I was tuning my car and all of a sudden threw 15 random CEL codes and began bucking .. this happened after I did an upload to teh map. I cycled the ignition and restarted Smanager - reuploaded the map and it was fine.

I did however have a datalog of that run and want to post it for anyone to explain how it could have happened. The car was bucking and a/f was super rich during that upload

It's probably from uploading the entire map while the car was running. You should only upload the entire map while the car is not runing and then the realtime update can take care of the changes from there while the engien is running.
