Bad mpg

[mrspades252]

Whats up guys, so i recently got my car dyno tuned, and also noticed that I am only getting 20mpg on the highway... Can someone take a look at my closed loop settings to see if its normal? How does the tune file look?

You will get low mpg if you are driving the car hard. Have you discussed the issue with your tuner?

Yes I have spunkster, i shot him a text about a week ago.. i was just wondering on your thoughts on how the tune looked and closed loop settings... what are your thoughts?

Based on the Datalog it does not appear to be running in closed loop as there is no long or short term trim.

hmm thats weird... the calibration shows that there is a long/short fuel trim.. it is on closed loop... i would assume that my wideband has been damaged.. i also forgot to mentioned that the wideband randomly goes lean and shows - - - (aem uego). That is strange....
