My recal software/firmware did what Wolfman didn't do at the D/FW meeting - dent my mpg. Had another one of those rapid recals.

I'm going to start paying more attention to when this happens - esp. when driving on the ramps onto the freeway. I'm over 90,000 miles but it's strange that it happened twice in a week in cooler weather and hypermiling.
It was no suprize that it recaled several times on my two trips in Colorado, esp. on long climbs at 75mph on I25. My first two years I drove it harder and recals were more likely to happen. The most likely scenerio for a recal in Dallas is aggressive freeway driving on a 100-degree day with the A/C on, then get caught in stop-and-go traffic and the final nail-in-the coffin.
