Duduglanza Posted July 29, 2019 Share Posted July 29, 2019 Hi, i have a question regarding resistor packs. what is the right resistor for 550cc 2.4ohm ( low impedance ) injectors? i got my rc 550cc injectors jn my hand and got two resistors that when tested for resistance its showing 1.2ohm each. can i use them or no? need a electric guru here Quote Link to post Share on other sites
Stu Posted August 1, 2019 Share Posted August 1, 2019 (edited) I use 4r7s when wiring up customers cars. 1.2ohm are too low, usually need to be at least up over at 6-7ohms total to not burn out injector drives. What ecu are you using? They usual state what resistance they will operate at. Edited August 1, 2019 by Stu Quote Link to post Share on other sites
Duduglanza Posted August 13, 2019 Author Share Posted August 13, 2019 emanage ultimate. Got An injector adaptor on it that includes resisitors is in it too... hence i thinks thats the reason i didnt fry the injector drives. When chekcing resistance on the adapter got 500ohms on each wire. Guess they are in serious tough. Quote Link to post Share on other sites
