C4 1.6 HDI DPF Off EGR romoval

Postby lucim12 » Mon Feb 11, 2013 12:45 am

Hy, I have removed my DPF via ecu safe, it seems to have worked , no fault codes, engine runing fine. Next I want to turn EGR OFF. Any Ideas?

Here is my modified file.

I have edited you post, you have reached 3 posts so you can upload your files now.
About your EGR thing, look for Hysteresis maps...:

lucim12, you kill you engine with ecusafe - this way of fap removing good only in edc15 psa ecus :), and for egr here is help:

Thanks for help nagliy_root

With ecusafe 2.0 did not work, too many errors, with the 1.9.3 version surprisingly did. got rid of regens and ran fine
with no p codes for 2000 miles now .
So after blanking the egr valve i got two codes "P2038 - Turbocharger Boost Sensor A Circuit High" going past 2.5 bar the car is much faster and pics up from lower revs now :evil: so tried lengthening the arm of the wastegate actuator to try to lower boost, which worked well :)
and P0401 Insufficient EGR Flow which doesn't go away neither with the map modding method.
