Knock counting, What's good
#241
I did see other people using the red lion counters, but at least based on the instructions you posted, I'd go with the Curtis myself.

Or better yet, get V-Knock from Vitesse:

The red lion appears to count in two different speed modes, 30Hz or 10kHz. The Curtis 703 operates at 500Hz, which seems better suited to the speed of the knock pulse. You are likely to miss knocks at 30Hz and pick up more electrical noise as counts at 10kHZ. I did a ton of work trying to replicate the Curtis knock counts using my own programmable hardware and saw first hand that the sample rate plays a very big difference in the final count.
