Tuning Block Learn Cell #0, 165 ecm/MAF

I was wondering if anyone has figured how to tune specific BL cells, with a 165 ecm and MAF setup. I am trying to get my light load and idle BLMs closer to 128. From scan data, I am at very low airflow, <10 gm/sec, and usually at cell 0 for idle. I was running in the low 120s, but been slowly tweaking MAF table #1 values down by 0.1 gm/sec, and making things linear, getting some improvment to BLM. I'm thinking this table is all I can do to affect cell 0 blms.

Just wondering what all other folks doing.

Many other basic mods. Continuous PROM tuning. Got traction, need reaction!

You're on the right track. As I've learned, the MAF tables are really the first and foremost tables to dial in.
