M1200 Adaptronic ECU - Up to 4 Cylinders / 2 Rotor Max / NA6-NA8 Plug-in Miata / Looms, connectors sold separately

*Includes 10% GST


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

This product is one of the three wire-in universal ECUs we have for our line of Modular ECUs, and is considered to be the most basic. It replaces the e420d Select ECU for a wire-in 4-cylinder / 2-rotor engine application using the technology from our new Modular ECUs. It is worth taking note however that the M1200 can not be expanded or upgraded with more inputs or outputs. The injector drivers are also only meant to support applications with high impedance injectors.

The M1200 can also be used as a plug-in ECU for the NA6 and NA8 Mazda MX5/Miatas with 2-plug ECUs. Otherwise, connectors and looms for a wire-in application are sold separately.


What's in the box?

  • USB (tuning) cable
  • 1GB USB Stick
  • Adaptronic Stickers


General Features


  • Replaced the e420d for 4-cyl /2-rotor  engines using the technology from new Modular ECUs
  • 48 pin Mate n Lock
  • Fast USB communication, requiring no drivers
  • Headphone port for listening to the knock sensor while tuning
  • 4 x serial ports
