Regany New Member 22 Member For: 5y 10m 30d Posted 04/06/20 06:58 PM Share Posted 04/06/20 06:58 PM Has anyone had issues with fualt codes coming up saying software Incompatible with ecm/pcm and lost comunitcation with ecm/pcm only happens under full load and full boost then a warming light comes on and says comms error the boost gauge on the dash goes all the way up even at no revs, has only started doing it after the tune and the tuner has looked over the settings he put in and said they were normal and is not sure why it's doing it. The car is a 2009 fg f6. Any information would be much appreciated Thanks.
