304. Knock sensor.

[Haydz]

Hey guys. ive been trying to gather info on whether its beneficial to add a knock sensor like the 185 hsv's or if it wont make any difference/ be worth the money and effort to install one?

anyone put one on? or thought about it. if it may possibly have benefits ill be up for giving it a go.



edit. found this info one ebay

The knock sensors are piezoelectric microphones I've been told, even when the engine is not knocking, and there's a loose bolt or something that simulates knocking, the sensor cuts timing, Even broken engine mounts can set it off.

The only thing it does is cut timing kinda like when it senses knocking. Its not really essential to run one to protect your engine. Smart people would know when the engine was starting to knock and lay off it a bit anyway.

Umm your talking shit ! ....
A knock sensor when it is detecting knocking retards timing.
That is how hsv get 185kw from the 5.0L it pretty much just has a more agressive ignition curve so is more prone no knocking so they installed a knock sensor .
To answer your question yes it is a good idea if your going to run the 185kw memcal otherwise you dont need it.

Ahhhhh, NO. the ecu retards iginition timing when the knock sensor detects any pinging. fact is that the knock sensor will detect and retard the timing long before you will ever notice it as a driver. a knock sensor is like a insurance policy, might save your engine when things get a little to hot and your running a lot of spark advance.

yes actually, I have seen broken engine mounts set it off. Here's the solution to stop pinging: Dont run 91 octane in a car with timing to suit 98.

Insurance policy my ass, if you cant notice pinging or knocking when it happens, dont drive a modified car.

Dude under full load you are not going to react quick enough to pinging to prevent damage

yip damage happens well before the human ear can hear it . i like to run sensors for that little extra safety for when the car runs lean from fuel supply issues etc especially with commodores being bad for fuel surge out of the blue its great insurance against hard pinging when it runs dry going round a corner

[Haydz]

well i dont have a highly modified car in the least. basically just bolt on's and a greenfoam tune.

just trying to get the most out of my motor without opening it up really.

[delcowizzid]

its not gonna make any more power fitting one unless you planned on getting a tune redone by foam to be closer to the edge but hes probably got a fair bit out of it as is

if you drive a car around with broken engine mounts maybe you shouldn't be driving modified cars.

Not my car mate, but good point.
