For less money you put your engine on a dyno and you tune it the old
fashioned way, using your ears as sensors and your brain as signal
processor. Quite effective. Expensive transducers won't really help you tune
on the road anyway and, IMHO, are not really required unless you are
developing, say, a new head of your own or do serious engine research, or
maybe if you ECU can actually use them.
