E85: why aren't more folks running it?

[dubster99]

Because the dealership notes in the service records whenever they flash the pcm. If they see it's been flashed a few times and they have no record, they're gonna know.

Now I'm confuzzled. Why does everyone get their man-panties in a bunch about voiding their warranties when the dealership can't discern why the PCM was flashed?

Do you think "everyone" actually knows any better?

Key cycle count also gets reset when you yank the battery..., and no they won't know.

then you'd understand incorrectly. The pcm is reflashed for many reasons. Such as warranty pcm updates etc. If you look at the published internal documents all the dealer tries to do is look for proof then get you to admit to it.

So what you are hearing is from people who have no idea how the pcm works.

Yes Ford can see key cycles since last flash, no they don't know why it was flashed.

Yeah but if it was flashed at a dealer due to issues or updates they should have a record of that, even if it was a different dealer..is that not true? If I show up with my pcm showing 2 flashes or so after the initial, I would think any smart service department would recognize what im doing. Im almost positive that ford corporate makes the ford techs check for evidence of a tune, as part of their diagnosis, in the event that someone comes in under warranty for powertrain issues.

Im not afraid of the dealer finding out about a tune, even if I had an issue that was motor related. I know they most likely cant prove that the tune had anything to do with whatever the problem would be. But you know they will try and void it anyway, and I don't really want to fight a legal battle over it.

A friendly dealer is the way around it but unless I find one of those, I gotta play safe for a little

the 14 ones are the short style. you need the injectors from a 2005-2010. lu47's

Same style. Lu47 works for the 15

I had some from a gt500 and they wouldn't work. I wasn't sure if all 11-14 were the same as those

Gt500s will work. They'll need a spacer. But they will work

Id1000s are short injectors (ev14) but they have a cap on them as well.

The lu47 is a ev6.

So if you yank the battery, it gets rid of the flash count?

 

[Process]

It's not a flash count. It's a key cycles since last flash.

A ford tech can only see that using mode 9 data on their ids.

Their only prompt to look for it is if the car has a passive p1000 code. If the car lacks this code they will not look for it period. Yanking the battery or a flash can cause this.

Even if it has an oddly low key cycles since last flash this proves nothing. They will then look for evidence of mods or just try to get you to admit to it.

 

[dubster99]

Interesting. Thanks for the info. Everyone else called it a flash count.

Good reason to run e85. This is with 15psi. Got spark?

Seems like more folks are concerned with immediately swapping to FI to make power as compared to really honing in on the power the engine has sitting on the table from the dealer lot.

Although I'd guess it doesn't help that you have worse gas mileage and less readily available fueling stations, combined with the fact that without testing constantly, you run the risk of damage.

Actually E85 is far less risky of damage than gasoline.

Its just that the engine needs to be TUNED for it.
E85 requires about 30% more fuel, so the engine must know exactly what its getting.

Its relatively easy to plumb in a flex fuel sensor that measures E85 content and the output of that sensor increases the fuel mixture.

I have it on my race car and it works a treat.

We picked up around 60-80 hp running E85 and all the temps are WAY down.

It really works for drag racing or time attack situations in my view, as any longer time format racing - you will pay a weight penalty for carrying extra fuel.
