yea, just as the title says, can MSnS-E on a V3 board with the flyback circuit built run a mix of hi & low impedance injectors? I want to run the stock primaries (88 turbo), which are high imp, but all the larger secondaries I have found are low imp. Will MS have a problem with this? Thanks!

 

yes it will have a problem with this. For this sort of setup, I'd recommend using a resistor pack on the secondaries.

 

Ok, will this affect how quickly/how much the injector opens, or the precision with which it opens?

 

shouldn't affect precision, but can affect opening time.

 

Ok, when running differently sized primaries and secondaries, what should be used for req_fuel calculations? Average of the two? Just the primaries? Thanks

 

just the primaries.
