Napalm
Caught the Bug
My old 2012 did about the same thing right after I picked it up after getting it re-geared. It started out driving ok then definately went into limp mode. Happened in Dallas traffic at a bad time of the day. Once I was able to pull over to a safe place I reprogrammed with the procal and all went back to normal.
You could also try disconnecting the battery for awhile.
I see. It doesn't seem like it's going into Limp mode, just because it's so quick. It's like the electronics go crazy for about 3 seconds and then it goes back to normal. It seems to be happening more and more frequently. Disconnected and reconnected the battery tonight so we will see how it drives in the morning.
On a side note, you have made the 1000th post in Onyx's build thread!
So here's a cake!
