Good to know all the details regarding cold temp tuning. I ruled out being able to adjust things during our 6 months of COLD. Now I've got a work around, if I need to swap tunes.

A big thanks to each of you.

Have a good one

Henry, this was posted in an earlier thread and "approved" by Bill too. If it's cold, it doesn't hurt to have a low Amp charger (about 2 Amps) on the battery anytime you want to change the tunes. It will keep the voltage at the level needed for a proper update to the PCM. Low temperature tends to reduce the voltage output of even a fully charged battery, and this is a "work-around".
