Incorrect Fuel with Tune

[Chubbiejones]

So here’s the deal. Purchased a 18 GT PP1 used from a local dealer. The car was tuned by the previous owner by PBD but I have no clue which tune is currently installed (I called PBD and they would not provide any information since I was not the person who originally purchased the tune). I’ve been running 87 with no issues for the past few months but recently filled up with a tank of E85 - let’s just say the car does not run nor shift as it should. I presume the car has a 93 tune and not an E85.

Should I drain the tank or drive till refueling is required?

Do you know for certain it's not the stock tune in the car? It's possible that the previous owner returned the tune to stock before trading it in.

In either case, you need to drain the e85 and put regular fuel in it or order and install an nGuage/Tune before driving the car more.

So did you just assume there was a flex tune loaded on the car? Most people are courteous enough to atleast return the car to a gas tune if not loading the stock tune before trading it in. Get the e85 out of the tank and get the dealer to flash it with a stock tune and start from scratch if you want to tune it

The car has a tune, currently has long tubes and CAI that requires a tune. Unfortunately this is a daily so waiting on a tune is not an option.

Not sure if presumed the car had a flex tune installed. The car has mods which require a tune so there was no way to reflash without removing the mods

The only way the car can run E85 is either with a flex tune loaded or an E85R tune loaded (which i doubt was). You need to drain the tank of E85 and put 93 octane in. Since PBD wont talk to you about it I would order an Nguage and Lund tune and let them know the situation

Personally, I would go to the dealer and have them reflash the computer back to stock. Leave the car at the dealer. Rent a cheap car and have a tune emailed to you on an sct or n gauge. This way you will have the car right. The dealer can clear the cpu with their Ford equipment. Start fresh.
Don't screw around with whatever is in the computer. Don't drive the car unless you KNOW exactly what tune it has. Many of us have had tuning issues with cars we KNOW about.
Ford will charge you $100-200 to clear and reload a correct tune. From there, you can begin.

I'm just curious, if you bought a car that is supposed to be tuned, why would you run 87?

They probably just wanted to see if it would run on 87,
They probably just wanted to see if it would run on E85
They probably just wanted to see it it would run on 93
What's next diesel?

Hahaha this gave me a good laugh

It is most likely on a 93 tune, If you are wanting to go E85, which I would suggest for the power gains it provides, hit me up. We are a dealer with PBD and can get you taken care of on a E85 revision. Lethalperformance.com

Did you also try running diesel?

Are you crazy? This is one of the craziest things ive heard someone do. Definitely dont run e85 on a 93 tune youll be way too lean and your engine will probably blow up. Also DEFINITELY dont run 87 octane either you are lucky your engine hasnt blown already. You can see what tune you have by looking at your Air fuel ratio in the guages, if its around 14 its 93, if its around 9.8 its e85 tune.


Depending on if you are on full e85 (filled tank from empty with e85) I would have it towed to the dealer, have them flash back to stock. You have to order a tuner and e85 tune from PBD for your mods then flash that on. I wouldnt even drive the car at all until you do this.

Prior owner is kind of a bastard for not including the tuner if he didnt return the car to stock and put the stock tune on.

Whatever you do, dont give it any throttle at all until you get it all sorted out. I really wouldnt even turn the car on until I had it sorted.

You took a ~10k risk doing this and if your car is still alive you are lucky

Yes, there was sarcasm in my question.

Drain tank, fill up with what you were running before, pull fuel line from rail and let pump cycle and catch fuel then re connect and let car idle for a bit to get the 85 out. You could also pull the rail and drain it for a piece of mind. Order a language and have lund send you a base file, datalog then get your flex and 85r tunes. Imho car has the stock tune still. No reason for the previous owner to keep a tuner that is still locked to that vehicle. Even though it has a tune required intake doesn't mean it has a tune. I have seen plenty of cars with a tune required intake running without.
