just did a test drive with my 04 6 liter, I did the stealth egr delete. I had a P0400 error code any concern?


Thanks for the help

 

Several tuners on the market that can clear it, and keep it clear. I think you can do it with the torque pro app as well.

 

I bought the Edge Products Insight CTS, from Ed at ficm repair so hopefully that will keep it clear..


Thanks

 

Insight is a gauge and won't clear it.

 

InSight is also a code reader and is able to clear codes.

 

The code will recur. You can delete the stored code as many times as you want, but it takes a tuner to disable the coding otherwise it will just keep coming back on until you change the programming. I can turn off the CEL temporarily by deleting codes with my Insight, but it comes back until I use the SCT 3015 to disable the EGR valve.

 

Gotcha..my misunderstanding. So it will clear codes, but not permenantly.

 

Yes and no, it will clear codes but will not change the programming, without changing the programming the codes will continue to reoccur every time the truck computer looks for the EGR status. By using a programmer you can disable the EGR which will remove it from the computers checks, therefore no more EGR codes.

 

Thanks for the info, on another note. Is there a way to "easily" disable my '04 from starting...theft deterrent.

 

Pull the FICM relay. It won't start without it.

 

Another Question..is it under the hood or with the fuse panel? Thanks again

 

Under hood #304 IDM relay. Check your owners manual. Or search here for a pic.

 

Ok Thanks again,,I just noticed a post from you,,WOW stock head bolts..I'm impressed.....any idea with pressure your developing in your coolant system, when towing and climbing on grades?? ? I just did gaskets and studs in my 6 liter.

 

If you want inside the truck pull fuse f2 22.

 

Exact pressures I don't know. I never had excessive pressures or venting from the degas. Heads were done under warranty by Ford when it had I think 24,000 miles around 2007. I have on it 155,000 miles plus.
I'll warn again watch the temps and boost. High boost you're looking for trouble in my opinion based on my experiences.
