I have been looking at this for a while now and am getting tired of it, seems like i might have a little power loss but not much if any, I recall a thread that i saw a while back, about using a potentiometer, or something like that on one of the many sensors fool the computer to think that it has been cleared, anyone know what i am talking about, any help would be appreciated?:thumbsup

Did you take the DPF off and not put a fooler box in? If so that is your problem. What you are talking about only works on the Cab & Chassis models. You need to get a hold of H&S or BADP and get a fooler box. You have lost power because your truck has derated.

It will work on the regular trucks to atleast it has for the ones that i know of that tried it the voltages are just different

I have all of the exhaust on at this time but, the cat and the dpf have been hollowed out. I put about 740 miles on the truck with the exhaust gutted, before the cel ever came on, dont know why it took so long, but it did! I had read somewhere on here that you could use a potentiometer, or whatever it is, to apply a certain voltage to the sensors to fool the ecm to think everything was o.k. did not know that only worked on c&c models must not have paid attention to that part, but i would think that if you knew what voltages that the sensors sent back to the computer when everything was good that you could rig something up to do the same thing!

this is your problem. Awile back, i was stupid enough to have someone do the same thing. I had about 100 miles on her before she started sputterin. Your truck WILL GO INTO limp mode. even though it cant be full, the engine or computer or whatever thinks it is. im pretty sure you can also burn your engine up as well.

How can it go almost 1,000 miles with no lights, and then come on, the computer system on this truck must be as slow as my dealership's service department!!!:lol3:

 

[jon111]

i really dont know. but what i do know is your truck will be effed if you dont fix it soon. limp mode is not a fun time.the only way dealer will cover it is if you were careful and didnt make any scratches inside it when hollowing it out.

Your ecm runs in cycles, it checks everything periodically. You will need to replace it back to factory condition if you can but if you can't...:$:

You will need a fooler box

 

[ciamcoop]

You need to find someone's exhaust system that they removed, borrow it, put it back on your truck and take it to dealer. They have to reset the comuter. Then you can get the fooler box, return the exhaust to the rightful owner and then put your custom system back on.

I don't know how close they check, but I thought the dpf was stamped with a number that matched it to the truck it came with.

 

[jon111]

they check realllllll close. when i had my "situation", they said that only certain bolts were shiny as in they were recently removed. i was like wtf, oh shiiii. lol. but somehow they covered it. prolly helps that my family and i are real close with the owners. a new one costs like 8K i think.

:$:Turbo back to tailpipe 2008 mega like mine $3,200 already checked!:$:

Who puts out the best fooler box? And what exactly does it plug into?

Someone posted info on how to build your own fooler box a few months ago. The information is in the 6.7 forum somewhere. You may have to do a lot of reading to find it, but it is there. I did a few searches and could not find it...you will learn lots while you look for this info at least.

Who ever built this homemade fooler box, can you give us all an update on how it is doing?

Thanks....

Both BADP and H&S have boxes out there that work fine. BADP is supposed to have a code free one releasing any day now. You cant go wrong with either one.

 

[Daburt]

For what they're sellin for they should be code free!!

 

[Lone Star]

1K for the BADP "Code Free" installed at BADP shop. IMO thats kind of steep.

Thanks bohica48...good to see a newbie that knows how to use the search function! Welcome to the forum!
That is one of the threads that explains a bit on how you can build your own fooler box. There is another one that went into more detail, but you should be able to make one given the info posted in the H&S fooler box thread.
