I have been working to smooth out a ve table and i'm not having any luck.
99% stock 6.0 with the 1% being a magnaflow replacement muffler that is all.
I default to sd mode, leave maf plugged in for iat, i have an innovate mtx-l (properly offset to match scanner to gauge).
If i use the gauge, my corrections using afr error results after the any sensor based changes are just horrendous. i can be running within 2% then when i apply that correction i'm suddenly off 10%.
If i use the Trims method by enabling stft in open loop then i get the values to come down and i can verify it with my gauge but it puts spikes and ridges all over the ve table. i'm currently running in maf mode because i couldn't figure out what i was doing wrong in the sd ve to get so many ridges.
I have heard talks of transient dx/dt filtering in the scanner but i cant figure out how to use it and the forum doesn't say much about setup. The vcm help file is useless, basically just lets you know the software has the feature.
Also heard talks about innovate sensors needing signal speeds reduced through LM Programmer software. Does changing the port speed through the sensor software really help that much? I never reduce log rates when using them with megasquirt or haltech, but then again those are better units than my stock sloth ecu.
My vehicle is an 04 yukon denali fixed awd with the lq9 (non-egr, and stock return-less fuel system) I do not have access to an awd loaded dyno in my area. i try to drive as smooth as possible without jerking the throttle. my best guess is i am still having issues filtering out transient data to give me steady state correctable data. Any suggestions to filtering transients out?
I attached both my SD file and my MAF file. I'm not exactly happy with the wave i have going on in my maf calibration either. I understand its not desired but its getting me the afr targets to get by until i figure out a new move to try.
Thanks,
Alex
