When looking at my ECU tonight I just found I have 6 0.47 ohm resistors on my injector drivers (rb20det ecu, rb25 with 740cc deatchwerks injectors).

Now when I bought the car I had a wolf 3D and GTR injectors, I then had an r32 ecu installed and a proper resistor pack installed so this would have meant I was running dual resistors. Now I have 740cc deatchwerks injectors which don't need a resistor pack as they are plug in.

What would be the outcome of running 0.47ohm resistors on each of my injector drivers? I thought the GTR injector pack was 10 ohms so 0.47 is bugger all in the scheme of things.

This would ever so slightly reduce the current drawn by the ECU ever so slightly, would this negatively impact the way the injectors work? As they are essentially open/closed I can only see this affecting the actual opening and closing times, any ideas if this would cause issues?

Yeah which is why I am so confused, if you actually needed resistors they wouldn't work, and otherwise.. well I can't see them changing much.

Maybe they actually needed the 10 ohm resistors for the GTR injectors to not burn out the wolf 3d, but they didn't run it long enough to realise that their 0.47ohm resistors were going to do it anyway
