lie-o-meter

[frkjr_2580]

hey fellas, how can I get my lie-o-meter to read more accurate? When I was stock it was pretty close +/- 1-2mpg. Now with the mini and dpf delete the lom gets up to 30 when I first fill up and it never drops below 24mpg. When I do the hand calc. I am just about always around 16-18. I'm running stock size tires, so calculating the tire size I don't think will help the lom be more accurate. I know it's never going to be perfect but I would like it to be at least close. Any ideas?

I've got the same thing with mine. It reads about 6mpg about hand calculated.

I just installed the SCT Livewire DPF/Cat delete a couple weeks ago and had the same issue, just not as bad. Mine was reading 20-21 mpg's the first couple of trips but here the last week or so, it seemed to have settled in to 15-17 mpg's. I hand calculated and its getting around 15-16 mpg's so thats close enough for me. I have had the tire size programmed since day one, as well. Give it a couple weeks and maybe it will correct itself like mine did??

I use the ScangaugeII for my MPG and other readings.
When my truck is stock the MPG is very close within 2%
When I program it with my Max Energy the fillup readings when I fuel up can be as far as 43% off.
The programing is not reprograming the fuel flow for some reason.
With the ScangaugeII I can calibrate at any fillup so that way accurancy of readings are maintained.
