I have a wideband on a carbureted mustang. I run about 14:1-15:1 at idle and 13:1 at wide open throttle. Gets reasonable mileage cruising and runs strong and safe when playing. Jman is dead on in my opinion. Also they come with a bung to weld to the exhaust. You could put a bung in each buggy and use the same sensor for tuning on both. Just use a drain plug with the same thread to plug the one your not using it on.
