This may not be the spot for this thread, but it is related to my engine tuning and modifications. My vacuum control cruise worked fine before I built the new engine. Now that I have the new engine in, the cruise does not work properly. When I engage it, the control overshoots, then it lets the car slow too much, then gives it too much gas and overshoots again. If you can imagine it acts like a lead foot driver, flooring then coasting below the target speed then flooring it again and again, etc. Has anyone run into this and if so, were you able to get it to work correctly? I have a much bigger throttle body then the stock one. Small opening of the throttle gives much more air to the engine. It there anyway to dampen the cruise servo module or change the feedback so it doesn't overshoot so badly?
