a few OBDuino for sale

[Magister]

Gentlemen,

If you don't know what the OBDuino is, all the info about it is here : OBDuino

I have one assembled unit with an Amber LCD display, I also bought parts to build 3 more, 2 blue like you can see here (enclosure is home made by tasdrouille) and one white like on the web page above. LCDs are high quality FSTN with black pixels, rated to -20°C. PCB and all components are RoHS compliant.

If someone has a supported car or want to test on his car, send me a PM! The unit&cable is $75+sh (about $15 with tracking and insurance).

It is for CAN bus only so 2008+ cars should work.

I can vouch for the good quality and features of the product. I believe I bought the first one. I've had it in my Elantra for two months now.

What logic and data does it use to calculate fuel consumption?

Does it use manifold air pressure and engine displacement to get intake air volume, and then derive fuel quantity by assuming stoichiometric ratio? Or maybe some other method? Or can it get injector pulse data from the OBDII system?

It uses MAF and VSS to calculate fuel consumption, querying the OBD2 PIDs, like the scangaugeII is doing I guess.

EDIT: if there is no MAF it uses MAP and engine displacement.
