Abstract
An electronic data link that services components of the vehicle including components other than the engine and an electronic engine management system that services the engine operate in different data formats and are interfaced by a special electronic module that provides translation services for accomplishing bi-directional through-transmission of data between them. The module has programmable memory with different levels of security and can detect the absence of a vehicle speed sensor at incipient vehicle launch. The speed sensor serves both the data link and the electronic engine management system through the special module.
