We just had the wiring harness and software update done today. The weather in our area turned quite chilly the last week or so with temps in the low 40's. The auto stop and charging weren't working that well with this change. Driving home after the upgrade we noticed the charge needle moving into the charge zone a lot more than normal and auto stop was working at every stoplight. We also took the opportunity to top up the gas tank. Keeping our fingers crossed for a mileage improvement! :-)
