Does 2007 Nissan Maxima need the tach wire ran to the ECU/ECM to use "Tach Datalink only" on EVO-ONE?

I installed an EVO-ONE using the THAR-ONE-NIS2 T-harness in a 2007 Nissan Maxima w/Intellikey (obviously more connections were needed aside from the T-harness)...

My question is:

Do I need to run the tachometer wire from the Fortin 20pin connector to the tachometer wire at the ECU/ECM in order to use the "Tach Datalink only" option that's under the remote starter options via the FlashLink software. I thought some cars are getting this signal via the OBDII CANs. My Fortin install instrustions (Guide #17763) only had me connect to CAN-high and CAN-low on the OBDII connector.

I already set the datalink protocol to "Fortin" as I thought this would be required.

I realize I could just use "tachless" mode but I would prefer it starting using my tach signal. Tachless mode does work though(I used this mode to verify the bypass and remote start features were working).

To be clear, I have only tried starting the car with "tachless only" mode and i have not ran a wire to the ECU/ECM tach line yet as im not sure if it is needed.

So what do I need to do in order to use "Tach datalink only" mode? My guess is setting datalink protocol to "Fortin" and run the evo's tach wire to the tach wire @ the ECM.
