    why does injector pulse width drop then go back up on start up?

    I have been messing with the start up on my setup and it starts fine, but I am wondering why my injector pulse width goes down for just a second then comes back up. Does anyone know why it is doing that, I have tuned multiple vehicles before and haven't had that issue. I have compared it with other files that didn't do that but haven't been able to figure it out. I would like it if it would just be a smooth ramp from when its cranking to when it is at idle in the first few seconds.
