The PCM would see the same traveled miles that the trip meter does,
unless you're manually correcting odometer miles in your hand milage
figuring (which nobody ever seems to do - they just bitch about big
tires stealing their mileage while not realizing that their numbers
are just now off by 20%) the difference should be seen in both.
