2005 G35 Coupe/standard key
Remote start works great but no "cold start"
I know all about the 2nd cold start wire (green and white) on the ignition harness. I have the G35s GREEN / WHITE second starter wire powered via the flex relay output (H3/6) and have confirmed the viper outputs the juice during remote start.
No issues with the idatalink can interface
Still no remote cold starting. The remote start harness is wired as follows: Any advice is much appreciated

What happens? Do you have the cold start issue when started with the key as well? Does the car crank, and not turn over ? Try to adjust cranking time ? Also make sure you set the flex wire as starter 2 under the programming menu.

I have adjusted the cranking time all the way to 1.2 seconds
I have set the flex relay to option 3 (starter output) and have tested that the flex relay output is actually outputting juice at the proper time.
I have the tach wire conected to the tach output of the "idatalink" (same as flcan I believe)
After some advice from a BestBuy installer, I thinking the tach has something to do with this issue.
I just tried going tach less and still mixed results

Tach input is conected to the "idatalink" bypass module "tach output".
Perhaps I should change the tach input settings on the viper to "tach"
The options on the Viper are as follows 1. "virtual tach" default" 2. Voltage 3. off 4. Tachometer
So far I have tried virtual tach and voltage

hook up an actual tach wire not through the bypass.

Hmmm I was afraid you might say that. I hate to run another wire through the firewall but will if I have to.
Are there any alternatives? Any recommendations on the BEST place to get the tach signal?
Thanks so much for your fast response

I'm also reading about menu item 3-14 "tach mode starter release" do you know anything about this setting? Could this be a factor as well?
