So float resistance signal goes straight into instr cluster, converts it to CAN, then transmits that to the gas guage I guess then.
I played around with the live data on my scanner. Seems like IPC and fuel guage itself are fine.
39% Lines up pretty well with guage here
IPC full test is pretty cool
(may have to click, on 3 dots and down load to see actual video part, not sure why)
DTE lines up
This test does 0, 25, 50, 75, and 100% on fuel guage
.
Forgot to take pic of 25% on scanner, but you get the idea.
Dead nuts there.
So I should be able to take pics of actual mileage, vs % fuel and guage reading that IPC is telling fuel guage to read with scaanner
If I do that progressively with trip odo, no way dealer can claim they can't find anything. I get a huge bump in DTE and guage reading
at about 1/4 tank, then it drops quick back to where it should have been after about 30 more miles.
The real question, is if float is bad, or design of tanks and float is bad and there is no way to fix it. The biggest issue when I do
extensive analysis and present to dealer, is getting past EGO's. Dealers do not like people that know as much or more than them, and/or
tell them how to do their job when they can't. I've already had it in to two different dealers, so not like I haven't tried.
