So, I started to not comprehend what was going on after the first 9 pages of the OBDguino thread, and decided I would ask my questions outright.

Is it possible to make an MPG/OBD hybrid? I still want all the extra information from the OBD, but I plan on making an HHO cell, which throws off the MPG data if polled from OBD. The injector pulse is the only way, for HHO, to accurately read the actual MPG. Otherwise the formula used (like scanguage) inaccurately measures the mileage.

Beyond saying that I read it from a bunch of people, I cannot back that up. Just like you are all much smarter than I with the vss and OBDII codes/standards, the other people who I get my HHO mpg data from are far smarter than I am regarding that.

Does the obd read multiple o2 sensors?

Also I was wanting to do 20x4 to get more data. How difficult is this? And do I just need to recode the open source to get it to display?
