Well I sure do feel dumb right now. Went back and looked at the consumption correction factor and it's not set to the default 1000, but rather 0779.



That's 221 under 1000, presumably what it was before it was changed to 0779.
Perhaps unsurprisingly, after doing a little math, 221 above the default 1000 is just about the right number.


Looks to me like at some point in the past it's gone in for a service and they've made an adjustment, but the made the adjustment in the wrong direction...


Now that the number is where it should be, I'll watch the trip computer over the next week or so and see how it plays out.



Can't believe I didn't notice this before... haha


PS - Are you the Wayne who made up the great little video on youtube regarding the thermotop remote heater modification?
