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.
