How does the ECU detect knock from the knock sensor? Is it just an on off switch signal or does the voltage vary depending on the intensity of knock? I'm wondering if there is any way to tap into this and data-log it using one of the aux inputs of the F/IC. I currently don't have any problems because I'm M-Tuned but it was just an idea I was throwing around that may help the community.

Even if it's not possible to get the F/IC to datalog it, it should be able to be tapped and run to a volt gauge to watch while you tune. This would help the 05-06 F/IC guys dial in their timing maps a little better since the 07+ apparently protects itself pretty well against knock.

Any ideas or experiences welcome.

I wonder if you an use this in the ultimate. I k ow in the ultimate there is a option where you can see knock. But it doesn't read good onthe Tc. And so maybe tapping the wire in the ultimate harness to the oem knock sensor. Wonder if that would work. Mike try it! Lol.

Ive had it working....?

What about the ultimate!! I think I'm gonna have to be a the project person

cburgle did it but threw a check engine light...I ment to try it out but other things got in the way, i dont have anything this week going on so maybe ill try something. If nothing els get some sort of a base line in stock form.

yes i tried it, and it was getting readings but i was thrown into limpmode and check engine light came up, somethign bout knock sensor low voltage or something, anyways it needs to be tried with a resistor or diode

ElevationTC

diode son diode

cburglb34

i mean i woulda soo been down to try it again with a diode , but im now pro tuned and my wiring harness is never being touched again seeing as i hardwired it in and dont wanna ever touch that thing again

lol maybe if i had a pnp harness that had miles of wires to mess with id do it but not gonna risk ____ing ish up
