EJ20G knock setup

Recommended Posts

I've been learning a lot about tuning from the hp academy courses and was gonna setup the knock control on my car when I noticed that the OEM knock signal isn't listed in the ecu pinout. Do I need to wire in a knock sensor to one of the digital inputs on the expansion loom. Thanks

I was thinking that but for the version 1-2 it doesn't appear to be the case.

Provided it is actually a G4+ WRXV1-2 ecu that you have then I can assure you it is.  It is not listed in the pinout because it is not a user configurable input or output, it is dedicated to knock only.

now I think I'm getting it figured out. So i set the frequency to 13Khz and a gain of 7. I've been running this map without knock control for a year on E85. I'm still learning alot so any feedback is much appreciated. Also the reason I didn't think it was working before was because with a gain of 1 it wasn't picking up anything. 

So do I need to setup the individual cylinder gains for #3 and #4 cylinder to bring them more inline with the rest.

so with a gain of 5, cylinders 1 and 3 set to .7, and cylinder 2 set to 1.3. I also installed a brand new knock sensor. I did a 5th gear pull. I'm on e85 and I know that the oem slanty intercooler is inadequate. Here's the results so far.
