EGR Removal Question

[tsunari]

Haven't found many threads relating to this . . . I'm about to put my engine back together and I'm going to ditch the EGR. Will I have to worry about CEL's ( I have a '97 GST)? Or do I just have to block off all of the proper vacuum lines and put on a blocking plate? No other sensors to trick/disable?

Most threads I've read deal with the 1Gs

first do this....

then make a block of plate for the egr valve with some sheet metal

need i do anything to the temp sensor? the one on top of the TB that makes sure the EGR is working properly?

 

[greeneclipse]

no....you dont need to mess with that.

Moved to General Discussion.


The CEL mainly comes on if the electrical connectors are unplugged.

so in the 2g you should be fine following taboo?? no cel

yeah on my car I didnt even have the egr hooked up all since the Magnus intake cant even use it...and I got no CEL eva

The ECU will check for a change in manifold pressure while the EGR valve is open after the OBDII drive cycle completes.The drive cycle is:

1. Decelerate (coast down) to 20 mph without braking or depressing the clutch.
2. Accelerate back to 55 to 60 mph at ¾ throttle.
3. Hold at a steady speed of 55 to 60 mph for five minutes.

So you may not get it right away, but you will eventually get a CEL for low EGR flow and EVAP leak.OBDII is very sophisticated, it not only checks for proper operation of the sensors/actuators, but also for blockages, leaks, etc.Leaving the electrical connectors plugged in will not help, you will eventually get the CEL.

Why you want to remove the EGR?

Well i wanted to try and get my intake temps as cool as possible . . . not to mention keep my intake manifold clean, but after doing more research, I've concluded that a properly operating EGR is more beneficial than just ripping it out. So I cleaned mine up and am keeping it.

 

[FourG63 97GST]

cool, cuz I was looking into also like a week ago,
and it seems its only open at low/partial throttle.
and closed at WOT, so exhaust wont be goin into the intake to cause any increase in intake temp.

 

[tsunari]

Yeah, it is supposed to close at WOT. So HP gains really wont be seen all that much. However, I'm sure if the EGR is stuck open/closed, it could cause problems.

this thread will answer any questions you have about removing the EGR im pretty sure.http://www.dsmtuners.com/forums/showthread.php?s=&threadid=111373
i say do it if your in a position where you can get to it easy and dont have to take stuff out just to block it off.
