Most ecu's have this function, remaps can even do it. Neither here nor there. I just ordered a mx5 setup from Adaptronic for a turbo steup we are doing and the service outshone anyone (had ecu in my hand within 20hrs), i wanted the new ecu to have a play but the customers budget dictated the older one so i will live with the connectors this turbo setup should really give the ecu a workout so we will see how we travel.
