What is the difference between forged and cast pistons

The shapes on this drawing are exaggerated of course, but they're really there. Pistons are generally made in only two ways, cast and forged, although there are a few completely CNC machined pistons out there as well, especially in today's specialty market. Note that it is very easy to distinguish the two, by looking for material above the pin boss. If there is mass there, and more specifically, in the straight-sided shape of the forging ram, the piston is forged. These days injector behaviour at different voltages is well understood.

The speed of opening and amount of fuel delivered vary with voltage. Corrections are made in fuelling calculations to account different performance for differnt voltages at the injector. If what the Megasquirt ECU understands is the voltage at the injector is different in reality, then it is likely fuelling calculations will be incorrect.

This is why the battery voltage calibration needs to be correct in your Megasquirt ECU. The ITB idle air control conundrum Idle air control is generally a challenge with individual throttle bodies. This is from the sensitivity of throttle position. Why a dual wideband oxygen sensor? But really. Fuel injector flow rates become predictable with a referenced EFI fuel pressure regulator.
