Hello,

Did anybody can turn on the Pol1 injection with the Boost transient recognition or alone?

I am working on my car Alfa GT 1.9 with GTD2056VZK (from Audi SQ7).
The ecu is: EDC16c39 Euro4 without DPF by default

I successfully turned on the Pol2 and injecting some fuel on -80 deg from 1500-2000 RPM so my poor boost improved much on this range. I have still no problem with the surge line, but simply closing the geometry does not improve the boost but choke the engine according to the increasing emap I guess.

I see a lot of advantage for improving the low rpm torque, or the response utilizing the Pol1, and it's boost transient recognition feature but anything I tried to switch it on is a failure. The same approach does not work which I used to switch the Pol2 on.

Does any have experience with this?
