high impedance or low impedance, that is the question
 

is there a way to use a multi-meter to check the resistance on an injector to know if you need a resistor box? I just picked up some 650's and dont want to burn them up with my resistor box. I also dont want to remove the resistor box and burn up the ecu

ORANGE CHICKEN FTW!!!!!

Low- 1.7 to 3.0 ohms (Peak and Hold Driver/Injectors) you will need the box.

High- 10 to 16 ohms (Saturated Circuit Drivers/Injectors)No box

thread jack :P

I'm switching to OBD1 on my CRX......Do I remove my resistor box?

I'm still using the same DSM 450's just adding a PO6.

no

Re: high impedance or low impedance, that is the question
 

Honda/Mitsu/Toy ECUs want to see a minimum of 10 ohms across the injector. If you do not have 10 ohms, insert 6.8 ohm Honda or Mitsu or Toyota resistor box inline pls kthx.

Re: high impedance or low impedance, that is the question
 

the resistor box is needed cause of the DSM 450's. it doesnt matter what ecu you use, you will need a resistor box with those

good. I'm getting closer
