Sorry, if I am asking stupid question.

But from the reading and understand I get from them is that.

V2.2 needs the flyback board, and V3.0 doesn't.
The flyback board is used for low impedance injectors. So if I am using high impedance injectors for either V2.2, or V3.0 MS board, I don't need the flyback. But if I am running the low impedance injectors then I MUST need the flyback board ONLY for V2.2 MS.

Am I correct above?

Now about the resistor pack, I thought the resistor pack is equal to the flyback board.
From what I read, the injector resistor pack is only need when using low impedance fuel injectors. This is because the low impedance injectors consume alot of energy (from the Megasquirt system) so if it is not controller properly, it will damage the injectors very quickly. So, the resistor pack is used to limits the energy provided by the MS system to the injectors. So if using high impedance injectors, resistor pack is not needed. same for flyback board.
Am I correct here as well?

I am still very new to these stuff, I am trying to figure out how to install my MS system to my eclipse and not destory things, so I been doing alot of reading. I hope I get it correctly.

Sorry if I am on the wrong track.
