One of the newer entry level standalone EMS systems for Toyota Supra 2JZGTE. This is an excellent lower priced option built in Europe and gaining quite a bit of publicity and use in the drifting scene, because of it's robust platform and aggressive pricing.

If you're comfortable learning to tune or have access to a solid tuning shop and are on a budget this is a good option for Supra owners.

The ECU MASTER 2JZGTE Plug and Play is a complete plug-in standalone ECU for the 1993-1998 Toyota Supra with manual transmission.

This plug and play ECU will also operate an Aristo 2JZGTE engine so long as it is used with a manual transmission. Vehicles with USDM 2JZ engines will need to purchase an intake temperature sensor kit, as the MAF sensor is eliminated with the EMU. JDM 2JZGTE engines will make use of their existing IAT sensor. The Engine Management Unit controls all aspects of the engine, and offers failsafe strategies in case of sensor failures or other events. The EMU features more built-in value than anything else on the market, not requiring any external modules to drive up to 6 passive coils directly (up to 12 smart coils), a Bosch LSU 4.2 O2 sensor, 2 EGT probes, a Flex Fuel ethanol content sensor directly. The inclusion of a built-in 4 bar MAP sensor further adds to the value of the EMU.
