knock sensor circuit
 

what do you guys think about this circuit,
do you think this will work, or will it hurt?
the formula is; resister #1 - kn.sensor / 4,
resister #2 - kn.sensor x 2
Knock Sensor Desensitizing
The 4th gen f-body is prone to timing retardation due to false knock. If you suspect false knock is robbing you of power, you can desensitize your knock sensor with this circuit

to see the pic. of the circuit, click the
website, and go to techfiles.
sorry my computer freaked out and i could not
paste the pic. here.

any body!
what do you think?

I believe Nineball, who like me suffered from tons of KR, addressed this a long time ago. He came up with a knock sensor desensitizer circuit a long time ago.

sorry about that i did not know this has already
been addressed, i just singed on to this website
in march.
i would like the circuit info. if it is diffirent
than the one i posted.
how did the circuit work?
thanx!

Re: knock sensor circuit
 

i have been told that this wont work and will set codes but it is what i did several months ago and couldn't be happier.

i put 1 10kohm risistor inline with each knock sensor wire. i have seen no codes and my false knock problems are gone. here is a brief history of what i have seen.

stock knock sensor circuit with 6psi whipple>>knock every time i floored it especialy out of the hole and at the shifts.
10k resistor in each circuit with 6psi whipple>> 0 knock
10k resistor in each circuit with 8psi whipple>>full 8deg of knock retard continuas
10k resestor in each circuit with 8psi whipple and 100octane>>0 knock
10k resistor in each circuit with 11psi whipple and 100octane>>4-6deg of KR at the launch tapering thru the run.

all that leads me to believe that my knock sensors are working properly with the 10k resistors.

Re: knock sensor circuit
 

where did you get that circuit?
i mite want to try it too.
it looks like a good one
a lot better than the one i found.
