@mac, Yes, accurate fuel consumption is read from VSS and fuel injector pulse width data. That gives you all you need. The formula you mention early assumes a perfect 14.7 combustion, which is not always the case (richer during warmup and acceleration, leaner during decel and cruise).

comment Why does a car's engine vibrate at start, despite the circular geometry of its component's dynamics
Not all cars do this, I6 and V12 engines have opposing cylinders that fire simultaneously and they are considered "balanced", at any RPM. But even still, we're talking about explosions shooting metal slugs at insane speeds: there's going to be some vibrations.

comment What is the difference between normal, platinum, iridium plugs?
Well, going resistor-less is something you have to do with consideration of all the extra EMI you'll get. I would think that higher boost levels might require smaller gap, not different plugs. Did you try that?

comment Tranmission fluid changing vs flushing
If you already flushed roughly half, I'd think your chances are good that nothing terrible will happen flushing the rest.

comment How to align wheel manually
Most cars have only limited adjustability, which is why aftermarket "coilovers" and camber plates are popular. Typically the toe or tracking is adjustable on the front via the steering tie-rods. Camber can sometimes be adjusted via the shock towers or suspension arms. Caster is, as far as I know, always fixed without aftermarket parts.

comment Can I reprogram my car for LED turn signals?
The resistors aren't that big of a deal, it's the energy loss due to heat from the filament bulbs that uses a lot of energy.
