Engine Management System SECU-3

SECU-3 is a complex project, which includes a variety of tools and solutions for tuning of an internal combustion engine (ICE), starting from a simple microprocessor ignition system and ending with a full featured engine management system (EMS). Developments, presented on this site will be useful for motorists who want to upgrade or improve fuel feeding and ignition systems, as well as in cases when stock system was broken or for any other reasons when owner is not satisfied with its work. SECU-3 will allow to implement unique and innovative motor control features that often are not available in the serial control units. For many years (since 2006) of working on this project, the author developed a unique software and different versions of SECU-3 units, as well as auxiliary devices and fixtures.

For configuring of different versions of SECU-3 units, special software is used, called “SECU-3 Manager”. Connection to the unit is carried out by means of USB-cable or Bluetooth. SECU-3 Manager allows to fully configure all system settings for a certain engine, logging, to change firmware, to perform hardware diagnostics etc.
