TEC3 Engine Management System by Electromotive

The new TEC│ represents the current in state-of-the-art fuel injection and direct ignition control integrated into one revolutionary package. The TEC│ is a PC-programmable engine control system featuring a powerful Windows-based tuning environment. Converting from carburetion to fuel injection has never been easier than with the TEC│. Whether you choose to run throttle body injection, multi-port, or individual throttle bodies,the TEC│ will provide you with the ability to tune your engine to its peak capabilities.

Street enthusiasts will enjoy the benefits of a ‘distributorless’ ignition system that not only is infinitely adjustable, accurate, and powerful, but also gives you improved firewall clearance and freedom from all those ignition amplification boxes that you used to run in the past. If you are running an aggressive profile camshaft, idle control has always proven to be problematic for lesser engine management systems, but not for the TEC│. Within the WinTEC software resides our exclusive ‘TPS/MAP Idle Blend’ table. With a few clicks of the keyboard, you will enjoy an idle quality that other engine management systems only dream of having.

For competition and ultra high output engines, the sophistication and power of the TEC│ system simply out-performs other production and aftermarket systems. With full control of the engine over all possible operating conditions, outputs that will control nitrous, boost, VTEC, and other devices, new rev-limiters with ‘Triple Smooth’ technology, and On-Board Data Acquisition, the TEC│ gives you Total Engine Control...and makes the competition green with envy!

The TEC│ Engine Control Unit

The new TEC│ ECU incorporates the winning features of our previous TEC-2 system while adding an abundance of new features and a powerful new processing platform. Electronic Fuel Injection (EFI) control and patented digital Direct Ignition control is standard hardware for every TEC3. The anodized, laser-etched ECU with waterproof OEM style connectors and harness may be mounted under the hood or in the passenger compartment and will activate separate multi-coil DFU’s (Direct Fire Units) mounted adjacent to (or on) the engine.

Standard features built in to the TEC│:
  • PC programmable and configurable for 1, 2, 3, 4, 6, 8, cyl. engines and Rotories with a 12 cyl.and 6 cyl dual plug option
  • Operate in Open or Closed loop
  • Run True Sequential, Phased Sequential or Simultaneous Injection with individual cylinder trim
  • Configurable for TBI, MPI, TPI and individual throttle bodies
  • Additional Injector Output Drivers built-in.. Run Low or High impedance injectors
  • Full 150 mJ of Spark Energy directly to the plugs without misfire
  • New Dual Rev Limiters with ‘Triple Smooth Technology’.. 1st step retards timing to a negative -12║ degrees.. 2nd step cuts coil current in half.. 3rd step coil current and fuel are cut-off.. all three steps occurring within milliseconds!
  • Waste Gate (Boost Control), Nitrous Control with up to 4 stage retard available
  • Four Programmable GPO’s (General Purpose Outputs) to control or activate VTEC, Shift Lights, Water Pumps and Fans, A/C Compressor, Torque Converter and more.
  • New Programmable Adjustable Electronic Tachometer Output
  • Uses primarily GM type sensors
  • Diagnostic monitoring with codes issued through Check Engine Light
  • Easy to install bolt-on Trigger Wheel and Mag Sensor Kits available for many applications
  • Made in the USA
New On-Board Data Acquistion 
  • Adjustable Sample Rates up to 100 samples per second Simultaneously record data from up to 25 inputs including: Air/fuel Ratios, Injector Duty Cycle and Pulse Width, RPM and Throttle Position, Gear Position, MPH, Boost (manifold pressure) and much more!
  • Additional configurable Digital and Analog Input Channels View Multiple Data Graphs side by side or Graphs may be overlayed for comparison Graphic Screen Displays may be Printed.
  • Data may also be exported to a Spreadsheet program for further analysis Data Logging can be started and stopped manually using a switch, or the system can be configured to automatically start and stop via values pre-set by the user
In addition to rotaries, the TEC│ Engine Management System will run the following configurations:
  • 4 Cylinder
  • 6 Cylinder
  • 8 Cylinder
  • 4 Cylinder, Dual Plug
  • Staged Injection
  • Sequential Injection
  • TEC│ controler
