Using resistor for egr delete

[tjl006]

Anyone have an opinion on using a resitor to fool the computer into thinking the egr is functional? Even with the egr deleted in the tune the computer will always have a p1000 code or at least the emissions systems will not be ready when its time for inspection. Does the egr funtioning or not funtioning affect the tune in any way?

I don't think it will work.

I have a question, why would someone delete the EGR anyway. The EGR doesn't function at WOT anyway

With the eaton swap the egr is a tight fit and you would need to modify the tube from the exhaust to make it work.

As well as mods to the wiper cowl for it to fit.

Thats what i meant by tight fit. any resons why you belive the resitor wont work? I read that some mustang guys were doing this.

The computer knows the EGR is working when it senses actual flow of exhaust gas back into the intake tract. It knows to expect flow when it sends a signal to open the EGR valve. You'd need to figure out what sort of signal the flow sensor produces, and tie that to the signal going to the EGR valve in order to make the computer think exhaust gasses are recirculating.

Even if you could do that, you'd probably have trouble passing an emissions test. EGR keeps the combustion temperature down, which helps to prevent the creation of oxides of nitrogen. If your local test checks for oxides of nitrogen, which they probably do, you may be sol.

test is just obd2 not sniffer

I was under the impression that the EGR system checked for a reading with the EGR valve closed and a different reading with it open. If the system doesn't have that much intelligence built in, then a resistor might work.

I really dont know how inteligent it is to be honest with you. Isnt the map sensor function built into the egr on these cars?
If the egr simply functions as being opened and closed then I belive a resistor should work.

Actually there are 3 functions built into the EGR valve. The EGR valve itself, the EGR sensor, and the MAP sensor. The Cobra and most other Ford cars & trucks have a separate EGR sensor. DPFE, DFPE, something like that. Somebody posted an interesting EGR thread a little while back.

My comments were based on how my 1994 2V 4.6 worked, for which I had to replace the flow sensor. But, that was OBD1. And nearly a decade before the MM.
Sorry, didn't mean to mislead.

[tjl006]

No problem man. Where all just trying to figure out what we can and cant do to these cars.

I believe this thread has some good info: http://www.mercurymarauder.net/forums/showthread.php?t=59569

Turn it off in the f'n tune and don't worry about it. You don't want the engine thinkin its there then using A/F timing charts based on false input.

Kinda right but kinda wrong.

You want the emissions test facility to be able to see the sensor is active, whether or not it really is.

I just deleted everything emissions related on the Cobra and I too will be digging deep into wiring charts and voltage values to try and fool the pcm.

My man:D Also havnt forgot about calling u. i am getting a new boost a pump instead of using the lethal Knockoff. I got a feeling the code is because of the old boost a pump, its a different wiring setup then the kb bap.

did you guys ever figure the egr stuff out?

[burt ragio]

If only the egr bit could get worked out for the eaton conversions. Some state inspections are just plain tough.
