Which leads back to the question of how this can effect your fuel economy. Even if the available DC voltage is cleaner/smoother, how can it make the engine produce the same power with less fuel? Or more power with the same fuel or more?
The engine needs air, fuel and ignition, in the right amounts (air/fuel), at the right time (spark). Do we think that the ECU sensors deliver degraded data due to voltage fluctuations? Do we think that the ECU performs bad calculations from the same? Do we think that the car would run richer (wasting gas) as a result? Do we think that the stock fluctuations in voltage can cause the coils to deliver insufficient or mis-timed spark?
I don't belive that any of these things are happening without a VS, but I can't think of any other voltage related things that could affect the car's fuel economy or power.
