I would like to see a tool, or software allowing mileage calibration. I sell autel and a few other brands. I loose Angel sales to obdstar, xtool, obdprog and now godiag for the mileage programming capabilities. I'm a diagnostic tech as well as tool sales, and if mileage writing was introduced to my im508 for example, I would keep it, and even pay for a mileage specific upgrade.
There's several clients selling the im508 I sold them, to buy the less expensive godiag gd801 key and mileage tablet, or the $500 xtool x100 pad which covers key pdog, diagnosis and mileage.
