I went to the track Friday night to try out the new combo. I logged all the runs and tried to tweak the tune a little bit each time. With the 243 heads and 11:1 compression, I was scared to push the timing. One of the issues I am experiencing is a lean spot when I am stalling the converter at the line. I tried to compensate by adjusting the boost VE table, but it was still lean. I selected GM:AFR as one of the PIDs and it was commanding 14.68 when I am commanding .79 lambda in the 105 kpa portion of the main ve table. Confusing.
If someone could take a look at my tune and log files and provide suggestions on what I could do to richen up the afr when I stall it up at the line. Also, what PID should I selected for commanded AFR? Any ideas on where I should be with timing after peak torque?
Thanks in advance!
