10k Resistor mod. does it do anything
have a few resistors laying around and was thinking of adding one to the ICP sensor. which it what they are selling on ebay foe $30 but i have a few already laying here. does this actually have any positive effect on how the truck runs? I know i'm not going to get a 100 HSP gain or 30 MPG but does it in fact have any positive effect. will eventually put on a good tuner but figures would try this if it has a good effect.

I'm gonna end up going with a tuner. just figured if there was a gain with the resistor i would do that till i scrap enough together to buy a tuner. well, no sense in doing it since not gains are experienced.

I also would not recommend it unless you want to create / find HPO leaks faster.

right I understand the concept
Im just wonder if the pcm is smart enough to correct high icp with a shorter fpw

You would be taking the tool (sensor) that it uses to tell just how much
pressure it has in the rail and lying to the PCM about it. So the PCM will
put in what it thinks is X and act like it really is X when it's X+10K resistor
value. In other words you have a X+ factor and the PCM will never know.
It's like telling the wife that there is $500 in the checking account when there
really is 600 or 700 but you have "fixed" the register to show $500.

EDIT : Before all the wives bite my head off I know that your all smarter than the PCM and would not fall for that trick.

I'm thinking rpm should go up If the PCM don't regulate it somewhere else down the line like rpm or ebp should both go up but how much idk
Maybe this resister isn't enough to upset things
