EMtron KV8 Wire-In ECU

Stop compromising on your engine management. The EMtron KV8 is designed for high-level motorsport applications where data speed and processing power are non-negotiable. Whether you are building a 1000+ HP drag car or a time-attack weapon, the KV8 provides the granular control needed to manage complex fuel, ignition, and torque strategies safely.

Unlike entry-level ECUs, the KV8 is housed in a billet aluminum 6061 enclosure, built to withstand the heat and vibration of a race environment. It features an integrated 4-channel oscilloscope, allowing your tuner to diagnose cam and crank sensor issues instantly without external tools.

Technical Capabilities:

• Engine Suitability: Perfect for V8 engines or sophisticated 4/6 cylinder setups requiring extra I/O.
• Dual Drive-By-Wire: Fully controls two electronic throttle bodies for complex intake setups.
• Advanced Knock Control: Industry-leading signal processing to protect your engine under high boost.
• Massive Data Logging: 32MB of onboard logging ensures you capture every millisecond of a pass.

We recommend the KV8 for builds where you need total flexibility. Because this is a wire-in unit, it allows for a completely custom harness construction, ideal for engine swaps or chassis where the factory wiring is being removed.
