will15 Posted November 2, 2018 Share Posted November 2, 2018 What’s the deal with these falcon knock sensors and the adjustment of the sensitivity it seems to be backwards of what the discription is. I know ford have a complex way about implementing there knock strategy, so what’s the best way to stop kr pulling timing when you definitely know there is no knock?.

Roland@pcmtec Posted November 2, 2018 Share Posted November 2, 2018 Just reduce the max timing in the knock retard table. Quote Link to comment Share on other sites More sharing options...
will15 Posted November 2, 2018 Author Share Posted November 2, 2018 What’s the table number I’ll have a look, but I don’t think that’s really what I want to achieved. I still want it to pull, eg 5 deg of timing if it dose see knock and not pull timing when there is no knock. They just seem to pull timing all the time even when there stock they pull heaps of timing. Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted November 2, 2018 Share Posted November 2, 2018 How do you know there is no knock? Do you have knock ears? They knock constantly when stock as the computer will keep adding timing until it does. Quote Link to comment Share on other sites More sharing options...

My border line knock and mbt tables are the same in higher load area’s so no timing should be added I assume. Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted November 3, 2018 Share Posted November 3, 2018 The issue is the phantom knock can be quite severe. How many degrees does it pull? You can adjust the sensitivity by I've personally never looked into this, it's soemthing you'd have to experiment with. 1 Quote Link to comment Share on other sites More sharing options...

will15 Posted November 3, 2018 Author Share Posted November 3, 2018 I can be running 5 deg of timing at say 10 psi and it pull 6deg, iv had -3 deg and it pull -8 deg 1 Quote Link to comment Share on other sites More sharing options...
will15 Posted November 3, 2018 Author Share Posted November 3, 2018 I have increased the numbers in the sensitive table in the high load areas and it has helped, decreasing it makes it worse. It’s like the discription is backwards, it’s the same with hp tuners as well. 1 Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted November 3, 2018 Share Posted November 3, 2018 Depends how the calculation works. It might be correct depending on how it is used. 1 Quote Link to comment Share on other sites More sharing options...

dat111 Posted April 19, 2022 Share Posted April 19, 2022 (edited) just on this. if i was to reduce the sensitivity by 20% does it = 20% less of X number, or is that just an on paper theory? (still running the NA sensor data on my NA+T just want to understand how that it works Edited April 19, 2022 by dat111 Quote Link to comment Share on other sites More sharing options...

I would reframe playing with it too much until you can get it on a dyno with some knock ears. 1 Quote Link to comment Share on other sites More sharing options...
