I've had check engine light come on mid ride, for other stuff, but for P0638 that time it came on at startup - which is what pointed me to the movement of the secondaries as these go through a cycle when you switch on ignition.
It might not even be the same issue again - could be MAP sensor fault since the had to disconnect vac tubes to change out TB'S, for example. Chances are though it will be TB related.
Have you considered investing $20 in a lonelec cable for tuneECU?
I still have a flip phone, don't text, etc. but I actually would like to learn about the tune ECU and what it can do if I ever meet someone with a Rocket that could teach me.
