EGR, Evap and Vacuum Problems
« on: July 15, 2007, 03:42:29 AM »

I have a lot of questions about EGR, Evap and Vacuum since I turbo'd the engine.  I'm running about 10 lbs of boost.  Ever since I hooked up the vacuum tubes for EGR and Evap, I'm getting a whole bunch of codes.  Cruise control doesn't work.  I'm just gonna take that whole system out.  I put an EGR "Missing Link" on and it still hasn't fixed anything.  I'm thinking about totally removing all of the EGR, Evap and non-essential vacuum tubes.  But if I do, I'll get fault codes for them not being there.
Does anyone know of resistor (jumpers) I can put into the cannon plugs to trick the PCM in thinking that system is there?
If I totally remove that stuff, will it fix my problem?
Are there PCM mods to redo the computer so that stuff isn't in there?
Should I use a piggy-back or a stand alone?
Will a piggy-back or stand alone be able to correct EGR or Evap problems?
If there's anyone that knows a lot about this please feel free to email me or call me 775-217-4365.  Please leave a message if I'm not there.  Thanks in advance.

First off, block the egr clean off.  You will lose boost through it.

There is nothing you can do for the pcm, unfortunately.

I should just block off the EGR and the EVAP.  Will the engine run boosted but I'll have a light, right?  I can live with the light.  I checked the manuals and none of the vacuum systems (as I see) run anything essential.

Alright, well blocking of the EGR will do no harm, I've pulled all mine.  You will get a light.  You can pull the bulb if you like (just remember that you can do the CEL tests then).  You can run boost with the Missing link in there.  AEM makes a great stand alone for our car.  And it doesn't give a crap about EVAP or EGR systems.  There is a resistor you can put in to make the EGR system think it's running properly, but I don't know what size it is.  Check with Bad Venge or Nykon they MIGHT know.  As for you cruise control I"m not sure why it's not working with out a better description of the issues you're having.

Mod List.  Um WAY too many to fit on here.  But the engine can handle about 800HP
