Anyone know the correct settings in EMU to read knock? I have a PnP harness which supports this, but do not know what sensor type or freq to choose.

 

bringing back the dead...also interested in this

 

What are the options? Maybe we can figure this out.

 

It would be great if you can tap an LED bulb that blinks when knock voltage is detected

 

the options are

resonant and non resonant

and then the frequency, not sure what ours is, i know my harness is supposed to be setup for knock

 

we need to know the frequency of it though...hrmmm

 

still nothing?...come on guys

 

I have the PnP harness as well. I think PTuning is probably the most versed in this matter, hopefully they will weigh in.

 

bump to the top...ive been doing research for about 2 days and cant find anything...someones got to know

 

so far this is the only link ive found that might be of some help

http://www.phormula.co.uk/KnockCalculator.aspx

 

and this one....so im thinking we have a resonant knock sensor at 6.5 hrz

by no means am i reliable for anything that goes wrong....im just trying to answer a question i need answered as well as other people with the emanage

 

well hell it might be non resonant...hopefully paul or ptuning will chime in

 

its non resonant and is the same as the 02+celica gt-s'.....still unsure of frequency

 

ill try that tomorrow, ill be getting tuned anyway. Ill mess with some of the frequency and see if i can get anything to show up

 

dude if you can that would be awesome.....i just cant get on a dyno around here quick enough....also make sure to list what else you have done.......like std bore or oversized bore...

 

Brining this back from the dead... Im hooking up my ultimate soon and have never found an exact answer on this. From what Im thinking, it should be non-res around 6.4KHZ (I have 89mm piston)

mayhelp somewhat

 

Soooo I randomly found this.... Our knock sensor is deff non-resonant -


Knock Sensor
Built-in Piezoelectric Type
(Non-resonant Type/ Flat Type

Now, we just have to figure out the freq at which knock occurs, which should be able to be calculated from the bore size...

According to that calculator it would be 6.4KHz - Ill def be testing this once I have my Ultimate in soon

 

sweet...let us know

 

better keep us updated
