AMP EFI MS3Pro - FD Mode; Rotor; RX8 Mode

7.3 Ignition Settings 7 ADDITIONAL ITEMS: BEYOND BASIC FUEL AND IGNITION CONTROL
7.3.11.2 FD mode The third generation RX-7 retains a wasted spark coil for the leading plugs, but the trailing
plugs are individual logic level coils. As with FC mode, “number of coils” needs to be set to “wasted spark.”
Ignition wiring:
• Spark A Leading coil (IGt-L)
• Spark C Front trailing coil
• Spark D Rear trailing coil
Note that FD mode does not use spark B - this is done to match the RX8 mode. If you ever convert to coil on plug,
this means you only have to change one wire instead of three.
Fuel wiring:
• Inj A Front rotor primary injector
• Inj B Rear rotor primary injector
• Inj C Front rotor secondary injector
• Inj D Rear rotor secondary injector
7.3.11.3 RX8 mode The RX8 mode is automatically enabled if you set the number of coils to “coil on plug” and
the number of rotors to 2.
Ignition wiring:
• Spark A Front Leading coil
• Spark B Rear Leading coil
• Spark C Front trailing coil
• Spark D Rear trailing coil
Fuel wiring:
• Inj A Front rotor primary injector
• Inj B Rear rotor primary injector
• Inj C Front rotor secondary injector
• Inj D Rear rotor secondary injector
7.3.11.4 3 rotor Using three rotors requires coil on plug ignition to be set.
Ignition wiring:
• Spark A Leading coil A
• Spark B Leading coil B
• Spark C Leading coil C
• Spark D Trailing coil A
• Spark E Trailing coil B
• Spark F Trailing coil C
Fuel wiring:
• Inj A Primary injector A
• Inj B Primary injector B
• Inj C Primary injector C
