ALP errors, what's wrong with my device?

Happened to me about 14 months ago.

Would spaz out detecting "Poliscan" randomly.

I suggest disconnecting one head and see if the issue stops, if not, switch around which head you've disconnected and see if it stops.
If it stops spazzing, then you know you have a faulty head, if it continues after that, you have a faulty ECU.

In my case, it was a faulty head, had it replaced under warranty and haven't had an issue since.

Was trying to walk him thru a step at a time & not throw to many variables into the mix all at once to confuse him. Your suggestion would have been my next attempt, too.
