What fuel injector tester would work on a low impedance fuel injector (Bosch Denso 199500-2160). I have bought a Allsun EM276 injector tester. It seems to only work on higher impedance injectors. Im looking to clean injectors off the vehicle.
The injector has a .8 ohms of resistance. There is a resistor in the circuit that has about 2 ohms of resistance. Would I need to add the 2 ohm resistor with the tester to get it to work properly?
I also have exactly the same tool with a different brand name it has worked on everything I have thrown at it.
Time and heat are the issue if for cleaning you are running continuously for longer than a short time it might be wise to use a high current rated metal cased resistor in series say 2 ohm 100 watt.

I don't think I tried using the OEM resistor in the circuit when I tested it. Hooking the tester just across the injector terminals I could hear the injector lightly clicking but it would not function with fuel pressure.
I will try and add the OEM resistor in the circuit and see if it makes a difference.
I tried using the OEM resistor in series with the fuel injector. The fuel injector tester i have will not open and close the injector with or without fuel pressure applied.
I did use a 9 volt battery to operate the injector briefly, fuel will come out of the injector.
I have ordered a different fuel injector tester, maybe it will work. it is suppose to work on all fuel injectors and fuel pumps.
The fuel injector tester I purchased which is a model BST406 works with my type of fuel injector. Now I can clean and test my extra fuel injectors. This tester also can check fuel pumps also.
When the tester is first turned on it has a option for fuel injector or fuel pump. I'm not sure if the tester can check the pump if it is in the car, but i know it can test it out of the car.
