Maf tuning issue
Hey guys, I have a 2000 Silverado with the 4.3l vortex. I have read and read and watched video after video on how to tune Gen MAF and VE. Everyone I see has me disabling DYNAMIC AIRFLOW by setting HIGH RPM DISABLE TO LIKE 400. My problem is that I do not have that as a option to change. So, me being only 5 days into this journey, how do I disable dynamic airflow on the 4.3l vortec truck system? Please any help is greatly appreciated, once I figure this out, I can start really dialing in this little engine. Just for context... This truck IS going to be swapped in about 6 months, this time is for me to become confident in the HP TUNERS software so I can tune the 5.3 myself. Thank you all for your time.

Please forgive me, how do I do that for you?

It's a vortec computer and not a LS based computer, so a lot is different. If the IAT sensor is not built into the MAF, you could just unplug it to tune both VE tables.
Otherwise I believe those are really a MAF based system and you can use your fuel trims to adjust both for part throttle.

Okay. First, Thank you. I did some digging( quick Google )and found that the IAT is integrated with the MAF. So tuning the fuel trims with a LTFL/STFL ERR TABLE BE MY NEXT MOVE?

Alright, I made some changes to the torque management and went and logged some data (see attached file), From what you fellas can see in the data, where do I need to start? I am lost at this point. I have installed the wide band and set up my channels.

So, I have played around with the tables and vehicle supported channels and graphs. Now my question is, how do I go about tuning using just the LTFT'S and the STFT'S ? , how do I go about logging and changing the VE only using the LTFT's and STFT's? As always thank you all for your time.Attachment 157797
