Monsoon dub Posted July 15, 2018 Report Share Posted July 15, 2018 Hello, running a monsoon g4+ with bosch 4.6 Ohm injectors , what size resistor do I need to use or will the monsoon run both types of injector? Thanks in advance Quote Link to comment Share on other sites More sharing options...

julio.t Posted July 15, 2018 Report Share Posted July 15, 2018 Hi, Why the injectors with less than 2 ohms needs less ballast resistors ( 2.2 ohm) than the injectors on the 2 to 6 ohms range ( 4.7 ohm) ballast ? Quote Link to comment Share on other sites More sharing options...

It is because the lower resistance injector needs more power to open. The main reason for the resistor is to reduce the amount of current flowing through the injector so it doesnt over-heat. If you use a Low imp injector without a ballast the injector usually overheats and melts. Injectors with lower resistance of course are designed to handle more current so they dont need as much resistance added. Quote Link to comment Share on other sites More sharing options...
