ATS PNP ECU from ECUMaster

ATS Racing is Proud to bring you the ECUMASTER EMU!   Supplied with an ATS Racing Start-up Map FREE!! If you bought your EMU from another dealer Click Here

ECUMASTER EMU is an advanced engine management system. It controls all aspects of the engine, and provides emergency procedures in case of sensor failure. Using the latest technology in the field of electronics and software, the device has a very high potential and attractive price. It is capable of running anything from stock to full aftermarket 3SGTE using the available PNP adapter developed for ATS Racing. In addition to the options below, The EMU is capable of map switching, or true Flex-fuel operation, with dual cold start WUE, ASE, VE, Timing, and Boost tables for perfect operation no matter what Ethanol content. It has a built-in Wideband controller, VVTi control (Turbo Beams anyone?), Drive By Wire Throttle, Launch Control, Flat Shift, Antilag etc...

ECUMASTER ANDROID DASH available in Google Play!

ECUMASTER DASHBOARD connects to ECUMASTER EMU engine management system via BT module, showing real time data of critical engine parameters. All data also could be stored to log file for further analysis.
Please check for more information. 


ATS has already developed and tested base maps for Gen2, Gen3, and Gen4 3SGTE engines. Remote tuning available if you purchase the optional Wideband kit. PNP is available for Gen2, Gen3, and Gen4/Beams. The Gen4 PNP with some minor changes will operate the 1zz-fe and 2zz-fe. If you are swapping in a Gen5, have Doug at Wiregap build your harness with Gen4 ECU connectors.
