2g knock sensor vs evo knock sensor

[G-UNIT]

Guys,
My engine is tuned with an aem ems. I'm currently running a 2g knock sensor and was thinking of trying a evo knock sensor. Does anyone know if it is resonance or non resonance type? Check out this link >>

Why do you feel you need to change it. I understand a non resonance will be more accurate against PK, however to with EMS you can set frequency ranges to get around PK from engine noise not calibrated into the 2g knock sensor.

Last I knew 2g and EVO were the same. I have interchanged them for years with AEMs, dsm links and factory computers and have not noticed a difference. other then plug length. Of course a 1g is totally different and I use the 2g/evo with all 1g AEM's.

Yes and no. They are the same to an extent, they are interchangeable however the EVO8 knock seems to be a bit less sensitive perhaps sensitive in certain frequency ranges... Those of us who are running EVO8 ECU's in our 2G's have had to make some changes to the Knock filter maps to eliminate phantom knock around the 3000 - 4000 RPM range. I know it is a lot of digging but if you look into the "EVO8 ECU in 2G works" thread you will find what I am talking about.

Cool good to know. I know we make those changes on evos all the time depending on the combo. I know the voltage in the AEM logs looks the same but that is not frequency based like the stock ECU is.
