Unless Jake is able to do a local tune when he is in Chicago, you will have to do a remote tune. Their shop was moved to Houston. If someone in the Chicago area has the cable and a laptop, they could drop by and away you go. I am waiting on new cable myself...old one no longer works.... There is a way, to have more than one tune. EC sells a device that will do that for you... There are other vendor agreements out there, but I think the closest shop would be north of Columbus OH....
