I don't think this is right. The MPH have nothing to do with this MPG indication. It's solely based on the quantity of fuel that's been injected. The indication you see on the MPG meter is directly related to this signal. It is actually a MPG scale put on a fuel flow meter.
And there's definetely no 4 sec averaging/response time involved. Any change in trottle opening/load on the engine gives an immediate change in readout.
