low impedance injectors

what i mean the standard injectors are high impedance and i want to run these low impedance injectors as they are the correct size for what i need


can i add in a resistor to increase the value to the same as high inpedance injectors and will the ecu drivers be ok with it

right thats the manifold and wiring sorted


added in 25 watt 4R7 ohm resistor into the system, the orginal injectors were 11 ohms and new injectors are 3.1 ohm with a 4R7ohm  25 watt resistor


with this set up will the injector outputs on the ecu be able to run this quite happily

Hi Neil,

Our documentation specifies a 4R7 Ohm ballast resistor for a 3.1 Ohm injector. Above Simon recommended a 25 Watt resistor. It looks to me that you have this right. When you wire each injector put the ballast resistor between the 14V supply and the injector.
