Just want to ask, is anybody of you had expirience of using knock detection headphones? For example http://www.phormula.com/KnockAnalyserPro.aspx or something like that? Is it work right, is it helpful at all?
I would be very grateful for the advice, if you can say what kind of stuff you using when need to build spark angle table. May be conrcete url adresses or knock detection kits names.
Thanks and hope you understand my english
