Maybe a stupid question, but what about us 2.5i NA cars, think we could use something similar to this, and maybe monitor other vitals of the car. Just think this is an interesting concept, and think if it was offered to us NA 2.5 guys you could sell more too...? Also if it is possible what are some things that could be monitored, or important in a NA engine. Oil temp?, A/F ratio?, rpms, anything else?
