Hi I have just started building my DIYPNP and I started wondering what was considered low resistance/high resistance.
Also if I have 4 low resistance injectors, the ecu specs state I can only power 2. Is this going to be a problem if they are low resistance. Can I use resistors to make the injectors high resistance?
Thanks.

Re: Injector resistance
I would use resistors.
Re: Injector resistance
Ok thanks for that. The factory harness has an inbuilt resistor. Tomorrow I'll test the injectors and the resistor box.
Is there an "ideal resistance"?
Thanks

Re: Injector resistance
I finally got around to checking the resistance and i got 2.5 ohms for the injectors and 3.5 for the resistor box.
Should this work fine?
Thanks

Re: Injector resistance
That should work OK. You just need to keep the current per channel under 5 amps.
