Having looked at just the raw data from OBDII on a few vehicles; data format standardization there is none. Not between car makes, models, years or versions (ie 2014 Suzuki Swift vs 2014 Suzuki Swift S) - this would require either months (or years) of reverse-engineering, or unfettered access to auto maker's internal documentation (for some I know it's minimal). (Likely require partnership with the auto industry to avoid litigation.) If you pulled that together and offered it in a usable format.. Wow.
