The one thing I've never figured out on the MPG
setting, is what the difference is between "Diesel A" and "Diesel B".
Has something to do with how the manufacture makes the map
, I believe. My Excursion and my friends E350, both 7.3's, are DieselA. You switch between A and B and look at one of the values, might be fuel pressure? On one setting, the measurement will move when you press on the accelerator, the other won't.
I've been using EOT
, TFT, EPB, and LOD. LOD is engine load. EBP
is exhaust back pressure. I'm finding it a little more useful in driving in the cold mornings as it helps me understand when the EPBV is more closed. When I can "see" that, it requires a lot more LOD percentage to just get moving and maintain speed. Doesn't seem to change much until the EOT
gets to over 110* which today took about four miles. EOT
started at around 18* with this AM's temperature at around 20* when I started. My OEM block heater was on for about two hours plus before start up.
For driving, I'm finding that if I can be more gentle with my inputs, I can keep LOD below 40%, after the EOT
warms up and the EBPV
seems to be opened up. I've generally had mileage below 16MPG, hand calculated, in the winter months here in Wisconsin. Usually in the 13 -15MPG range. I've done two tanks above 16MPG with my change in driving as a result of the data I've been able to gleen from my Scangauge. Would like more data, and then apply what I'm doing to the warmer weather.
I track my data here...

Finally, the ECM does read MPH. That gets translated in to the analog gauge, which is, well, analog. I used the MPH setting on the Scangauge to compare against my GPS
, and I found out that my ECM is reading 55MPH as 56MPH on my GPS
. One can change the MPH value in the Scangauge to correct it for MPH/MPG readings. I need to decide what to do with my actual MPH as it's read in the ECM. I have 285/75R16 tires, and I don't believe that the ECM has ever been modified to change the correction factor. Thinking about the Autoenginuity for that in addition to possibly using it for other things.
