[Land-speed] Knock sensor placement on flathead!

[drmayf]

James, an interesting set of comments. Especially the last sentence. 
Paragraph 2R of the 2009 rule book says data logging may be used in any 
class.  Are you implying that use of that data log to tune away 
detonation in a vintage car should not be allowed?  If so, why? I 
understand that active detonation control via some sort of in car emgine 
management systen is a no-no, but data logging and then tuning to 
eliminate that are fair game. True? Not true?

Too much, or any to me, electronics in a vintage car with a vintage engine raises questions to a knowlegeable inspector or impounds official. Anti-knock is normally a function of computer control as we all know in our modern vehicles and because of it we get the best the engine in our vehcle can give in performance and milage. Good Luck
