    Posting #2 looks like two ("2") screenshots of Torque Pro which is what I use. First screen shot in posting#2 lacks "HV Charge" and "HV Fan Speed". However both screenshots have "HV SOC". First screenshot shows HV SOC at 66% while second screenshot shows SOC at 44%.

    Both screenshots show HV Block1 being about 6/10V lower than the rest of the cells. Looks like there is an issue with HV Block1. I have not rebuilt a HV battery pack yet but HV Block1 appears to be the first issue arising.

    Has mpg or performance been affected by HV battery issues?

    You will need to deal with block 1.
    It is acting much differently than the rest.

    I an still averaging 53mpg and no issue driving what so ever. I got that dreaded check engine and red triangle. Am I ran all these test to see what's wrong. Anyways the dash signs went away and it drives fine, bit I opened everything up to clean the HV Fan and now I figured if I need to change a module, I might as well do it now.

    What you guys think, should I just go ahead and change the 1st module and get something that comes out to around the other modules, maybe off by .01 or .02

    This way I wouldn't need to worry about equalizing it. You guys have more experiance, pls share your thoughts.

    also I'm not quiet sure what to make out of the internal resistance on the bottom of the pic on post #1, do i need to be concerned about those as well?
