    Importing Wideband into EEHack

    I thought I had all this done correctly, but apparently not. I have an LM2 hooked up through my A/C port but I am having an issue with the conversion in EEhack. I have both the wideband and EE hack set at 0 Volts = 7.350 and 5 Volts = 22.390. The conversion factor must be automatic in EEhack and it comes up as 3.008N+7.35
    When I try to run analysis however it gives me trims that are off by 50-75%, which is not right, as it runs perfect and my narrowband trims are right on the money. Also when I view the innovate while driving it is within a % or two, and it appears accurate in the EEhack display before I run analysis. Where have I gone wrong oh great gurus?
    Thanks,
    Roy

    Its giving me grief about uploading the file. Getting this.

    I think the AFR#s are right when I analyze and look under power enrichment AFR, they are just all over the place under VMAF fueling. Is that just how it is?

    everything seems fine except that you might be trying to analyze wideband AFR in closed loop (which is a fairly useless analysis) and trying to do a percentage deviation without the AFR target patch in your datastream (since it doesn't know what your AFR target is). try analyzing it as not a percentage. if i do that with your log everything is 14:1-15:1 afr as expected. you should install the eehack patch set if you want everything in eehack to work properly (most stuff disables itself without the patches but i haven't really bothered with some odd controls like that)

    here is a graph of your wideband during closed loop, i threw injector pulsewidth in there too so you can see that the lean points are actually DFCO (injectors off during decel)Untitled2.png

    Steveo, thanks for looking at that, I got it figured out based on your advice. I wasnt aware there was a patch on the computer to make EEhack better, got it installed. Working on that knock. You did a fantastic job on this program BTW, very user friendly. Kudos.
