Im looking into putting throttle bodies on my 172 in the next few months. I've seen that jenvey seem to be the main suppliers at a fair price. But then im going to need ecu,loom but that field i have no idea in. Anyone any advice, or even better done this and can tell me what ecu and set up they have used. Where did you get the mapping done? and did your car run with them on standard ecu to get you to place for mapping as i plan on fitting them myself.
