I will be replacing my current high impedence 460/550 setup with a 550/680 setup. Now, here is my question. I will be using a set of cleaned high impedence 550's from an 88 measing 12.9 ohms each. Now, as for my cleaned pair of low impedance 680's that measure 2.8 ohms each, I bought a honda/acura injector resistor box that is suited for 4 injectors. But after I got it, I tested it and found out that it is reading 6.8 ohms at each prong. After using a crude method of using a wire with alligator clips on each end to connect the injector to the resistor box, it measures around 8.8 ohms. I'm assuming that if fully connected by using connectors for a more secure connection, it "might" measure around 9.6 ohms or so. But the difference between the resistance of the 550's (12.9 ohms), and 680's (8.8 - 9.6 ohms), is what concerns me.
Should I just sell my resistor box and buy (2) 10 ohm/20 watt resistors for the 680's -- which should give me around 12.8 ohms, or will I be ok with my current resistor box?

This is what I have:

This is my other option of buying:

^^^Apparently there's some type of difference between these 2 resistors

 

I was running 2 low imp 680cc with the factory resistor box and they were working fine at the same time i was running 2 high imp 550cc and everything was cool,now i never checked the resitance in any of the injectors just bypased 2 wires for the high imp and keep the stock setup for the low imp 680

 

I would do the same.

 

Anything over 6+ ohms should be high enough to keep the drivers out of overload.

 

I was asking because I wasn't sure if the difference in resistance would affect injector staging. Thanks alot guys!
