Best fit

  • You're building a high-end race, advanced street, or competition car that needs ECU plus PDM-level control.
  • You need maximum injector, ignition, auxiliary output, CAN, logging, and validation headroom.

Choose this instead

  • Choose Nexus R3 instead if you want Nexus integration in a smaller package with less I/O.
  • Choose Elite 2500 instead if you need an advanced universal ECU but not the integrated PDM, wideband, and logging system.
  • Choose a universal wire-in harness if factory-harness replacement isn't your priority.

Application notes

  • Not sure this is the right part? Send us your vehicle, engine package, wiring approach, sensor set, and CAN layout and we'll help you choose.
  • Intended for sanctioned off-road and competition vehicles that aren't emissions-controlled. You and your installer are responsible for compliance with applicable laws and regulations.
