On a serious note, I picked up a $50 DMM with a Duty Cycle mode and patched it into one of my injector leads.... very interesting feedback (I think this is the scangauge/super mid feedback without the velocity factor.
My Vx shows 1% at idle.... 1.3% idling with the headlights on.... 2.3% idling with the AC on. Acceleration is as high as 30-40%... a good lean steady state freeway run is down in the 5-7% range (I don;t mean lean burn cuz I dont; have it yet... but that feeling when you get up to speed and back off the throttle to just barely maintain speed)... Oh, and any deceleration with the throttle closed goes to 0% as expected.
Pretty easy install... patch into A1 and ground the other lead. Reverse polarity since the circuit is ground switched.

Thanks for sharing that very amusing video. Much more practical than many of the gas saving gadgets sold seriously to suckers. You might want to post it to the general fuel economy discussion forum for more exposure.
