It won't let me look at the numbers on that one.

That's weird Ken. Keep driving and don't do a reset just yet. When you get to the point where you can add about 4-5 gallons, head back to that Mobil and top off. It takes 2-3 gallons for the computer to detect a refueling event and will begin to adjust the alky content all over again. I've had mine come "back on" and adjust many miles later, often days sometimes.
It's time Ken, It's time

I drove it all day today with no change to the ethanol percentage... I will see what happens when I fill up again.
Believe me, if I had the spare cash to drop on a Tech2 I would. I haven't worked since my accident back in October and now, since my wife works for the school, she is off for the summer = no extra funds for funs.... lol

So while driving today I let the torque scan run in the Torque Pro app and here is the results... no idea what any of this means just yet...
Also these show up in blue and say unknown...
Also the Transmission Temp shows up blue as well and doesn't work...

I reckon that the computer has adjusted but your app has not. Else your fuel economy will not improve at all.
Did you download all the GM specific ones?
Click the gear
Click settings
Click manage extra PID/sensor
Click the menu top right
Click predefined set
Select Pontiac GM Opal

Yes... I did that to start off with but some of them don't work... which is why I have been trying to figure out what's going on with it.
I don't know if it has something to do with the year of my truck or what.
I posted all the PIDs the scan found and haven't really dug in to research what those are.
I am also not sure what it means when it shows the "unknown" PIDs in blue...
More research for me.... Hooray!!!

Did you get the app to give the right info? How'd that tank of gasoline work? I reckon you'll need another tank or two to completely remove the alcohol.
My wife has been driving my truck, like she stole it, so the mileage on E85 is about like a winston cup car. I'm about to switch back to gasoline too for some tests. I can get Mobil's 93 for $3.19 a gallon as of yesterday.

Never could get the ethanol percentage to change. I'm on the second tank of 89 now and still reads 74.9%... my brother has another Bluetooth OBD2 adapter I am going to try and see if it makes Amy difference.
Haven't bothered checking fuel mileage yet as I have no way of verifying ethanol content so I figured I would wait a few tanks.

Did you try deleting the pids or whatever they're called and activating it again?

Yeah... I have tried everything I can think of... next step is to change OBD2 adapters and rule that out as a factor.
I tried E85 in my 12 Denali with the 6.2L.
first
I will preface this with: We tried E85 in my wife's newer Impala, and the fuel mileage dropped enough that it simply wasn't worth running it. Cost more per mile.
I did drop about 2 mpg on the Denali, but the numbers very much favor the E85 per mile cost in this vehicle. So I'm going to run it. It does seem to run better on E85, and the octane requirements on the 6.2L are higher anyhow. So compared to high octane, it's a no brainer.

It may drop a little more on the second tank as the alcohol content heads into the 70 percentile range. Right now you're probably in the 50s. But it'll feel even more spirited!
I tried to get my daughter to try it in her Impala but she doesn't understand how it might save her money no matter how many times we've tried to explain it to her. LOL
How many cents a mile is it costing you where you live Ben? I was running between .17 and .19 cents a mile until my wife started driving it. It's probably a buck a mile right now! She says she likes how it sounds and the pickup! I'd be afraid to see her behind the wheel of one like yours! Dale Jr, move over, here comes my wife!

Thanks...that allows a few more pids lol.
Oil pressure/temp, Trans temp, knock counts a few others.
I seem to be around $0.15 per mile on the e85, and about $0.19 cents per mile on higher octane gasoline. This is mostly country driving, and of course this is estimated off of numbers I have right now. Higher octane fuels around here shot up about the time I bought this truck. LOL.
Seems like if I am running e85 anyhow, I should just get a tune.....or a turbo.

I know Randy runs E85 too most of the time. Speaking of, hey Randy, where do you buy your E85? I might need to fill up down there tomorrow.

I filled up today with 89 octane at $2.789.
It was sooooo tempting to fill up with E85 @ $2.139... a $0.65 difference would have equalled $17.48 in savings on today's fill up.
But I want to get some good MPG numbers on the 89 and then I will go back to E85 most likely.

? I have the flex fuel sensor installed at the rail and wired to ecm. Input needs to be changed in tune.
No where close to jupiter to e85 up, turnpike wpb or on congress a few lights south of Northlake there's a racetrac with it < just found out about it a few days ago, probably closest to me

Thanks! I know there's a Sunoco out west near 441 and Okeechobee I think and there used to be a Racetrac on Lantana Road and I-95 selling it. Turnpike Shell stations will be more convenient, thanks!
