i will be watching this develope! im excited. from a user's (id love to program but need to go to school for that) perspective this is what id really love to see in it.
gas mileage, money spent on gas in a months time, oil change alert, air filter change/clean or for me Recharge as i have a k&n cold air intake. and tire rotation alert.
what would be nice is for you to be able to set the interval of the oil change, air filter change and the tire rotation alerts. for instance.... i have a mustang and i like to change the oil and tired every 3,000 miles and clean the intake ever 10,000; however my dad does his oil ever 7,500 and his tires ever 5,000 so it would be awesome to be able to customize that.
but im not picky im just throwing out suggestions. id be happy with. just the gas mileage lol haha...
good luck to ya man
