I don't think the engine management will like it if you blank the EGR on the 16v. However, it is worth it as a test just to see what difference it makes.
I just covered the last 1200 miles in my 2.4 JTD 10v CF3 (150bhp - not remapped) with the EGR valve capped off, between the EGR valve and the throttle body,and the EGR valve unplugged electronically. I did it by purchasing a second standard gasket, and sandwiching a cut out bit of Coke can between it and the two standard gaskets. It did remove a lot of hesitation below 2,000rpm. With the EGR valve unplugged, there was no engine management light illuminated, although a check on Examiner did show that the ECU had detected that the EGR valve was unplugged. Was actually pretty suprised the light didn't illuminate!. Only issue was a bit of a delay in turbo spool when changing up a gear, when the revs in the new gear came to around 2,000rpm.
I did a bit of investigation tonight and decided to reconnect the EGR valve electronically, but leave the cap in place, and have since done 50 miles like this, and this little 2k rpm bit of hesitation seems to have stopped. It now pulls very cleanly from low down, will report back on what it does to fuel consumption if anything.
Fuel economy didn't seem to change with capping off the EGR and disconnecting the electrical plug, around 450 miles to a tank local driving and over 600 miles to a tank on motorways. All in all very happy with the effects of the mod, but it does feel a bit cowboy. I'm working on a more permanent solution by totally removing the EGR system. At the exhaust manifold I will bolt on a standard flange that has had the centre filled with weld and ground flat, so no exhaust gas leaves the manifold. At the inlet manifold end, I am having a new 'throttle body' made up, which will also delete the throttle flap that my old CF2 didn't have. Hopefully this should smooth airflow into the engine and give a bit more power.
I do have in mind to remap the car and have the EGR turned off in the software eventually, but will be doing some more hardware mods first to get the most from the remap.
