My son, who is not a gearhead, says I should be able to alter all the computer parameters on my car. This has to be related to this SCT you guys refer to. In the old days, I could alter my timing, mixture, fuel pressure, etc. and make my car my own creation in all ways. I must admit it was a lot of luck and perpetual adjustments, but in the end my cars were faster than my friends. Or, if traveling, I could advance and ease off the gas to get more mileage, etc. Where does a guy start for a tutorial in Lincoln computer geekdom? Which provider can educate me and provide the needed hard/software? If I'm going to make this my long-termer and sell the Mercedes, I want to be able to do it all from bags to that damn blend door.
