Most newer cars already have a display showing you how efficiently you are driving. Usually this takes the form of a digital readout showing you miles driven per gallon of gas over 2 time-frames: short term (instantaneous) and long term (average). Wouldn't it be cool to add this feature to older cars?

 We've spent the last couple of months working with the community and doing our own testing to find ways we can improve M2. We're keeping track of known issues that will be addressed in the M2 Release here. In summary, we're doing a quick-turn prototype of our interface board to confirm that several improvements we've made are acceptable for production.
