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

Question

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.

Answer 1

As Derek mentionned, there is no analog tach wire input on the EVO-ONE. The Tach Through Datalink refers the internal EVO-ALL receiving tach through Can-Bus and sending it to the remote starter via the internal datalink. We are looking at renaming the option "Tach through Can-Bus" or something similar in the future.

 

I noticed you mentionned enabling Fortin protocol. There is no protocols to enable with the EVO-ONE. If using the offline options, you will see datalink protocols that you could change but those options are not for the EVO-ONE, they are for the EVO-ALL. Use the ONLINE options when selecting options.

Thank you very much for your assistance guys!

 

I think renaming that setting would indeed help. If it had said "Tach through Can-Bus" then i would have known what that meant.

Answer 2

The Evo One does not have a tach wire. "tach through data link" means it sees the tach signal through the Can Bus.
