2) what will happen if i will put high imp injectors into car which should have low imp ?

I am not asking what i need to do to make it work, i am asking what will happen if u use wrong impedance, plug and play, stock ECU. Would it run? Would it run lean/rich? Would it fry something?

 

anything electronic, when using the wrong impedance, can damage all components on the chain.

 

anyone tried ?

 

no. and don't.
