WTH?

So I hooked up the Tech2 this evening and it showed a 3% ethanol content. I then unplugged it and plugged my OBDLink MX+ Bluetooth dongle in and started the Torque app and it showed 3.1%.

I guess yesterday it was still calculating after she filled it up. She did it right after leaving work and drove about 25 miles home. Then she drove it to work and back today and I checked it after she got home.

Still surprised that it's only 3%. The last 3 tanks have been Mobil premium, Mobil premium, and Quick Trip premium.

Was it the Torque PID that was working for you?

My parents have a rental, good to have someone else pay the mortgage for you while it builds equity.

Yes some renters suck, like the time that one renter decided to remove a fruit tree with out checking with us first.

My dad brought that thing back from japan, it was a gift from a dear friend.

He was not happy, nope not happy.

Good news is my house came with one, a Japanese pear tree.

That would piss me off too…almost as bad as what these renters did. Brand new walnut cabinets were painted like some mixture between fiesta-ware and a bad psychedelic trip at the carnival.
There’s no amount of equity that will make up for these kind of bad life decisions.

Had a new Delphi fuel pump installed today, seems to have cured her of the idle miss. And hopefully the stalling that happened a while back.

Paying the bill caused me to reflect a bit on shop billing practices. Don’t get me wrong, I was satisfied to pay the bill and put the problem in the rear view mirror. Yet it comes across as greedy to me when there’s a labor charge that’s probably 5x what the tech is being paid, AND the parts are marked up WAY above what anyone can pay across the counter at a retail parts store.

Yeah, I understand overhead, profit margins, and all that. But it leaves the taste of double dipping every time.

They're making overhead and all they sell is candles.....

Is my understanding correct, this generation -mine’s an 08- uses the virtual sensor that calculates ethanol from fuel trim data?

Correct, no physical sensor, the software calculates it. In my 07, which also has an 06 style fuel pressure management scheme, my virtual sensor is usually between 15-20% off the actual number in the tank.

FWIW- According to the shop manual, +\- 15% is within spec.

Looks like they did a good job of painting!

I do most of my own work, partially to avoid the high shop rates in my area. When I do take it somewhere, I have one shop that will let me supply the parts, and just charge me labor. Had them do a fuel pump swap on my Expedition a few years ago. I figured $165 labor to rnr the full fuel tank and swap the pump was a great deal, since about the only way to do it is to use a lift.

Every other reputable shop I've tried to use, won't allow me to supply my own parts, undoubtedly because parts markup is a nice chunk of their revenue stream. Aside from the money savings, I like to KNOW that the right part, from the right OEM supplier, was installed. I don't want cheap substitutes that might cause issues. I guess a crooked shop could always eBay what I bring, and still swap in a cheap knockoff. But I assume they wouldn't go to that much trouble.

That's a lot of nice cutting in. Pretty impressive, really.
