Have any of you northerners had the display screen go blank in very cold weather?I'm ordering the Edge before the price goes up but if it doesn't like cold weather and needs frequent unplugging and resetting when it's cold it may be a seasonal mod up here in the northeast.

 

I have not heard of that issue, but I do know that my old Banks 6-gun (7.3L Powerstroke) does that until the interior temps come up. I would expect the display to get a bit slow in extreme cold...being that it is liquid crystal....but I would think it would still function. I would also think that the contrast may need tweaked as the temps go from -10F to +95F.

 

from what i saw on another post was it still worked but you were not able to view the gauges. When the temp was 20 or lower is when you had the problem.

 

I have a question for DPP! We've got a 2006 F150, with the 5.4L FFV (flex fuel) motor. We've been running it exclusively on E85 (105 octane). We're considering an Edge Evolution for the mileage and transmission life benefits.

First, is the Edge compatible with the FFV truck? Second, we could pretty much set it on level three and leave it there with E85, right? Third, have you had any customers with the FFV truck, and how did they like it running the Edge with E85, both mileage and power wise?

Thanks in advance!

 

I really can't tell you. Out of nearly 1000 units sold I would imagine someone had a FFV. I have not heard anything negative about it, I've never heard anything at all about it. I can call Edge monday for you, and see what they know.

 

yes, i would be interested to know myself because i just ordered mine and i'll run E85 at times also...

105 octane????? is that what E85 is....105 Octane??

 

Yep, 105 octane, and that's the winter blend. Summer blend is higher, how much I'm not sure of though. The performance fuel of the future!

I think Edge would get a jump on everyone else if they made performace and mileage settings specifically for E85.

Oh and DPP, any information from Edge will be greatly appreciated!

 

wow, thats very interesting....you would think at the min of 105 octane you could get more preformance than with prem. gas...

 

Octane has nothing to do with performance. The octane rating is based on the fuels ability to detonate. The higher the octane the harder it is to light. High compression engines require high octane fuels to prevent ignition knock which is nothing more than the fuel igniting from compression before it is supposed to. E-85 is higher octane and can be run in higher compression engines then gas, however it is lower in BTUs, so it takes more of it to make the same amount of power as gasoline.
Not sure, but the edge should still work as your PCM is taking readings from many sensors and adjusting the engine parameters accordingly, in other words if the engine is running the PCM doesn't really know whats feeding it, it just makes adjustments till it thinks the engine is giving optimum performance.

 

I would have to agree with you cwc, but none the less. I like to hear from the horses mouth. I won't make any claims for Edge lol.

 

At the risk of turning this into another ethanol thread, of which there are plenty in the alternative fuels forum:

Higher octane lets you adjust the engine for maximum performance if the current octane was inadequate for the engine design (compression ratio, combustion chamber dynamics, etc). For instance, you can add timing without pinging (much like the Edge probably does). Now if this lets you add usable timing to the engine at highway cruise, where the engine would have pinged with 87 octane, your mileage will go up. With E85, this would cause the mileage decrease to be less than expected were it based on only the BTU value.

E85 is lower in BTU's, but if you run both at stoichiometric, there are slightly more BTU's released with E85. Therefore you use more fuel, but you get more power. E85 also cools the intake charge more than gasoline, pulling more air into the cylinders as well.

So as you can see, high compression engines would be ideal for E85, but current engines have a lot to gain as well, especially if they were detuned from the factory for 87 octane.

Thus my interest in the Edge.

 

very interesting....so, i could keep bumping the timing up and possibly gain more power than gas and end up with around the same mpg also....

i'll have to mess with it a lot when i get it this week and i'll post my findings...

i would also like to hear what edge has to say about it cause i'm sure they discussed it...

 

Hey guys, does anyone know if Edge is working on a solution for turning off the Tire Pressure Monitoring System? I emailed them but figured I won't get a response until Monday.

 

I have not heard anything about that one. Make sure to post the reply when you hear back from Edge....there may well be others that would be interested in your sharing of that particular reply.

 

You sent us an email about that this wekend. Did you also email Edge?
