High BLM and weird O2 data


Recommended Posts

Hello everyone,

 

I finally got my data logging working, but the program Does crash a lot, ill have to figure that out. I was able to get a quick run logged. It was a pretty spirited run, and I have looked over the data and had a concern about the BLM and the O2 numbers. The O2 seems to be all over the place, and the BLM is hitting 155. From what I read that would mean a lean condition. The car feels good, and is pulling hard. I did replace the O2 sensor and put in a high flow cat about a month ago. I got both from PNM parts. I just replaced the Fuel pump a month ago also.

 

I am attaching the log. 

 

Thank you very much! This site has been invaluable for me and my S4S!

I did notice that the High BLM numbers corresponds with very low MAP numbers, is that the engine restricting Boost? 

 

I do peg the MAP at 2.24 for a short period. I also have the Red ship installed.
