True plug and play engine management

The UCON Flex is an advanced engine controller with self tuning capability that works in parallel with the stock ECU.  It can take full control of the engine management needs and while doing so feedback false signals to the stock ECU so it will think it is still running the engine.  This leaves all the OBD diagnostics in place and all the secondary systems work properly.

Includes Cam Gears, T-Stat and Adapter Plate

The included exhaust cam gears allow the cylinders to empty more completely on the exhaust stroke. The kit also includes a cooler, 170 degree thermostat and adapter plate which allows a more aggressive timing curve to be used and the incoming air is heated less by the engine so more power can be made.
