Anmyone using shift on time and rpm combined?

Thinking wire out from dealy(timer) to rpm activated switch. Once timer is triggered would power rpm switch which would either be at rpm and shift or shift when reached. Two wire swap would do it. With data logger dialing two together should be simple enough using digital channel.

Just a thought while watching newsmax tonight. Hell if not use going to set wiring up so it is simple plug and play either way.
