Edge Evolution

[mohle]

Anyone know what the Edge Evolution (not CS/CTS) changes in the ECM when set on economy? More specifically does it change the EGR programming?

I would also like to know this. I'm under the basic assumption that all programmers disable the EGR valve to some degree, hence the gain in fuel economy (as long as your right foot allows).

I've got the Evolution but I'm only using it as set of gauges. Never programmed it. A friend of mine has it and under economy setting he sees the occasional black smoke when about 1/2 to 3/4 throttle. Leads me to believe that it does bypass the EGR, but wondering if anyone can confirm this.

The edge isnt going to by pass the EGR. the black smoke is from more fuel being added to the truck, The most economical tune is the highest tune if you can keep your foot out of it. When the truck has more hp it takes less to get it going giving it more MPG.

The edge will not remove the egr from the tuning. You will have to get custom tunes to do that.

I have the Edge Evolution and i would only recommend using the Tow Tune. The Hotter Tune has significant timing so you will want to have Studs and an EGR delete. I have been very happy with the Evolution which program shift firmness. Their customer support has been great.

Not even interested in the hot tune. The ones of interest are the tow and economy tunes. The reason I'm asking about the EGR is because of the black smoke and it would make sense to limit if not down right turn off EGR operation.

Under WOT and most acceleration, the valve is over 90% closed anyways. At cruising speed the valve cycles through various percentages of open to lower in cylinder temps. Yes there is power loss with the valve open, but at cruising speed it is negligible. And if you run the performance tune, you will get better mileage than any economy tune. If you look through the manual, most canned tuners even tell you that with conservative driving, it will give you better mileage.

What I'm looking for is to reduce the deposits in the EGR system. I'm doing the regular EGR valve cleaning, but that's just the valve. Who knows what the cooler looks like. Hence I'm looking for ways to reduce EGR operation while remaining relatively stock. I don't want a delete kit as I believe there are other headaches that may arise from it.

If that's what you're trying to do, get a second EGR valve. With the Engine off, key oof, unplug the egr valve and plug in the second one. Use some zipties to attach the second valve to the intake elbow.
