It's 20A per bank, as each bank has one mosfet. But it may need some more cooling, watch the heatsink.
You're right, I read something like that too, but... I think it's only interesting for engines with a high per cylinder power, which cannot be fitted with one injector of largest size. The ...

No, you got me wrong, I will not be injecting gasoline and LPG in parallel. The ground-line (the switched one) is connected in parallel to both, but the 12V line is only connected to one of both, depending on the mode. Using that you do only have 4 injectors per channel.
If I see it right the fets ...

In this setup it might be useful to use the MS2 to control some power transistors or mosfets which drive you injectors, don't know if the MS2 can handle this current itself while not in PWM mode.
What kind of LPG injectors do you want to use? I'm going to do a similar setup, but with LoZ injectors ...

Somehow correct, but EGO can also correct some errors that get into the system... like MAP slowly failing or something like that.
The EGO is of no use during accelleration/decelleration, as you cannot say to which rpm/map the reading belongs. Its mostly useful for tuning then.

The EGO is only a feedback after everything has already happened. If you don't keep the system stable (same load, same revs,...) once it determines the afr the combustion had... all the circumstances already changed drastically. The VE is the base, it works always. If the system is stable enough it ...
