Evo all and 4105 avital remote start. 2017 toyota rav4 h-key. evo all programmed perfect, and remote starts perfect. diabled trunk option in evoall options, enabled unlock before start/lock after start. Everything works and car starts perfect. Except If i arm system with factory remote and then try to start, the car will just crank and not start. If i unlock the car with the factory remote before start the car will start everytime. even though the evo unlocks the car before start it wont work unless i do it with the factory remote first.

turn off D2 and re test.
works perfect with d2 off. why is that?
Is the TPMS connection required?  For that same vehicle?
The timing of your starter is off in the remote start sequence. The starter is ahead of us in the starting sequence. Try one of the following: 1- Hook up the dis arm wire with both the ground while running to give the evo more time. 2- hook up the analog dis arm wire from the starter to the vehicle.
