Edge Ez level 5 problem ????

[EHosmer]

Is this coincidence or is it because I used the secret level everyone is talking about. I purchase an edge ez and installed it on my ram, right away I set to level 4 and was pleased with the new found power. Then I read the posts about the secret level five and moved my jumper to this new level, whew !!! this dualie was even quicker now. Where are those Fords ? A few days of driving it like I stole it and I noticed diesel fuel on my tailgate, a little further investigation and I realized that the whole undercarriage of my truck was dripping in diesel, oh no. I unhooked the edge and took it to my dealer where they inspected and said when I changed the fuel filter I didn't get the top on tight. Well when I left I dogged it pretty hard going home and when I got there and inspected the undercarriage it was wet with diesel again. Now I called edge and the tech there told me that no one has had any problems running on this level, however they don't advertise or reccomend using on this level but no one has had a problem? I do remember reading a post about over taxing the spring? and the fuel recirculation line. It appears as we speak that DC is going to do the repair under warranty, They now think that the fuel is coming from the fuel recirculation line which is behind the head and above the bell housing (a bear to get to. ) Nothing has been mentioned by them about modifications/pressure boxes etc. My dilemma is when I get my truck back hopefully next wed. should I try level 5 again or settle for less power like level 4 . Please advise as I value the knowledge that I have read in countless hours of pouring over posts. I a new member so try not to be too hard on me. Sorry this is soooo long. Thanks Eric

Ive has my edge for about 3 weeks. . No problems like this.



Come on guys help him out... anyone else have a problem like this?



I know this is the first ive heard of anything like this...



Nick



BTW: welcome

I ran my Edge on level 5 for 2 days, HARD. Couldn't really tell any difference from level 4 but I did set 3 new codes, one being over boost. Running now back on level 4.



Hope this helps -John

10k on level 5 with no problems... Don't know if it would happen again or not. . maybe something just wasn't right and now it's fixed on warrenty

 

[EHosmer]

I really could tell a big difference between level 4 & 5 engine pyro went from 1200* to 1350* boost went to 30# from 27-28#. I didn't have a problem with codes.





Thanks for your reply, Eric

Are you referring to the high pressure pop off valve? At least I think that was what it was called. It releases the pressure when it gets to high

 

[EHosmer]

Clayton-- Im really anxious about this, hopefully it was something that wasn't just right and the additional fuel and pressure created the leak. Thanks for your reply--------Eric

I think I've had my ez since January and haven't had any leaking problems. I ran it on level 3 until last saturday when I received my new exhaust and felt comfortable running it on level 4, now that I have it breathing better. IMO, I wouldn't run it on 5 just because Edge doesn't recommend it. So that in itself is enough for me. But then again I'm a little on the prudent side and is the main reason I went with Edge EZ. From all the posts I read here their product seemed to be the most reliable or atleast caused the least amount of side effects or problems.

I agree with KKlepfer, I just adjusted my EZ back down to level 4. I feel better about the reliability of all parts involved if I keep the settings at what Edge feels are safe.



I will on occasion jack it up to level 5 but it will be rare. This truck running without the EZ has more pulling power than my 99 did with an EZ. It's not alot more but it definitely is more .

 

[EHosmer]

lmills-----again let me temper my reply with a dose of ignorance; This is my first diesel, as I understand the mechanical workings the fuel that the engine doesn't use is recirculated back to who knows where evidently via this fuel recirculating line, with more pressure comes more fuel to the point of overtaxing the recirculating line to the point it blows a seal? breaks? cracks? one thing is for sure in this case it really==== leaks. and thats where I 'm at now. Obviouslly I can't ask too many questions at dealership or they might become suspicious.

that's for sure Anyway there is supposedly a high pressure pop off valve thats designed to save the commom rail from excessive pressures. When it releases the extra pressure is blown off. I am not sure as to where it goes though.

 

[lmills]

BTW I believe the 03-04's are the same as the older 24 valves. The return line is dumped into the tank.

 

[BRayls]

only leak I had was while on level 4 with an injector line and I just snugged it up. level 5 over 5000 miles now,and loving it.

 

[DLeno]

If your high pressure safety pop-off goes, you have a blown rail, a dead engine, and a dealer repair. its a one-time thing.



something else must be going on. There was one guy a while back that had injector seals leak with the EZ on the highest levels.



I haven't seen or heard of any problem like this one. Seems to me if the low pressure return side is leaking, then its not the EZ's fault (only coincidence). I'd be interested in the conclusion to this story though

Not necessarily true. While some will pop and stay open, not all will. We have seen them pop and reclose... however, once they have popped, the pop pressure point is reduced as the spring sacks out. The next time won't take near the pressure as the first.

 

[EHosmer]

There wasn't any hesitation, sputter or check engine light , or any codes thrown, there was only a deposit of diesel on the undercarriage and this wouldn't happen unless you floored it through the gears. Once the edge was removed it would still drip diesel when you ran it hard. Where is the location of the pop-off valve ?

 

[DLeno]

sounds good kieth. I guess now all the pressure box guys can sleep better at night knowning that that if pop goes the weasle, it will either require dealer service or it will pop easier the next time . But seriously thats an interesting detail I wasn't aware of.



I still dont think this dripping fuel thing is the fault of the EZ. You might have to steam clean the engine and under carriage and try and locate the leak source.



I dont' know where the pop-off is, but something tells me this is a high pressure side problem. I say that only because I expect pressure on the low side to be under less pressure and returning less fuel to the tank while during WOT but the high side will be delivering more fuel and under higher pressure under WOT. I'd look for leaks around the rail and injectors, or perhaps the pump itself, high pressure lines, etc. how come the dealer isn't doing this work?

I just ran my 03 SO on level 5 for a few quick blasts down a country road and I found a big difference over level 4. For kicks I set the cruise @ 55 mph and noted the EGT of 450* (post turbo, I know, I'm moving it soon!) then did a run at WOT to 105mph and 800*. I then cam home and moved the jumper to the level two position (what did I do with the second jumper needed for level 1... . ) and did the sam run. The results were 425* @ 55 mph and 700* @ WOT and 100mph. I was expecting a larger difference. Could it be the post Turbo (3" down the pipe) location of the porbe? Other than that no error codes or dripping fuel on the truck.

Fuel Leak on Level 5

I agree with DLeno about it being a high pressure side. I looked inot it and when the valve opens it dumps the extra fuel into the return circuit back to the tank. Here is is in Chryslers words: DESCRIPTION

The fuel pressure limiting valve is located on the top of the fuel rail

OPERATION

Fuel pressure at the fuel rail is monitored by the fuel rail pressure sensor. If fuel pressure becomes excessive, the pressure limiting valve opens and vents excess pressure into the fuel drain circuit.

I can also get the diagram if your interested, it's just a fitting on top the manifold with a bonjo bolt.



Hope that helps!

Dang thats got to be a lot of pressurized fuel spilling back into the tank.
