Video About E85 And Contamination

[r32-25t]

Saw this today thought it was interesting and thought I'd share it

Ok, so, for the dummies like me ..

Is he saying that using non E85 fuel will cause contamination which will in turn cause your tune to not be as effective?

[r32-25t]

He is saying the left over petrol will cause it to read a lower ethanol content which will make the sensor wind back the tune (reduce timing) even though the contamination is so little it won't effect the knock resistance of the e85

Also "If you get water in your system, your car is gonna think that water is SUPER ETHANOL" and act accordingly... when it isn't.

[Robzilla32]

Wasn't it even calling into question the validity of "flex" altogether?

[Hadouken]

So he is against e85....... And flex sensors.......

[r32-25t]

Sounds like it

[Hadouken]

I still like it. Even with my water

[Robzilla32]

So SUPER ETHANOL is even more super than regular ethanol.....well I'm in!

Don't put the garden hose in the full hole and you should be sweet.

[Robzilla32]

Don't use garden hose. Got it. Phew, that saved me some embarrassing conversations...

Can't be bothered finding the paper, but basically for port injected engines of our vintage there is no additional knock benefit past E40. So really your timing map should alter from E0 to E40 and your fuel map should alter from E0 to E100. I bet the Wolf (like most others on the market, to be fair) isn't smart enough to do this. So rather than make a video about it they could improve their ECU to solve the problem they are talking about.

OTOH, because the ignition map is still scaled to E100 same as the fuel map you lose out on a little bit of ignition timing if you are swapping fuels. Big deal. You're in it for the convenience, right? You still get it, right? Who cares!! The people who are in it for the last 1% of performance are running full E85 conversion, not flex.
