Our favorite standalone ECU for the 3SGTE!

The ECUMaster EMU Classic and Black ECUs alike are packed with features that make optimizing your stock or highly modified engine in your MR2 easy, safe, and affordable!

Classic vs Black - The Black offers more modern features such as DBW capability and CANbus. The Classic can run out of I/O quickly and is not receiving many software updates at this point. The Classic has run many MR2s beyond 700whp, but the Black is certainly worth the upgrade for anyone who wants to future proof.

We at ATS Racing have tuned more 3S engines than anybody.

With this purchase we include a comprehensive start up map, as well as email support to help you get all set up and ready for tuning.

Tuning is always required with a standalone ECU, but a good base map makes everything easier. You may bring us the car for tuning, take the car to your own tuner, or we can tune it remotely!

• Plug and play Bosch 4.2 wideband O2 sensor
