2013 Sonic RS Manual - 1.4L I4T E78, tuned, turbo mods, etc.
2008 TrailBlazer SS 3SS AWD Summit White - LS2 E67/T42, bolt ons, suspension, etc.
2002 Chevy TrailBlazer LT 4X4 Summit White - 4.2L I6 P10, lifted, wheels, etc.
I would like 12 MPG, since i can expect that, what should i do to improve what i am getting?
Driver slower, speed kills MPG, just because you expect or want a given fuel mileage does not mean you can have it.
Trailer design, towing while a head wind fights you, towing grades.........be happy its not a gasser.
I have had a Duramax since 2002, the best I got towing my 10K 24/ft V-Nose was 11.6, it got as bad as 9.9 in certain conditions.
Keep it at 62-65 mph, anything over that..........kiss fuel mileage BYE, BYE
But even at 60, I get 9 mpg, so again your "advise" of keeping between 62-65 holds no new usable information, My gasser gets 6-9 mpg pulling the same trailer. Someday i'll find what is the issue and i will report back, or if after all the tuning options have been explored and all the hard parts have been replaced i'll concede that my truck just gets 9 mpg and it is what it is.
Thanks everybody for your input.
Looking at the log, it seems you have low air flow across your MAF for some reason. You have a max of 47.83 lb/min at 3229 RPM. Should be 60+ lb/min from my personal experience. The boost is following desired within about 1psi. Not sure why your vanes are closed so much most of the time. It's averaging over 70% throughout the log. Is this a tune you are working on yourself?
