Miata MX-5 Adaptronic ECU


Miata MX-5 Adaptronic ECU

from 1,259.00


  • Built in MAP sensor to eliminate airflow meter
  • VE tuning to simplify injector upgrades
  • Easy to use software
  • Plugs into factory wiring
  • Compatible with many third party dashes and devices
  • Full closed loop operation
  • Flex fuel capable
  • Compatible with NA, turbo, supercharged and individual throttle applications
  • Boost control for turbo model (spare output available for turbo conversion with wiring modification)
  • Feedback for alternator regulator into idle control algorithm
  • Built-in alternator regulator control
  • Closed loop variable valve timing control (for VVT model)


  • This ECU also supports all the functions of the 440 ECU, however for advanced functions such as traction control, additional wiring and/or sensors will be necessary:
  • Flex fuel function – fill it up with gas/petrol or any ethanol concentration
  • Adaptive fuel control (self tuning) – reduces dyno time
  • Traction control function
  • 4 ignition and 4 injector outputs, fully sequential operation (requires a wiring change for direct fire ignition – factory ignition system is wasted spark)
  • 7 or 8 auxiliary outputs with more control functions than you can point a stick at (eg 2 x closed loop VVT, boost control, idle control)
  • Serial input for wideband O2 sensors (we recommend the MTXL)
  • Serial output for communication with dashes and dataloggers (we recommend the Race Technology units)
  • Inbuilt 4-bar MAP sensor
  • Headphone port for listening to the knock sensor while tuning
  • Basic closed loop ignition control
  • Closed loop fuel, idle, boost, 2 x variable valve timing control
  • Easy to use software
  • 8 programmable digital inputs
  • Dual maps
