I just noticed that when the engine temp is between about 125-170, the BLM is red with values in the 140s. However, once it reaches operating temperature at about 190, the BLM drops to the mid to low 130s and never gets above 136 regardless of engine RPM (1,000-4,000). Also, noted that the ECM goes Closed-Loop when the engine temp reaches about 100 degrees and stays in closed-loop mode regardless of engine RPMs. So, I think this is running pretty normal as near as I can tell. However, I noticed the vacuum practically never changes - stays at 21-22 no matter what the engine temp is or RPMs. I thought the vacuum would drop as engine RPMs are increased. Attached is my XDL log file. Can someone have a look at it and give me your opinion?
