LS2 Cruise Control Problem
Started trouble shooting, measuring voltages, etc., and come to find out that the 2 circuits on APP are whacked out for use with DD systems. After reading a 2017 post on this forum with similar problem, I called Rosta tech, as they make DD's controller, that a Builder of car used APP and ECU from an 05-06 Trailblazer (LS2), with E40 ECU, same as GTO I guess, and it needs these voltages so can't be reprogrammed or changed. There aren't that many out there so DD & Rosta don't have a controller to mate with it.
Anyone have suggestions on most economical way to get a working cruise for my ELCO as its going to be a daily driver, I would surely appreciate?
