    This is a standalone ECU for the 93-97 Toyota Supra Turbo applications listed below. This ecu completely replaces the factory ecu and controls every aspect of the engine. We use it on almost every project we do because it performs excellently at a reasonable price. 

    The series 2 EMS has some new features over the Series 1 box. It’s a all new platform that is no longer tied to the GEMs hardware. The new unit has 12 peak and hold injectors so a resistor box is no longer needed. It runs in direct fire so wasted spark is no longer used and a smoother, factory quality idle can be had. It uses either a serial port or usb so hunting around for older laptops will be a thing of the past. The internal logging has an increased capacity. With the series two you can password protect your maps so if your tuning and don’t want your work looked by others you have that option. It will work with the existing gauges so your AEM wideband or serial gauge will be a direct transition.
