Yet another injector topic..........
Long story short, on 1.9td :
Boost is at 12psi;
Fueling is entousiastic yet not too agressive;
Timing is conserative : tuned by a garage how works by-the-book, would not go to .95 or .97.
Compression is rather good (410-415).
Performance and fuel consumption are ok but not great (aroud 7.5 in normal, mixed not too agresive driving conditions);
Cold start is far from impressive (-10 C at worst... yet).
I guess I should first have my timing higher (tough of .95-7 because I don't want the thing too noisy).
There is a lot of things that can be done to upgrade our engines, but it seems that good injection is often negliged. Why go to 15psi boost if your injectors skirt a jet rather than a mist?
Question is : could the injectors be the next to look at?
What kind of expense should I expect? (thight budget here :roll: )
Thanks!
Ho! One more thing : with a little more fueling, it is hard to get the idle down to 1000rpm... I did reduce residual fueling a lot, almost at minimum... Could injectors release the fuel to easyly?
