up for me. Whatever your "Base" setting in your Rev limits are, this will allow you to add up to 1100 RPM of adjustments. Pm me if your interested.
