Re: Extreme rich condition
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..
