eMOD013 Adaptronic Modular Plug-in ECU for Mazda RX8 S1 (Standalone)

*Includes 10% GST

A direct, standalone Plug'n'Play ECU for the Series 1 Mazda RX8.

Adaptronic Modular ECUs offer more control and greater flexibility for the tuners while maintaining their excellent value-for-money.

Please take note that the second version of the ECU will support the following:

  • Cruise control
  • Traction control (DSC)

Cruise and traction control will later be supported through a firmware update on the first version units.


Factory O2 sensors are not supported.


For additional information on how to install features on the S1 Mazda RX8 please refer to the: ADAPTRONIC S1 MAZDA RX8 HOW TO PAGE

What's in the box?


    • Engine control unit
    • USB (tuning) cable
    • 1GB USB Stick
    • Adaptronic stickers


General Features


  • Modular system, so that people can buy hardware upgrades later as their needs develop (eg additional inputs, outputs, or specific functions, eg drive by wire or built-in lambda)
  • Built-in Oscilloscope; to aid in external hardware & wiring faults etc
  • Built in Simulator to test ecu logic & input/outputs without engine running
  • Maximum output of 22 (8 ignition, 8 injector, 4 auxiliary, tacho and fuel pump)
  • Full Sequential Fuel & Ignition Control- Direct fire capable( 4 individual coils on a 2 rotor, up to 8 total-will run a 20B, 4 Rotor, 4/6/8 cylinder properly), and Individual Rotor/Cylinder Injector Trim( individual control up to 8 injectors)
  • 3 axis accelerometer (G sensor) and rate gyro
  • OMP, OEM DBW Throttle Body & Stock Fan Control
  • Fast USB communication, requiring no drivers
  • Headphone port for listening to the knock sensor while tuning
  • 32MB of onboard logging to flash
  • Tested to MIL-STD-202G, a military vibration standard, which varies the frequency and peaks at 7.5g of oscillating acceleration
