FlashOnline - a tool for live tuning of the standard ECUs, which is a universal emulator of flash memory 28Fxxx / 29Fxxx.



  • Live tuning! Editing ot the MAPs/full ROM in real time mode.
  • Officially supported software - TunerPRO RT
  • Support for address hit tracing (tracing таблиц в TunerPRO RT)
  • Possibility of wireless tuning via Bluetooth interface (new) !
  • Compatible with any software such as WinOLS, RomRaider, etc. in teal time mode through CobraRTP Utility in live mode, (read / write firmware in .bin format)
  • The ability to download and use 2 firmware (full) with subsequent switching in real time without the participation of a PC (dual map - Dual-mode)*
  • Storing the firmware in a de-energized state - it can be installed permanently instead of the standard flash memory chip. *

Standart kit:

For full use, you need a mini-USB cable.

3D Models FlashOnline case (100kb)

Limitations when using FlashOnline:

- FlashOnline can indeed be installed and used instead of a memory chip on a permanent basis, but it should be borne in mind that the CR2032 battery installed on the device board serves to power the volatile memory when the device is turned off. Accordingly, the charge of this element is sufficient for 1.5-2 years.
- Dual-mod function only works in emulation mode 29f200 / 28f200, 29f400 / 28f400 (256-512kB), and is not supported for 29f800 (1024kB).
- FlashOnline does not calculate the checksum, you need to take care of that before loading data into the emulator.

This list presents some of the supported ECUs, the list is wider and limited only by the type of memory installed in the ECU.

As of February 2022 FlashOnline has been tested with the following ECUs:

Siemens MS41, MS42, MS43, MS5150, 5WK (SMG-2); 
Bosch ME7.1, ME7.1.1, ME7.5, EDC15C6, EDC15P+, EDC15VM

How do I know for sure if my ECU is supported?

To do this, you need to open the ECU and make sure that one of the supported ROM types is installed:

In this case, flash memory type 29F400 from AMD (AM29F400BB-70SE) in SOP-44 package


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 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 the engine with a non-standard Очевидно это весьма муторно и займет много времени, хотя бы по той причине, что загрузка  калибровок, а тем более прошивки целиком (full) занимает как правило длительное время  (5-15 минут).

Но с помощью этого устройства прошивку можно изменять в режиме реального времени, не глуша мотор! Т.е. это похоже на встроенный программатор в ЭБУ, или как некоторые привыкли называть «инженерный блок».  Вам не обязательно каждый раз загружать всю прошивку целиком или даже область калибровок, а лишь только те карты и параметры, которые вы редактируете в данный момент времени, что занимает доли секунды.
Thus, you can feel the result of changes made to the firmware (calibration) immediately after changing a specific tables (parameter)!

What is the advantage over installing a third-party (standalone) ECU?

The advantages of setting up a standard control unit, as opposed to installing an external one, are: preservation of the standard diagnostic system; no need to replace or recycle standard wiring; no need to replace or supplement sensors; there is no need to coordinate the on-board control units with the engine ECU (EWS-immobilizer, automatic transmission, dashboard, ABS, etc.).

Is WinOLS, RomRaider and other software supported besides TunerPRO RT?

You can use any editor that saves firmware in binary format (bin), and then using our utility you can upload data online using the "Live scan" or separately just as a file.

Does FlashOnline calculate the checksum?

No. You need to take care of this whenever you upload new data to the emulator.

How is this device connected to the ECU?

Поскольку устройство является эмулятором чипа памяти, то для  работы требуется установка вместо штатного чипа. Для подключения вам необходимо демонтировать штатный чип flash, и монтировать специальный переходник под эмулятор. Как правило это производится с помощью термо-воздушной паяльной станции.Далее вам необходимо подключить эмулятор к ПК с помощью USB интерфейса, загрузить full прошивку и далее можно производить онлайн настройку!

Do I have to use FlashOnline permanently after completing the tuning process?

No, FlashOnline uses the same firmware file as the flash memory chip, therefore, after the ECU tuning process with the emulator, you can install the chip back and write the necessary firmware (calibration) to it via the OBD connector, i.e. flash the ECU in the standard way.

Are there any analogues of this device?

Yes, there are several devices known to us that are designed for these purposes and ECUs. Today it is: Moates Roadrunner ( and EVC OLS300 (

    Все работает отлично, проверено на Bmw ms 41, настройка в режиме реального времени прошла успешно! Flash online + ms41 получается инженерый эбу. И тот факт ,что работа идёт с фул размером прошивки даёт намного больше возможностей чем работа с kess и аналоги по обд, где только можно залить калибровки, это особенно важно в работе с мс42-43.

    Отличный продукт. Все что заявленно работает на ура. Не хуже аналогов, а то и лучьше.
