unfortunatly it wont. The 02 sensor reads risidual oxygen so it doent know the afr or if its ethanol or petrol, lambda is still 1. Yes lambda 1 is achieved by 14.7 afr for petrol and 8.7 or so afr ethanol but the 02 sensor just reads lambda 1 then this is converted to 14.7 as most tune software or obd tools as they are set to petrol afr like all the tables in most tune software. like romraider or ecutek the target afr is all dispalyed in petrol afr regardles if you running petrol or e85

When I made the original comment I was thinking the car had been refueled with petrol and running an e85 tune

Stopped at work and checked out the car today. Nothing in the fuel system looks aftermarket (no E85 sensor). No RPM blip when I pulled back the cruise stalk. However, it did smell sweet to me and a buddy when I started it. Iím sure it would be obvious to someone who actually knows the smell but I donít.

Thinking of buying an ethanol test kit. Another option would be fueling it up with E85 and see how it runs.

It seems like itís much safer to fuel up a regular tuned vehicle with E85 than it would be to fuel up an E85 tuned vehicle with regular - correct?

Find a local with a e85 test tube, or a friend that's maybe a GM / Ford Tech that may have access to a Ethanol Analyzer they can put in the fuel for you.

If the car has a e85 tune, and its cold, it may be hard to start.

If its a e85 tune and has 91 in the tank it will be very rich.

Get a fuel sample from your car. In a liquid measuring vessel pour in water (20%) near enough and mark the level now add fuel sample(80%). Shake it up let it settle.If the water amount has increased in volume it`s because it has absorbed ethanol from tour fuel. You Can`t go wrong. Even added a video.

Don't even try to bother with siphoning the fuel from the tank via the filler tube, it won't work.

Your best bet is to remove the fuel pump fuse inside the engine bay fuse panel, start the vehicle and let it stall out, then disconnect the return line in the engine bay and use some 3/8 inch fuel hose purchased from an auto parts store to fit over the end of the return line and set the other end of that hose into a spare fuel tank. Reinstall your fuel pump fuse, then turn your key to the ON position without attempting to start the car and it will pump out about 3 oz. of fuel every time that you cycle the key on and off.

Have a fire extinguisher ready, keep any ignition sources away, and don't do it in a confined space.

You'll also need a fuel quick disconnect tool to release the connector before you can slip it off. Have some rags available as well to soak up any fuel spilled.

When you're done obtaining a sample, reconnect the return line and make sure to prime the fuel lines by cycling the key on and off a few times to get any air out of the lines.

Check for leaks.
