do I look for next to make changes? I did a scan/record on my way to work today, got about 16minutes of data. I checked the results, and the BLM was definitely stuck on 128. The INT acted a little differently than before the lock. It used to change rapidly, and the BLM changed slowly. Now the INT changes a little slower. What do I look for to make adjustments? There was about 100 frames of data in a row where the INT was around 112-118, and the airflow was about 30-32, relatively steady. Do I adjust the MAF tables like I did before with the BLM?

IE new MAF=(INT/128)*old MAF

I worked on the tables a bit with the just tweaking the MAF tables via the BLMs, above or below 128 at specific airflows. Now I just locked the BLM to 128. There was only one section in this scan where I could pinpoint making a change based on the INT numbers. Other areas things were changing simultaneously.

Also, how much should I be changing the MAF numbers, since it is a finer adjustment?

Thanks for any tips.

I never really got into tuning my MAF setup a whole lot, i think i had some things that were flaking out on me(relays, MAF itself, some other stuff). So i switched to SD soon afterwards. The best thing i can suggest is, Use the same road and weather conditions as possible when getting info. Then just start experimenting by adding and lowering values GRADUALLY. Then get more data and compare.

Anyone else got some ideas? I will most likely make another scan on my car, before I make more changes.

I just would like to know the proper procedure to tune with the BLM locked to 128.
