Adaptronic Modular ECU eMod012 for S8 RX-7 FD3s

Adaptronic Modular ECU eMod012 for S8 RX-7 FD3s

This product is one of Adaptonic’s plug-in ECUs. Also called RX7 S8 or FD Twin Turbo JDM.

Please note that this ECU will work with Some S7 FD’s depending on the ECU connector style, if your not sure please send us a picture so we can help identify your specific requirements.

Our 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, we came up with a system which would give people greater flexibility and at the same time, overcome the limitations of our main product line, the Select ECUs.


  • 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)
  • Wireless communication
  • Maximum output of 22 (8 ignition, 8 injector, 4 auxiliary, tacho and fuel pump)
  • 3 complementary drivers in the ECU to drive inverse outputs
  • Smooth transition to direct fire
  • Drive dual speed fuel pump
  • Injector staging is automated
  • Has an option to manually set the percentage of fuel to be delivered in secondary (or third, or fourth…) stages
  • Handle the factory pickup, the 36-1 FFE trigger with the factory sensor, and the 36-1 FFE trigger with a Hall effect sensor
  • Great twin turbo control
  • Dual speed thermofan
  • Fast USB communication, requiring no drivers
  • Headphone port for listening to the knock sensor while tuning
  • 4 x serial in ports
  • 1 x CAN port
  • Power over USB to do loading of maps, firmware etc without having to provide it with 12V power
  • 32MB of onboard logging to flash
  • Exception logging, able to detect faults and log a bunch of things that happen around the same time to help with ECU setup and tech support
  • Tested to MIL-STD-202G, a military vibration standard, which varies the frequency and peaks at 7.5g of oscillating acceleration

eM0d012 ECU plugs directly into the factory loom, with additional inputs and outputs available on unused pins in the factory connector. The additional pins you have access to give you the following options:

      • An additional 2 injector outputs
      • An additional O2 input, and 2 additional 0-5V inputs for logging or other functions like sequential box strain gauges
      • Additional ignition output for conversion to direct fire
      • Oil pressure, fuel pressure and oil temperature inputs (plus we read the fuel temperature input and use that in the fuel density calculation)
      • CAN (Wideband lambda can be connected via analogue input, or via serial.)


The base eMod012 ECU can also be expanded or upgraded to use one of the following boards:

      • DBW / e-throttle controller
      • Mini Output Board (6 x push-pull aux)
      • Mini Analogue Input Board (4 x analogue inputs)
      • Mini Real-Time Input (6 x inputs) – additional 2 x CAS, 3 x VSS, 1 x flex
      • Lambda Controller
      • EGT Inputs
