Injector Impedence Q

[DemonTSi at aol.com]

In a message dated 97-02-14 11:52:44 EST, you write:

<< The signal you want to send the injectors is a voltage level.  The 
 power handling capabilities of the driver will determine how many of 
 the injectors you can drive in parallel (As the power handling 
 capacity goes down, the voltage delivered will go down for a 
 commensurate current drain).  Many injection systems now on the market 
 drive 4 injectors in parallel (note that series connection will drop 
 the voltage across the injectors).  The impedance of this connection 
 is not all that important.  Consider it a "fan out" problem rather 
 than an impedance matching problem. >>

So what role does the inpedence of the injectors play? So I assume that it
would be safe to just get four injectors and run them in parallel...from the
original driver?
Hmm....
