You really need to go back to the dealer and try and find out what your base map is, may not give you an answer to the problem but it will cut down on the possibilities of what it could be
Yep I hear what you’re saying but the standard maps are just not drivable enough, SMC Slough were very good and sorted all the problems bar one that the dealer the car came from would not even attempt. I'm constructing a letter to Ford asking for an explanation why Marlow Ford is so unhelpful and clueless. Have had a custom map put on the car since and its drivability is now where it should but the limp mode has been back once seems it is nothing to do with mapping. We are now of the idea the ECU is getting to hot as soon as the car cools down the problem goes. We are going to move the ECU from between the engine radiator and cooler in the New Year via a custom bracket to a new position with cooler airflow
