daeron Posted October 14, 2007 Share Posted October 14, 2007 First off, how the heck does it work?? I mean, there aren't any cables attached to the throttle drum, how does it regulate speed? Secondly, does it impact fuel efficiency in the negative at all? The only way I could think of that it could work would be through feeding the intake more fuel than it would otherwise at a given air flow, increasing the air flow caused by vacuum.. but I have NO idea if that's even close. IF it is, then it would mean that when cruising, you're burning more fuel than you would be maintaining the same speed with the throttle pedal. If THAT is the case then I want to stop using it now... Any info is appreciated.. and even if you don't know squat, sound off if you have factory cruise control! w00t! Link to comment Share on other sites More sharing options...
TomRhere Posted October 14, 2007 Share Posted October 14, 2007 The servo attaches to the gas pedal under the dash. As for fuel economy with/without using it, debatable.. Really depends on geographics of where one lives. Cruise is somewhat slow to react to a vehicle that has started to go up a hill, so engine is lugged a bit, then it's given more throttle to get vehicle back up to set speed after slowing down. But yeah, on long trips it can improve fuel ecconomy over not using it... Link to comment Share on other sites More sharing options...
BlueTrain Posted October 14, 2007 Share Posted October 14, 2007 Mine's an aftermarket one the previous owner put on. I usually don't use it on trips due to the hills and the way it reacts. Actually only time i really use it is when im driving back to Michigan and Im going across NoDak. Then, ya, it helps. Fuel economy is helped a bit too.
