I am very much interested in pushing the envelope on my FE achievements - my current short-to-medium term goal is 60 MPG and eventually, in long term, 70 MPG.
BUT I sincerely don't want to be stupid enough to allow all sorts of damage to happen to the engine in the name of FE. That's why this enquiry.
Can I get some links for the diagnostic unit you are talking about? Any brands/models you can point me to?
