Adaptronic Modular ECUs

Ya en 2011, Adaptronic comenzó a diseñar su ECU de próxima generación. El objetivo principal era trabajar hacia su misión, que es darle control a la gente. Al hacer esto, Adaptronic ideó un sistema que daría a las personas una mayor flexibilidad y, al mismo tiempo, superaría las limitaciones de nuestra línea principal de productos, la linea de ECU’s Select

The original goals for the new model were:

  • Modular system, so that people can buy hardware upgrades later as their needs develop (eg additional inputs, outputs, or specific functions that we won’t force everyone to buy, eg drive by wire or built-in lambda)
  • Offer a waterproof option, probably using Superseal connectors
  • Retain the design flexibility to build plug-in ECUs easily
  • Complete new units from the ground up, including new software( Eugene)

And in addition, several “processing” ideals:

  • “Wifi” Wireless communication
  • Faster USB communication, requiring no drivers
  • 4x serial in ports
  • Up to 2x CAN port
  • 32MB of on-board logging to flash
  • Exception logging, so being able to detect faults and log a bunch of things that happen around the same time to help with ECU setup and tech support( separate from main integrated logging)
  • Bigger maps( 32 x 32), more of them, and more dedicated maps.
  • Built in Oscilloscope; to aid in external hardware & wiring faults etc
  • User definable gauge displays & maps with warning presets
  • Up to 24 ignition & 24 injection drivers
  • Up to 86 total outputs
  • 4 VVTI channels 
  • 4 Electronic throttle body channels
  • Multilingual
  • Advanced trigger fault detection with variable filtering etc
  • Arbitrary Logic Function( easier version of the advanced mode in the current E1280s– the ability to implement any software logic you want- in development).
  • Retain the ability to power the ECU over USB to do loading of maps, firmware etc without having to provide it with 12V power
  • Retain the headphone port as on  current Adaptronic models
  • EUGENE tarp 200dpi (433x1024)

And on the engine interface side of things:

  • More inputs standard; consistent with our value of “encouraging the right way”, we should have fuel pressure, exhaust back pressure etc as standard inputs
  • 2nd built in 4 bar map sensor for dedicated EMAP( exhaust manifold back pressure)
  • More outputs standard; again we should be encouraging people to run 6+ cylinder engines fully sequentially with direct fire
  • Increased processor speeds
  • Greater built in protection against end user voltage spikes, wiring faults, EMI, etc
  • PNP models will have in house tested lag settings for Modular injector drivers
  • 3 axis accelerometer (G sensor) and rate gyro

So with this in mind, we present the new Modular ECUs; M2000 & M6000

M2000 – space for 1 large module (8 injector, 8 ignition, 4 aux) + 1 small module (for user expansion)
M6000 – space for 3 large module (8 injector, 8 ignition, 4 aux, plus 2 x user expansion) + 4 small modules (for user expansion)

All of the ECUs have:

  • 1 Control module
    • 16 analogue inputs, including a knock input
    • 2 x built-in 4-bar MAP sensors( 1 for intake pressure & 1 for exhaust pressure )
    • ECCS / fuel pump and tacho outputs, but no other outputs
    • 3 axis accelerometer (G sensor) and rate gyro
  • Space for 1 or more large modules, of which one will be an output module:
    • 8 peak and hold, switching mode injector outputs (unused injector outputs can be PWM low side drive outputs)
    • 8 current limited ignition outputs (unused ignition outputs can be PWM low side drive outputs)
    • 4 current limited push-pull outputs (can be PWM)
    • ANALOG: EGT and 0-5V inputs (number of each not finalized yet – in development)
  • Space for 1 or more small modules, which can be
    • Additional 6 push-pull PWM outputs
    • Single channel Drive by wire controller ( in development)
    • Lambda controller ( in development)
    • Additional real-time inputs (for additional VVT channels, multiple vehicle speed inputs, flex fuel etc)
    • SMALLRT: 2 x additional cam sensor inputs, 1 x dedicated flex input, 3 x additional wheel speed inputs ( in development)
  • PNP( plug and play models) – all contain one large module, others as required depending on the application, and additional spaces for modules depending on the number of spare pins on the factory connector
