- Use with 121-6011
Features: - Splice-free Installation of the MSD 6-Mod Controller to factory equipped EFI vehicles
- All connectors plug directly to the factory units.
- Tach adapters ensure that the ECU and the 6-Mod receive the correct signals for proper operation
- The 6-Mod allows users to advance or retard the factory's timing curve, program a step retard for use with nitrous systems or even map out a timing curve through a laptop by using MSD's Pro-Data+ software.
For Street Rods & Retro Muscle Cars
This Ignition Controller will fire the coils and control the timing when you retrofit a Ford 4.6L or 5.4L (SOHC/DOHC) with a carbureted intake manifold. The Controller plugs into the coil packs and engine sensors for a direct installation. A 6-Mod can be connected to factory EFI 4.6L or 5.4L (SOHC/DOHC) to give the advantage of ignition control. Using Pro-Data+ software on a PC, you can program custom timing curves, a step retard, two step and a vacuum advance.
