hello

I'm off on an EGR EGR ONLINE tonight on my vehicle and when I start it, it smokes a lot and do not take RPM

have you any idea?? please

ps: not with the original problem file, it works well

Hi,
i have checked your uploaded and modified file.

You have to detach vacuum pipe from the egr valve (blak around 5mm thin vacuum pipe).

The proper procedure is also to blank the egr at least on inlet like shown on picture.

Some checksum blocks in your file are not recognised, can you post your original here once again to be sure that file is ok.

thank you for your prompt reply

here is the original file, and FAP off about 150HP, what do you think?

haha I did EXACTLY the same with my brothers Alfa!

As ecuedit says, if you look at the EGR valve on the exhaust manifold you will see a rubber vacuum pipe coming into it. If you follow this pipe you will come to a little electrical valve, again with two vacuum pipes (one going into the EGR valve itself and the other going to the vacuum source).

You need to:
1: Disconnect the electrical connection to the EGR electrical valve (EV).
2: Disconnect the vacuum hose that feeds vacuum to the EGR electrical valve and block off the hose you just disconnected (with a bolt + a dab of silicone sealant does the trick nicely). This is to make sure you do not have any vacuum leak :)

Otherwise, as the ECU no longer controls the EGR electrical valve, it just holds it open all the time. The car will run like crap.

In the long run, you really need to remove the EGR valve from the exhaust manifold and the piping from that to the inlet. Then you need two decent thick blanking plates (one to go on the exhaust manifold where EGR valve was, and another to go on inlet manifold where EGR pipe work was). Make sure you get new metal gaskets for this too... Just doing the two steps above will get your car running nicely for now with no-egr :)

Could you attach the file to the post by using "upload attachment" ? I am struggling a bit with that web-link

Hi, you are welcome.

Your file that you posted is different that the file that was posted for EGR off, it has 6 changes.
Here is EGR OFF for the original that you posted here.

cheers

I do not understand because my 607 is 2004 and if I unplugged or mouth anything without making changes in the computer it gets degraded mode

I thank you now test

Now it won't be "degraded" because it is switched off as it has to be...

Yep... you have to make the change both mechanically and also in the computer programming (that ecuedit did)
