And people that don’t have a passion for it WILL never understand our love for it… It is no more a waste of time and money than playing Golf, or any other hobby…
For me as a carb guy, converting everything over to E85 makes no sense due to the cost, I can add boost for that price and be way faster, but on a late model already mostly set up to run E85, it is a no brainer… But in order to really take advantage of E85, you need to be running boost, then it will really show an improvement…
This modification to use E85, in what manner does this modification measure the ethanol concentration in the gasoline?
Tester
Flex fuel sensor
I know they exist.
But from that statement, it sounds like the modification doesn’t include one, which would mean engine disaster should the OP fill up with a bad batch of E85 which is actually E10.

@davesmopar ahh I wish I could go boost, gen 1 coyotes can handle something like 600 whp before the rods start breaking…in that case I’d have to build my motor or do a gen 2 swap both of which are too expensive for me at the moment. I suppose low boost would be an option but I’d still be paying the same amount and at that point might as well just start off with a gen 2 coyote platform instead. If money was not an object I’d get this motor built and boosted for sure.
@Tester I couldn’t tell you the how exactly but I do know the tuner writes the tune with parameters for timing, spark, etc. that adjust themselves based on ethanol content detected by the sensors.
The best way to avoid this happening is to just buy an E85 testing kit to test ethanol content before filling up especially for the first time at a gas station that sells E85. Maybe test every time before filling up if being overly cautious. However I’m pretty sure by law gas stations that sell E85 HAVE to get it tested on a regular basis for that exact reason and the minimum it’s allowed to be is 50% although that is somewhat rare it’s usually higher…so that’s why it’s definitely a good idea to test yourself
It’s not worth it.
If the modification didn’t allow me to run E10-E85 in the vehicle, I wouldn’t do it.
And now you’re talking testing the gas before you buy it?
Why complicate your life?
Tester
That is the other reason I am hesitant to pull the trigger on E85. Chances are testing every fill up is being way too paranoid and testing the same location you go to for E85 once a month is more than sufficient. I’ve never actually met anyone who blew their engine up from “bad e85” although I’m sure it’s happened before.
If there was some way to get a flex fuel tune I would have pulled the trigger a long time ago but I think I’ll just stick to regular 93 for now. Maybe i’ll try calling around a few performance shops that do dyno tuning and see if they could do a flex fuel tune
That would be your best bet, find a shop that does it and see what they suggest…
Your best bang for the buck would be a Nitrous Oxide System with jet sizes for an added 35, 50, 75, 100, 125, or 150 extra HP… just make sure your tune can handle timing retard or whatever…
That way you can keep the rods inside the block were they are the happiest…
There is no detection sensor with just an E85 tune.
Why not buy this kit which includes an ethanol sensor so you never have to worry about the ethanol content in the fuel
This doesn’t make any sense to me. It’s the alcohol in gasoline that is used an an oxygenate that has an affinity for water. Ethanol is hygroscopic and will adsorb any water/water vapor it comes into contact with fairly readily. Conversely, gasoline is hydrophobic and they tend to separate rather than mix. Regular 93 Octane gas will have less alcohol per volume (maybe 10%) so it will be far less effective at adsorbing any residual water in the system.
Notice the contradiction between these two sentences? Ethanol degrades the plastics but gas does not, yet gas is more aggressive solvent?
Exactly.
I’m soo glad we found confirmation that our 2020 Connect can in fact run either regular fuel or flex fuels and you may have seen my post earlier where I could get anyone to answer to my flex fuel questions. even Ford couldn’t tell me. But reading the owners manual and several online sites shows that our van can run just fine with the eFuels even without the yellow cap or signs/stickers within the van.
What a gain this morning. I laid down some rubber for the first time since owning the van. According to the spec sheets, the 2.0L I4 van comes from the factory with 162 horse power and 146 torque. Spec/research sites shows that one can see gains of 5%-15% in the HP & TR while using the eFuels and I’ll take that.
Tis the perks of owning a “commercial” van and using it as a daily driver, with more tunes coming up in the near future.
You never responded: does your van really have a gas cap?
