My 3W's (75i and-106) have a tach output on the wiring harness. The tach will hold the rpm value for you. I have the tach, it's a very nice tool.
Thanks, Dan767, that sounds like a really nice thing to have. Where did you get the tach? I don't have such a connection on my ignition harness but maybe I'll contact C-H to see if it's available. I'd like to have it.
