      Can't answer your question on controller but wanted to say I sure think you are correct in that the condensor and controller configuration in certain year groups could be "better".

      It doesn't get much hotter than the 100+ numbers we get around here sometimes and I have often looked for a way to duct air to the 325 that didn't go through the condensor first. But I worry more about battery use in the same conditions more than I do the controller. The pack gets heat soaked and it doesn't really have any cooling air.

      Hot batteries have a lot of extra "zoom zoom" but at a cost in longevity. Use of econ or normal is definitely in the best interest of all components.

      FWIW I rewired my motor fan so it is "hot" all the time. The temp sensor can turn it on and off at will. I never liked shutting the car down and taking away the cooling fan. I believe Solectria might have this arrangement on some years.
