FPR Shim and 10K mod

[Jake]

yeah, i guess i didn't think it would have that much effect on it.

here is a crappy little schematic i just made up for it.

One other point about the FPR shim, wouldn't putting a copper BB in the fuel be a bad thing? Wouldn't it eat away the copper?

Well somethin like that. The plug would be the icp sensor? in that case we're trying to disrupt that connection and get a desired resistance. so the on/off switch wouldn't be needed if we're just changing resistance to play with oil pressure to the injectors by tricking the sensor which tells the PCM to change it. And it would still be a closed "circuit" so other wires wouldn't be needed cause we don't got any external power to the sensor. and the wires from sensor into the cab to the lil box would be resistance to take into account. Remember everything is meant to run on a certain perfect spec so every little bit WILL effect it, even resistance in 6ft of wire... right?

In reality playing with the sensors is just telling the PCM lies to make more power just like a boost fooler or something. LOL!

Got me. I just learned what THAT one was today lol! Thanks to this thread

yeah, the plug is the ICP sensor. The switch is just simply to go back to factory spec if you wanted to, you could just cut the resistor out of the loop with the switch off. Basically the longer the wire the more resistance, so you would just have to use a different resistor, i.e. you might use a 10k resistor to get the same effect as a 5k without all the extra wire. not exact numbers, just example.

holy crap, its 4:10 AM. we can continue this tomorrow.

Oh I thought the potentiometer created the resistance so it would just be putting the wires in and doing that instead of a resistor and then just reset it back to stock or unhook it (switch right...?) It would help if I REALLY understood wtf a potentiometer does.

And that's fine I know it's late LOL, I'm a night owl.

[binder man]

and what makes you say you have to splice on an OBS? I did it to a OBS and didn't have to.

and adding wire increases resistance so wouldn't putting in a 10K with the potentionmeter be like a step down from regular 10K? say 18Kish to compensate for the wire and switches now?

[redstroker_2002]

ya i picked up a 10k and 5.6k and i got the 10k in now. that 5.6 is way to loopy. good to have it for s hits and giggles though
