egr delete???

[STRKTHS73]

alright so two questions a friend of mine has an rcd egr delete in his 06 6.0 his check engine light comes on like normal but his question is is there anyway to get the check engine light to go off without an sct of programmer so it doesnt screw with the fan clutch also i have an sct and im getting a delete soon on my 06 how do it do it with an sct programmer thanks for the help guys

For your friend: Yours Sh*t out of luck.. only way to get the CEL to go away is a SCT programmer with the either tune built in or an older sct x2/ x3 with custom tune and EGR disabled. The egr is designed to detect airflow and that is why his keeps tripping it. the computer isnt sensing any air flow in the "cooler"... since he deleted it u can mimmick that best bet get a used tuner and follow above steps.

For you: SCT livewires have the option of turning EGR "off" and using the canned tunes.. or you can buy a custom tune for older sct's that has it turned off. Hope that helps!

EGR deletes... while ur in there deleting the egr replace oil cooler intake gaskets if u cannot reuse ( dont recommend reusing those) and would be a GREAT time to swap over from ford gold to ELC coolant.. just my 2 cents!

No, you can turn it off with tuners other than the SCT

But yes, you do need a tuner of some kind to turn it off.

Hmm.... I wonder if you removed the EGR Valve, installed a blockoff plate, and mounted it somewhere so that the fan would blow air on it, if that would trick it into sensing 'flow' XD Anyone want to try it?

yeah i figured there was no way of tricking it sucks to be him lol as for me iv already got the studs oil cooler egr delete all gaskets stc fitting banjo bolts oil drain an feed lines ficm and coolant filter sitting in a box in my garage an i already swapped to cat elc ec1 coolant at 30k miles ones my hgs go ill be on my way to bullet proof but thanks for the help guys im sure my buddy will b more than ticked off to hear he cant trick the dang sensor

The EGR valve itself doesn't detect air flow, the valve opens and closes based on exhaust back pressure readings and intake manifold pressure (boost) readings that are sent and controlled by the PCM.

Lilpooh,

What happens (computer wise) when you delete the EGR cooler but keep the EGR Valve in and connected? Doesnt the computer read the lack of flow? Does that cause a problem?

Try putting the EGR valve back in

The EGR valve don't read exhaust flow/temp. It gets it's commands to open/close from the PCM. The PCM monitors exhaust back pressure (EBP), and intake manifold psi (boost) to control the position of the valve. The EBP sensor, EGR valve and VGT is used to determine exhaust flow thru the EGR cooler.

I'm not a tech, but I think this is how it works. If I'm wrong, somebody correct me.

When you put on a EGR delete, and leave the valve plugged in, the PCM still gets it's signal from the valve. The VGT allows more flow of exhaust gases by increasing the EBP, the EBP must be higher than boost psi. When the PCM sees that the boost is higher than EBP, it turns on the CEL and you get a code.

I'm pretty sure the MAF is almost entirely responsible for detecting EGR flow. even if you could trick the maf so many trucks are different one fix might not work for the rest
