Rydrhard Posted October 9, 2007 Share Posted October 9, 2007 I have a 2000 Rt and have not totally agreed with Bob Lentini's zero=zero adjustment to stop low RPM surging, but I did it and it worked. Problem is the idle speed was always too high 1200+RPM. The air by-pass screws were always bottomed to get this RPM. I have set the TPS voltage to .336V and have about 1100RPM with the By-pass screws bottomed. I think that there should be a minimum air flow setting using the throttle stop screw and then the TPS is set to .395V. Then the TB's can be synched and the air by-pass screws used to correct idle speed and not be bottomed out. Does this make sense? If so how would one find what the minimum air flow setting should be? Only BMW knows? I hope this question has not been asked before. Link to comment
