88351wtsi Posted October 5, 2015 Report Share Posted October 5, 2015 I really wish I knew how to adjust ignition and be able to "listen" for knock using MS2 on my white shp. I seem to have had more trouble with timing than with fuel. Link to comment Share on other sites More sharing options...
polarisman14 Posted October 5, 2015 Report Share Posted October 5, 2015 If it's anything like what I did on my Focus, you isolate the wires going to the knock sensor and tap into them with a scotch lok connector. On the other end you put a headphone jack then you can plug it into your radio and listen to what the knock sensor hears over the radio. Detonation is a very distinct sound and if you look it up on youtube plenty of people have done this. I got the idea from Jon K at HKS, he uses noise cancelling headphones with the same approach. This gives you the ability to listen for normally inaudible knock and tune it out--sometimes knock sensors aren't super accurate (the Focus one wasn't) and pull timing when they shouldn't.

polarisman14 Posted November 9, 2015 Report Share Posted November 9, 2015 Mike, What wires do you tap into for the knock sensor coming off the ECU? I'd like to do this to mine sometime soon as we're getting into higher HP and boost territory. Link to comment Share on other sites More sharing options...
ucw458 Posted November 10, 2015 Report Share Posted November 10, 2015 The stock sensor puts out a really low voltage that will be hard to hear. Try this. http://www.starquestclub.com/forum/index.php?showtopic=127345 Link to comment Share on other sites More sharing options...
psu_Crash Posted November 11, 2015 Report Share Posted November 11, 2015 I use a GM sensor.. I think. Bolted to the side of the block. The cable is run into a small audio amp like the one UCW linked to. Havent had this on my car in a long time. Time to dig it out and put it to use Link to comment Share on other sites More sharing options...
Shelby Posted November 12, 2015 Report Share Posted November 12, 2015 This video isn't apart of those lessons but it is very informative so feel free to watch it. It talks about heat and how it affects every aspect of your car and talks about how people try and deal with it. Watching this video really kind of had me feeling like I'm on the right track with my car. I want to thank you for posting this link,, it tells more then most will understand , tons of very useful info there and explains why for years I tried to get guys to go to 3/8" fuel line over the 7.5 mm we have now , I know it is called 8mm but metric is not an exact size when compaired to say 5/16" , every fitting fuel travels thru needs to be as large as possible right up to the pressure reg Link to comment Share on other sites More sharing options...
