ethanol content gauge
Got my ethanol gauge display set up, displays the output of the GM fuel composition sensor on an LCD. There is a seperate box that works with it and outputs a 0-5v analog signal for connecting to an ecu.
Handy to know what's in the tank for seasonal blend changes, and maybe some day there will be a rom patch for flex fuel
Some kinda crappy cell phone pics but you get the idea:

I was getting 82% out of the pumps until the first week of September, it dropped to 78%. Car ran fine on the same tune. Filled up today and got 70%, logged it and the AFR dropped .4 and I get 6 counts of knock starting around 4800rpm steady till I let off at 5600rpm.
It changes at different dates in different regions but just though I'd post what I ran into going from summer to winter blend.

hey I got a few questions for ya.
Ive always wanted to know the range on that sensor
Have you put E10 in your car?
If so was that sensor right or do you how low the calibration on the sensor goes?
Is that the intank or the Delphi in line one?
Just curious. Ive wanted to use it for a few things.....

Great idea...I may ask about it later as I am in process of converting my car to E85. I am hoping down here in TX that it stays above 80% year round...it is still like summer here...88 degrees on Oct 9th.
I wonder if the sensor can go to 100% with "moonshine".

I'd like to see the spec if possible. I could probably build one of these... Can you post them?
#15
Could you mayby list a step by step install as well as points of contact for parts purchase?
Would like to get one of these set up. Hard to track all this down... Thanks
