I switched to nickel plated copper busbars

    How do I read this data? Do I need techstream?

    I think Mendel posted the XGAUGEs back in #26. Those will work as-is with a ScanGauge II, and can also be (probably already have been) translated for use with the Torque phone app, and other similar things).

    i knuckled down and entered the X-Gauges for hybrid battery resistance values. Have set up the gauges to display the first four, but for some reason it just shows the gauge "name", not a value. Likely something absurdly obvious; it's been so long since I've had the ScanGuage hooked up. I'll give it another look tomorrow.

    Dr. Prius was already monitoring resistance so this is what I got from this morning:

    At Park and no engine running: Resistance between 20 to 21 milli-ohms

    While driving on the freeway: Resistance went as low as 18 to 19 milli-ohms

    And I still hobble along with ScanGauge. :cry:

    So that 80 mpg fluke just got a little flukier.

    Now I got 92 mpg on that same commute. It's a 20 mile bumper to bumper freeway commute normally getting 72-76mpg.

    Anyway what matters is my overall mpg. Weather has been getting chilly and I'm seeing low mpg at fast highway speeds. If it does drop I will accept that and just keep the nickel plated bus bars. If it gains mpg, great! I will keep track for the coming months and report my overall results.

    All nuts are torqued and I will not be opening up the pack for a long time. These module threads are apparently really easy to over torque and break the threads. I did a test over torque on a module I bought from ebay (for load testing). Over torquing will tear the threads very easily.

    I installed a harness to be able to charge the pack to 80%. Have not use it much but tests showed pack always tops at 80%. For now I just want to monitor the effect of the bus bars w/o interfering with the results further.

    I'm still not clear: are you able to fenangle the case off, get to the cells, without removing the battery from the car. I'd be interested to take a peek at ours, but don't relish complete disconnection and dragging it out of the car.

    There are nuts on the bottom side of the modules, so not as easy as it seems;).

    I’d be wary of doing bus bar swaps or module swaps in the car as voltage transfers are easier with metal:cool:.

    The pack does not need to be removed from the car at all. I just open the case, remove the module covers for the terminals and get to work. The v is designed to be very easy to access the pack w/o much work. Not sure about the other Gens.
