  • 8 EGT TYPE-K/N inputs (1200C/2200F) in separate harness
MaxxECU RACE outputs
  • 8 peak/hold injector outputs. 1-2 high or low impedance injectors per output. 8A per output
  • 8 ignition outputs. 5V signal to drive ignition modules, CDI units or coils
  • 9 extra LOW DRIVING outputs for additional features. Can be adjusted to control virtually anything like fuel pumps, idle valves. GPO 1-8,10 (2A), GPO 9 (5A)
  • 2 extra +12V DRIVING outputs (GPO 15,16) (2A)
  • 4 extra motor outputs (ex E-Throttle). GPO 11-14 (2A)
