The VORTEX X10 ECU is a sophisticated programmable Engine Control Unit
that combines the power of a Dual Core Processor to monitor sensors and adjusts Fuel flow, Spark timing and Voltage output to optimize engine performance under all operating conditions.

The X10 ECU replaces the standard ECU directly plugging into the standard wiring harness and is pre-programmed with (10 different) performance Fuel and Ignition Maps developed by Vortex Engineers using extensive dyno and field testing to adjust the engines power & torque characteristics for maximum performance.
