Message	charts from time to time concerning lean A/F ratios and know that the programs are not the culprit - unfortunately everyone wants to blame the ECU first, and we both know that it is not the problem. There are at least 30 other candidates for A/F issues, but for some reason, everyone wants to blame the ECU first. The program responds to what the sensors are indicating of the engine's status and if your MAS is defective (or any other of the 30+ candidates), the ECU is still doing its job but the end result will be skewed because of "the problem."
