I did... Its something that they're "working on" with no ETA. They suggested a DIY BOB connector with ms2 or ms3. It would have been $600+ and still would have required assembly and extras like GM sensors and the like. Its certainly the perfect solution for some, but I'm not one of them anymore. I've done it on two other cars, but I want to be able to hop in the car in any weather, hot or cold engine, pass an OBDII plug in check if needed, and only tune the car once per mod change.
Standalone requires many hours of fine tuning across multiple seasons and weather conditions. It took me over a year to get the tune dialed in on the yellow car. Every time I would think I had it, there would be a negative 5 degree morning, or I would stop at Walgreens after sitting in traffic on a 105 degree day and find it unhappy. Sometimes there would be months between issues, but it was always in the back of my mind. My customers generally appreciate after sale questions being answered and support when needed. I can't even begin to imagine the nightmare that selling MS would bring.
