Received a response from Jerome on a few things. (Jerome seems to be the go to guy for answers these days)
Most notably:
So, no more complaining about it only working in range mode.
There's still some ambiguity in Jerome's statement. It may have been unintentional. He wrote: "Torque sleep and improved range for Dual Motor vehicles is included in versions 2.2.139 and later regardless of the selected Range Mode setting. However, the amount of this improvement will be increased by enabling Range Mode which has other vehicle control modifications in addition to the HVAC behavior."
What I'm wondering is, is he saying:
a) that the increased efficiency from torque sleep will be seen whether we are in range mode or not, but we will see even better range, due to the other benefits of range mode, if we use range mode or
b) that the increased efficiency from torque sleep will be seen whether we are in range mode or not, but that we will see even more of that increased efficiency from torque sleep in range mode, along with other additional efficiency benefits of range mode.
I am hoping it is a), but based on the wording, I don't think we can be certain.
So... I wonder if it works? If the "torque sleep" does as advertised then you should be able go against the P85 without either car in range mode and have similar range.
This will be the case if a) above is true, but not if b) above is true.
