New project: Flash Online - flash memory emulator (29F200 / 400 / 800)

Due to numerous requests, the development of a new project was started: a real-time memory emulator for ECUs with 16-bit flash memory, such as 28F200 / 400/800 and 29F200 / 400/800 (256-1024kB).

Assigned targets:

  • Live tuning!
  • Online software support - TunerPRO RT
  • Support for hardware table / map tracing (Address hit tracing)
  • Work with any software through CobraRTP Utility, (read / write firmware in .bin format)
  • The ability to upload and use 2 firmware (full) with subsequent switching in real time without the participation of a PC (dual mode Dual-mode)

What does it give and what is the difference from “firmware” via OBD connector (in boot mode)?

Indeed, most ECUs with this type of memory (except 28Fxxx) are easily "flashed" through the diagnostic connector (OBD), which does not require intervention in the hardware of the control unit. But, if you need not just load the finished firmware into the ECU, but adjust the ECU for an engine with a non-standard configuration? Obviously, this is very dreary and will take a lot of time, if only for the reason that downloading the calibrations, and even more so the entire firmware (full), usually takes a long time (5-15 minutes).

But with the help of a flash memory emulator, you can edit the firmware in real time without turning off the engine! Those. it looks like a built-in programmer in an ECU, or as some call it an "engineering block". You do not need to download the entire firmware every time or even the calibration area, but only those maps and parameters that you are editing at a given time, which takes a split second.
Thus, you can feel the result of changes made to the firmware (calibration) immediately after changing a specific tables (parameter)!

How is this device connected to the ECU?

Since the device is an emulator of a memory chip, it requires installation instead of a standard chip for operation. To connect, you need to dismantle the standard flash chip and mount a special adapter for the emulator. This is usually done using a thermo-air soldering station.
Next, you need to connect the emulator to the PC using the USB interface, download the full firmware, and then you can perform live tuning!

  1. Отлично. Давно ждал. Когда ориентировочно можно будет заказать, и цена вопроса?

    • Добрый день!
      Если испытание пройдет по плану, то начало релиза намечено на июнь этого года.
      Стартовая стоимость комплекта 255$.
