Doesn't fix the fuel pressure dropping and that's the real problem...that is a bandaid attempt that many people opt for to mask or when some aren't aware of the underlying pressure problem

I have read some data indicating E-85 has a higher viscosity than straight gas which translates into friction and backpressure.

If this can relieve some stess on the pump, I'm all for it.

Livernois has also alluded to the excessive sulfer in US gas slowing down the fuel system as well, and I think it is part of the puzzle.

Looks like we may all get a FRP boost shortly...

"The proposed standards will reduce gasoline sulfur levels by more than 60 percent – down to 10 parts per million (ppm) in 2017"

Have to say, I find fueling limitations significantly less attributable to emission based qualities than to mechanical deficiencies.
Already, sulfur caps are fairly low. And it's like alot of the other mandates, real values are generally maintained low, in order to keep a nice cushion from mandated caps. For example, sulfur in ULSD stays considerably lower than the standard 15 ppm cap. I believe LSD has now been fully phased out and transitioned to ULSD, 15 ppm or less.

Gasoline is similar. I've never seen more than 30 ppm in the RFG around here. Though, our PQI standards don't require regular sulfur analysis in any but diesel fuel.

Also, if you want to maintain high lubricity in gas, always buy premium branded. Shell, for example, has the highest treat rate of their additive in their VPower. Additive, in addition to detergent priperties, lubricates and offers anti-gumming agents and other qualities as well. Seeing as ethanol in fuel is pure alcohol, with a denaturant and no additive, I'm not sure how it offers much lubricity.

I always run shell 93 as my base fuel. But as the E goes up, frp gets harder to maintain so there are physical properties of the corn that cause the slowdown.

Fomo that's not the reason...as ethanol concentration goes up so does the fuel demand...you need more fuel to maintain your commanded lambda...that's why fuel economy suffers on e85...stoich for e85 is very low...9 something in afr I think...

It's why if your fuel system was at the edge of capacity on gas you have no prayer of running e85

I understand demand goes up. But as the E goes up pump output decreases. So double jeopardy. You can see this behavior in logs, min and max fuel pressure.

It is easier to pump 93 through the system than the corn.

What are u logging to see pump output?
Commanded pump pressure
Actual pump pressure
furl rail pressure

AJP turbo

I'd have to see it....I would say the pump pressure is also related to the high fuel demand....What is the pump duty cycle?

When fuel demand is high the pressure will fall everywhere

Don't know on the duty cycle, I will add it to the parameters.

So basically what you are saying is it is draining the rail?

One thing is for sure, I will let the Mustang and ST guys find out the results before I drop a grand on injectors.
