1ZZ 2ZZ ECU Master BLACK Plug-n-Play Stand Alone ECU

**If you have a 2000-2005 MRS 1ZZ or 2000-2002 Celica 1ZZ/2ZZ MANUAL ONLY, check out the ECU Master Black, Direct Connect, all the same great tuning power, not at a lower price!

This is the parallel ECU version – works on manual and automatic cars. The stock ecu is used in parallel to control some basic functions like relays and of course automatic or SMT transmissions. As with all ecu master installs, this is for off-highway use and has no OBD functionality, not emissions legal.

  • 2000-05 MR2 Spyder (MR-S) – Manual and SMT transmission all
  • 2000-05 Celica GT (1ZZ) Manual and Automatic
  • 2000-02 Celica GTS (2ZZ) Manual and Automatic
  • 2003-05 Celica GTS (2ZZ) non-US models with cable throttle

Manufacturer’s Brochure

EMU Black features sophisticated strategies for drive-by-wire throttles, providing a wide range of control with advanced algorithm reliability (fault / error) and failsafe provisions. System capabilities will increase over time because of the ease of upgrading (free) firmware (eg. New strategies, trigger patterns, CAN-Bus data streams).
The EMU Black is one of the best values in engine management available anywhere. Built-in hardware includes a 4 bar MAP sensor (for reading manifold pressure up to 43 pounds of boost), built-in wideband controller (just add your choice of a Bosch 4.2 or a 4.9 sensor, no external controller needed), 6 built-in high current ignition drivers (can drive smart or passive coils, up to 12 smart coils for waste spark), 2 EGT inputs, CAN and Serial on board, on-board Drive By Wire control, and much more. All of these features in a beautiful CNC Aluminum enclosure that’s small enough to fit in your hand.
