Batch firing 4 secondary injectors?
 
I'm working on putting together a reliable and precise 100% methanol injection system to displace 20-25% of my gasoline, as suggested by Defined Autoworks. Basically, I want to run the standard 2 primary injectors, but have 4 secondary injectors for a total of 6 injectors. Two of the secondary injectors will be for gasoline, the other two will be used for methanol fed by a separate fuel system. My question is, can I batch fire two low impedance fuel injectors off of each secondary fuel injector output?

The reason I ask is because I remember reading somewhere that the LT-8s can run 8 high impedance injectors or 4 low impedance injectors.


Any knowledgeable input would be appreciated,
Thanks

It should be able to batch fire them, just add a 10 ohm, 10 watt resistor to all four injectors, to lower the amp draw.
