The PE3-8400A is a compact, standalone engine control unit in a lightweight aluminum enclosure, designed for performance and custom engine builds. It provides fully programmable fuel and ignition control so you can tune your engine for power, response and reliability.
- Standalone programmable ECU
- Aluminum enclosure for light weight & easy mounting
- Programmable fuel & ignition maps
- PC-based tuning software
Built for serious custom and motorsport builds
The PE3-8400A is a flexible platform for four-stroke and two-stroke engines when matched with the correct sensors, wiring and tune. It is well-suited to road race cars, time-attack builds, drift cars, off-road rigs, engine-swapped street cars and R&D test engines where you need complete control over fuel and spark.
Key capabilities
Fuel & ignition control
- Fully programmable fuel and ignition tables using PC-based tuning software.
- Supports a wide variety of engine configurations when wired and configured correctly.
- Per-table and per-parameter adjustability for cold start, warm-up, load, throttle and more.
- Can be configured for performance or economy depending on the calibration.
Inputs, outputs & flexibility
- Multiple analog and digital inputs for typical engine sensors (MAP, TPS, temperature, etc.).
- Configurable outputs that can be assigned to injectors, coils and auxiliary functions where supported.
- Capable of interfacing with a wide range of commonly used sensors when properly calibrated.
- Compact aluminum case makes it easy to mount in tight engine bays or cabins.
Tuning & motorsport features
