EMOD013 / Adaptronic Modular Plug-In ECU - S1 Mazda RX8 (standalone)

This product is one of Adaptonic’s plug-in ECU and is a direct standalone plug and play ECU for the Series 1 Mazda RX8.

The main objective in creating the Adaptronic Modular ECU line is to work towards Adaptronic’s mission which is to give people control. In doing this, they came up with a system which would give people greater flexibility and at the same time, overcome the limitations of their main product line, the Select ECUs.

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.

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
Wireless communication
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
