What exactly does the Push Start option change?

Question

I'm just curious what the Push Start option changes when enabled? Since this is for an 08 GMC Sierra, and the option still shows, I wonder what changes since I'm installing a third-party push start system. Does it affect the ACC/IGN timing, or something else? Or perhaps it's only for vehicles with OEM push start systems? I understand the manual doesn't say to enable it on this truck, but since I'm using the EVO-ALL for an off-label use, I thought it would be handy to know. Thanks!

If the option is not mentioned in your installation guide do not worry about changing it.

 

The options are generic, you could flash the module for a 67 Mustang and it would still offer you push-to-start
