tach output appears to not function

0 votes
I have a 2018 Wrangler JK, everything appears to be functioning correctly with the exception of the tach output. Am using the evo with the advanced keys push to start system. I was not able to locate a setting in the flash updater for turning the tach output on or off.

There is no tach option on or off.

 

If you meter the tach output wire on the evo when starting the vehicle what does it do?
