1. Engine --> Airflow --> Dynamic --> Set High RPM disable to 500rpm
2. Engine --> Airflow --> Dynamic --> Set Low RPM Re-enable to 400rpm
3. ???
4. Profit!
I don't think those old vortec computer have a high rpm disable. They are pretty much just MAF based all the time.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
My apologies, I think 5FDP is correct here. If the MAF is reporting correctly, I believe by default it uses filtered airmass only and only uses SD when the MAF is not present.
I believe you should be able to confirm this in short order by logging and graphing MAF airflow vs VE Airflow vs Dynamic airflow.
The problem is when I m logging maf vs afr error the data I got is irregular and cant do the maf calibration, Im trying to do this beceause I changed the cam and bigger piston diameter
