I have a customer with an E38, Maffless in a Nissan Patrol, it is used in competition and has a manualised Auto. The vehicle is perfect except for in tight trees where the throttle is opened and close repeatedly rapidly, under these circumstances it will lean out to the state of a missfire, I played with the dynamics for a day with no result, I suggested the customer refit the MAF as it was my feeling that the SD was the issue, I'm glad to see that seems correct even if there is no SD optimum fix.
