Tuning, however for now it looks much better than before.. the tuning the hone in on 128 should be when the car is driving on the road

Re: Extreme rich condition
 

I just watched the entire data log which the previous still pictures were from. The BLM's, both left and right, started out as a constant 128 but half way through the test, they jumped down to a constant 115. The entire log was performed in closed loop. What's up with that? What is the correlation between the BLM and the integrator?

Re: Extreme rich condition
 

integrator is short term fuel.. BLM is long term. when you start the car I will be in open loop for a set time, based on O2, running time and Coolant temp. so during this time BLM is locked @ 128. after that is goes to adjusting.. 115 is rich, but OK until you can get the car to a driving state and get some data while driving. I believe your tune is from Marc, talk him about what he would like in order to get the BLMs closer to 128..
