How to disable EGR for 147 1.9 JTD 8v?

[dusan147]

I blocked (by thin plate) EGR in my Alfa 147 1.9 JTD 8v engine. But I have error about EGR function, occasionally. Error appears only in diagnostic procedure (by FiatECUScan) but doesn't in boardcomputer screen...
What is the proper way to "disconnect" EGR by software i.e. in map?

in software

I know that, but I need details (address in map or something similar)...

Put the file that you can help

Here you have both maps,adress for ecm is in under side from page.

Go to 'phase of injection' and set all values to 183 to disable EGR

Good luck.

If any question,just ask.

Thank you rsibiza - could you tell me what software you use for this: ECM?

[ipejasinovic]

Yes, it's ECM2001. You can find it here: http://www.digital-kaos.co.uk/forums...lection-65195/

thank you ipejasinovic, I go there, now...
Well, my friends are overjoyed about your help about idle speed...

I looked some maps and saw value of 183 (in high power and high RPM area) and 194 (for lower power and RPM). What is the reason?

Man, those are just "Mass of Air" expected values.
Keep them high to avoid "Out of specification" dtcs.
And no, its not a 100% removal of the EGR in software.
Just an easy way to do it.
In Fiat edc15c's you will always have the DTC "EGR error" as far as i know.

"Hardware" way by blocking the EGR pipeline?

Hi to all.I set all values to 183, but now when i drive around 30km in all range of rpm,ecu write P0404 error.


Some proposals what to change in ecu, to stop this error.

Yes,some Fiat edc15 have this problem,but not all,and get EGR error.

VAG doesnt gat any error after closing,its no real EGR Remove,but closing the valve simply.

Try closing EGR only after 50% of accelerator,so while you drive normally egr can work normally and if you need power and have lot of turbo boost EGR still closed.

If error persists,try more high accelerator value(LOAD)

Thanks rsibiza, i will change by this way and will test these days.

Thanks again, but why originally, this map have high value (194) in high load and low RPM?
