So I have wideband tuned the MAF and the VE pretty close, each seperately........... now throwing the maf/ve back together with the wideband still in, just in open loop etc to check they are working together i noticed that the dynamic airflow is dragging them both down for a better word........ now obviousily I need to probably just reign them both in a tad better BUT........ I never got an answer to my original question on another thread.
With the 'bluecat' VE tool.......... when you change the VE Table and spit it back out into HP Tuners it 'changes' the zone boundries and stuff on the dynamic airflow.......... ie. it uses that to reference what cells in the virtual ve tables, but it also then changes what cells it also references against in the dynamic airflow prediction tables..........
Now running custom os, people keep saying 'leave those tables alone' but I personally think we should be using bluecats tool, just to spit out the new dynamic airflow numbers....... why....... because it should essentially keep the calculations closer.
The dynamic airflow is clearly what decides what to lean on most, maf or ve while your driving in a mixed setup..... problem is, if you do mods etc.......... and you increase efficency at low rpm, it's still no difference if your up at 3-4000rpm on stock......... if your more efficient you should probably generally lean to whatever that section was meant to lean on..........
if you follow what i'm saying.......
I dont think there's been enough discussion really about the custom os, ve and dynamic airflow. I do see why people just run maf only, I mean at the end of the day it's only about getting the airflow/fueling as close to 'a target' all the time.......... and maf seems to be the easiest approach..... given the complexity of this stuff.
I'm just trying to wrap my head around it so i can run maf or mafless ........ without having to change the tune..... so for that to happen i need VE/MAF/Dynamic to all 'be right'.......
The more i dig, the more I'm considering just running maf despite wanting to go 'mafless'. Complicated.
I think mostly by changing the Dynamic Airflow from stock to what you've improved........ if you know your maf is stable in those rpm/map spots (for it to be beneficial), it will just force the car to lean more on MAF then VE.
