Nexus R3 carries the Nexus integrated ECU/PDM/logging/wideband concept in a smaller package. It is the cleaner fit when the build needs modern vehicle control but not the full Nexus R5 channel count.

Best fit
- You want a compact, premium build with ECU, PDM, CAN, logging, and wideband all integrated in one unit.
- Tidy wiring and control integration matter more to you than chasing the maximum I/O count.
Choose this instead
- Choose Nexus R5 instead if you need more I/O, dual wideband support, or three CAN networks.
- Choose Elite 1500 or Elite 2500 instead if you don't need integrated power distribution.
- Choose a universal wire-in harness if your build shouldn't depend on factory-harness replacement.
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.
