EcuFlash

From EvoEcu
Jump to: navigation, search

EcuFlash is a general-purpose ECU reflashing and editing tool that supports an ever-growing list of vehicles. EcuFlash uses the OpenPort vehicle interface to reflash vehicles via the OBDII port. EcuFlash also allows you to edit ECU data (known as 'maps' or 'tables') in a human-readable format using a XML-based definition system to translate the data. With properly setup definitions, the ROM from any vehicle can be edited.

Release history (from EvoM):

  • 0.91, 2005-10-25
    • This version has been created to support the new OpenPort 1.2. The OpenPort 1.2 has a 12V reflashing voltage that is controlled by RTS line of the virtual serial port which is off by default. EcuFlash now switches this voltage on at the appropriate times.
    • This is intended to be the last command line version of EcuFlash. Future versions under development use a GUI and are supported under Windows / OS-X / linux.
