Never bothered to pay for instrumentation besides the basics. They couldn't monitor lean burn or accurately predict gas mileage, so I didn't see a reason. Vacuum gauge is an accurate reading of throttle position and engine performance. Because of the low gearing on the hx trans I would see better mileage with higher shift points with less throttle, but I've seen contradictory statements from expert hypermilers, my drive is 100% city and below 55mph for the most part
I had a small volt meter hooked to the secondary oxygen sensor power wire to the ecu to monitor lean burn. Secondary voltage would read .00 in lean burn. This was in a 96 hx that is in my signature
Not currently doing any Hypermiling or gas savings techniques in my current red hx, cost me $14 for my last tank of gas so kind of lack motivation. It's also getting extremely poor mileage, 34mpg. Both axles are shot and who knows what kind of compression the motor has left in it. The other black 97 hx I had and sold recently was getting 38-38mpg city but it was a low mileage car with name brand eco tires
This is what $1300 gets you these days for a straight HX that for whatever reason has a re-upholstered interior.
I do mostly maintenence modifications to my cars. Adds to resale value for the most part
