When asking for technical help at the very least let us know the version of firmware you are running.

Hi to everyone. I have got a Vems unit from racecar that had an crash, case is brocken and oil/water get in. I am pretty sure that Atmega is dead. I am electronic engineer and i can replace the chip but i dont know what firmware was in it. Programing is not an issue i have programer for atmega128. PCB look like v3.8.
There is schematic for v3.8 on vems site and i checked all power and gnd pin to atmega everything is ok but chip is dead. Is it posible to just flash newest firmware?

You need the bootloader and you'll need to email info@vems.hu with the serial number of the board. Including a pic of the PCB so they know it's not a counterfeit would be a good idea as well.
