strat10 25 Posted October 25, 2020 Report Share Posted October 25, 2020 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! s4s33.csv Quote Link to post Share on other sites
strat10 25 Posted October 25, 2020 Author Report Share Posted October 25, 2020 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. Quote Link to post Share on other sites
