I got the new edge EZ, I installed as directions say along with boost elbow. When I started the truck, the engine light came on and stayed on. When I mashed the pedal, off I go and the boost rises rapidly up to the high 20s. Then...Within a second or so after I've mashed the pedal, it stumbles hard and the boost drops simultaneously with the stumble. If I continue to hold the pedal down, it will still accelerate but very slowly. I called edge and they said to unhook and hook it back up stock and try it. I did so and the engine light still stays on and the stumble is still there. I tried the EZ in the first and third positions and the results were the same.

Has anyone had this happen? Is it more likely a connection or is it boost elbow related? The guy at edge said I could pull the batt cables off overnight and it should clear any codes and the engine light should go out. Is this true, and does it take overnight or will an hour do the same thing? This truck is a 2004 HO made in Sept.
Thanks!

 

Hey Todd! Sounds like your EZ failed to override your ECM, your computer detected an over-boost condition and began defueling, hence the stumble. The software in the EZ is supposed to "fool" your on-board computer to allow the higher boost condition. I would think that disconnecting BOTH ground cables from your batteries for an hour or so should do the trick. I believe that your engine light may go out, but the code will still be stored in your ECM. If you take the EZ off, be sure to take off the boost elbow, as you will go right back into the defueling situation if you mash the go pedal again.

It sounds like a bad EZ (pretty rare) or your connections are faulty for some reason. If you have an EZ for the wrong year truck, that could cause the problem also. Some of the other guys may have some other ideas also. Hope that this helps some.

I have two (2) bad drag box's right now and hopefully a "good" third one on the way right now...

I have already had one traded out... So this makes three bad Edge box's.

Maybe it is rare for the EZ but I would be hard to convince it is rare with the EDGE product at the moment.

They do have excellent Customer Service...

I will try not to let all this cloud my judgement on which box I go with for my 04 but I am getting somewhat leary.

I was just searching the forums and found this thread.........

https://www.dieseltruckresource.com/...ighlight=codes

After reading the first post, I immediately knew what I did wrong. I forgot to hook the wires back up on the breather tube. I swithed the key on 3 times and the codes 73 and 107 came up, the same codes the guy in the thread above got. The only difference is... my engine light is still on after viewing the codes. I pulled the cables and turned the key to the on position, I'll hook them back up in a few minutes and see what happens.

I'm guessing that there is no problem with the EZ/boost elbow and that the only problem was my stupidity in not hooking the wires back up.

Did I do correct by turning the key on while the cables are unhooked or does it even make a difference.

I sincerely appreciate the quick responses and all the help you have given me!
Thanks,
Todd

 

Yeah, Todd, you should have the key on after disconnecting the ground cables. That drains any capacitors of residual juice so that everything goes "dead." I'm glad that you were able to locate the problem.

JCL, I'm sorry about your problems! Maybe Edge has (had) a glitch in the new boxes for the third gens. Hopefully, third time's charm

Todd, be sure to post and let us know how you make out.

I got a question for ya. When disconnecting the power to clear the codes, will you loose other changes that you have made to your ECM? For instance, my dealer changed the tire revolutions per mile to match the 315s I'm running. Since these numbers are not a pre-programmed option and had to be manually typed in the appropriate spot, will resetting the ECM erase this change? Just curious for future reference.

 

AK RAM:

I don't know for sure, but I would think that those changes made by the dealer would not be lost with a battery disconnect. Otherwise, every time you had to disconnect power for any service, you would lose those changes. I have had a dealer reflash on my ECM, and those settings are not lost. Best bet would be to check with the people who did the work, I guess.

Well.... I hooked the breather tube wires up and the cables and started it up with the edge in position 3. Everything worked great but the engine light was still on. Cycled the key on a bunch of times and the light went out. I can still get the codes to come up though.
I went ahead and put the EZ on position 4 and left it. I don't see much reason to use the first three settings unless they get better milage. Does anyone know if position 4 gets worse milage than stock?
Thanks,
Todd

 

I think you will see a 2 mpg decrease no matter which setting you use. My overhead display shows 2 mpg better than before when in fact I am getting 2 mpg worse than before the box (hwy). When I initially hooked it up I had it set on level 1 and the mileage was 2 mpg less than before. I haven't checked it since going to level 4 but now I have the 315's so I have to get the speedo re-calibrated before I can check it again.

This is what I have found with my truck but these trucks can be strange with one person having much different results from another with the same modifications...

Enjoy the box.

 

I know that my '99 is different than your 3rd gens., but I get about the same mileage with the EZ when solo, and about 1.5 mpg better when I'm towing. My experience is that those who are getting a decrease in mileage tend to use the extra horsepower quite frequently. I really try to watch the go pedal, with admitedly mixed results. But I've checked numerous times (actual miles/actual gallons, no computer) and my numbers are accurate.

 

I gained about 1 mpg empty and 2-4 pulling. Over head computer is off by around 4 mpg.

I had a similar problem with my Bully Dog box.
