anyone else have an issue with the reading you get?

mine consistently will show around a 30-45 mpg average when i get on the highway for over 5-10 miles at a time. i know this cant be correct based on the hand calcs ive done and the mileage per tank i get.

ive changed the settings on the tune to account for the tire size i have on my sct and entered it into the cts also and still reads high imo.


:dunno::dunno:

are you talking about the instant economy or economy average. my econmy average is usually around 11.6 all the time and hand calculate i get 12.2 so its a little lower than actual. instant econonmy is like tge mileage coach and when you let off on the highway it goes to 60 something mpg and giving it throttle it dives to 5 mpg lol

Yea its on average right now. Short trips to work and back it was around 15 then I got on the highway a bit last weekend and now it's back down to around 20 with the city driving

My issue after the update last night, is that half of my original PIDs are no longer available!!!! There are a couple new accelerator options, but i'm missing FICM, Oil Temp., Duty Cycle, and more.

I'm beginning to really hate this product. This is the second update I've done and the first time, my screen went black after the install and Edge said it was a bad bulb. I've only had the unit 6 months.

Was at about 19 avg then drove 14 miles mostly all hwy to my parents place and the avg went up to about 26 then drove around a bit again not much stop and go and got to around 31 avg. Then on the way home 14 miles it got to 37 avg. No way that's correct
