VEMS no contact,need help

[Tuna]

Hi.

I tried today to upgrade my firmware but my computer died and now I have no contact with the box. would be grateful if someone could describe how to do the reset ? preferably with a picture of the pins to be jumpered.

anyone know where I can read in detail how to update the firmware with vemstune, step by step guide ? so I'm sure I'm not doing it wrong .

Vems plug and play v3.3

Regards
Johan

1) edit the file 'upload-firmware12x12.bat' in the 1.1.27 megatune folder. Change the line that starts with: tools\megaloader.exe to read like so:

tools\megaloader.exe firmware\vems12x12.hex -wE -c com1

where "com1" is whatever your serial port is.

2) turn ecu off. Make sure no megatune or other programs are running that might try to use the serial port
3) shove a bent paper clip between pins two and three of the serial connector
3) power on ecu. wait 3 seconds. remove paper clip and connect serial cable to your computer.
4) run the upload-firmware12x12.bat file. It will ask you to press a key to continue etc. The process should complete successfully.

done this loads of times. i have a serial cable with 2 holes bigger than rest
