I have a 2014 Silverado with a 5.3 Bone stock. In the tune all that has been done is disable DOD, trans tune using the bluecat tool and slight changes to driver demand table. After lot of reading and learning ive set up several graphs to try and log VVE error in the scanner. The graphs "VVE CL", "VVE w LTFT" and "VVE w STFT only" are set up with math from Cringer. The 4th graph, "GMVE STFT % error", is setup using SmokeShows math for dual MAF and VVE tuning. I have made sure each channel needed for the MATHS is logged and set up with the correct units and all 4 have a filter for transients i allso got from cringer.
If you view the screen shot/ logs you will see that Im getting what seems to me a pretty large error in the graphs for a bone stock truck. So here is my question... dos that look normal for VVE to be that far off on a stock truck? If i take the VE airflow reading and multiply it by the Error value in the graph it dos get it pretty close to Dynamic airflow reading (most of the time its a little high).
NOTE: Im not sure if the math will load when you open the log file. At first im just going to upload the two logs and tune file if the maths expressions are needed let me know. And if anyone is wondering why im doing this on a stock truck im just trying to get a grasp on how to do it. Thanks for any insight.
