[Diy_efi] Knock Detection by J+S

[bcroe at juno.com]

Bruce, 

I know the J+S retards individual cylinders to maintain as much 
power as possible.  Since there is no cam sync, it can't tell you 
which cylinder that is, but it will give the max amount of retard.

Just what else is done to "look for knock when its likely"?  I was 
thinking of paying for an Accel 7 knock detection option, but I 
am leaning toward using my J+S system instead.

thanks, Bruce Roe
