Lol. I use an ELM327... easy peasy.Um, I think you are missing the point. The real time average and instant MPG along with the moving over/under graph allows a driver to modify their behavior in real time and learn where and how to improve MPG. Tough to do that at the pump after the gas is gone.
OBD1 (On-Board Diagnostics) and OBDII are each connectors and families of serial communication standards. Both are two-way. OBDII uses CAN, ISO, PWM, and VPW communication protocols for sending serial data through the OBD connector. They all can be sent over USB or BT if those ports imitate serial ports (see ubiquitous ELM327 adapters and clones on feeBay and everywhere). But Elio would be better off sticking with the standard OBD connector and interface and let the buyer decide what interface adapter they want to use.
Elio has suggested somewhat offhand they may go with ODBII but cripple it so it's one-way only for "security". OBD1 is an obsolete technology so very unlikely they would use that. It would cost more money since it's obsolete.
