Evening gentlemen (not sure if there are any ladies here)
Wanted to share this, as it is a cool DIY project that you could do yourselves. I enjoyed building it very much

Seeing as my FZ6 was long overdue for a throttle body sync I decided to start looking for some tools and do it myself. Reading bad reviews about the cheap Chinese vacuum gauges and mercury style ones being illegal in the EU, my mind started to wondered "why not digital?"

Looked at the price of a 4 channel DigiSync. Eeek 200$ is steep.
After looking for a while I managed to stumble on a Hackaday project for a DIY digital carb sync tool.

All props to the creator Dennis as this was actually quite easy to set up and it all runs of a 9V battery.
He provides full electrical diagrams, parts list, PCB files, arduino code and instructions.

After ordering all the parts, the PCBs and designing/printing a custom 3d printed enclosure I ended up spending about 100$ (I went with the more expensive PCB mounted pressure sensors)

Already tried connecting it to the bike, calibrated the sensors and it does seem to be working really well and seems to be very accurate. Could not do a proper sync yet as it is -20C (-4F) here at the moment. Getting the bike up to temp would take so long that I would turn into a human icicle. Will leave it for later, when there's not a meter of snow outside.

Thanks for posting. I had no idea the arduinos and displays were so low cost. If I didn't have my mercury stick I would probably make one of these. :)
