subiseidl Posted June 11, 2019 Report Share Posted June 11, 2019 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 Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 11, 2019 Report Share Posted June 11, 2019 What ECU do you have? Quote Link to comment Share on other sites More sharing options...
Simon Posted June 11, 2019 Report Share Posted June 11, 2019 On the plugin Subaru units it is all ready to go just a case of turning the function on and tuning it to the engine. Quote Link to comment Share on other sites More sharing options...
subiseidl Posted June 12, 2019 Author Report Share Posted June 12, 2019 I was thinking that but for the version 1-2 it doesn't appear to be the case. Quote Link to comment Share on other sites More sharing options...

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. Quote Link to comment Share on other sites More sharing options...
subiseidl Posted June 14, 2019 Author Report Share Posted June 14, 2019 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. Quote Link to comment Share on other sites More sharing options...
subiseidl Posted June 16, 2019 Author Report Share Posted June 16, 2019 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. Quote Link to comment Share on other sites More sharing options...
