Will update on the map in the back As I said I had pressure peaks at 1.7 bar. A Little many. I mod the map vgt and now I find myself in the press with a peak of 1.55 bar and 1.4 bar constant. I noticed for? that pi? you climb in rpm and less fuel inject. From the map we 100mm3 theoretically up to 4500rpm as set in the limiters. There will be? some other limiter. Advice?
What did you do exactly to adjust the vnt? For the limits diesel you've adjusted the maps lambda for the new device?
I suggest that you note how the turbo pressure to vary the rpm. The maps lambda do the rest...Originally Written by Already
I have heard of these limiters but there compartment looking as well I do..
this post ? really very very informative....finally something about the timing of an overboost I understood it....what's that for? I could not find....are the values of conversion to understand, in fact, the values of the map vgt what they are indicating....it should be the inclination of the vanes....but then, what is it that you refer?
If you open the map vgt with titanium, which gives you the value as a percentage of quelllo in diagnosis are with opening the valve. Some diagnosis the call opening the valve turbo, the other valve is an overboost etc.... Not ? other than the opening of the giometria variable, and then the wastegate
ok I found....and I indicates the 75% at idle engine....
so let's see if I understood well.....at the minimum, of course it is open why? at low rpm you do not need the pressure of the turbine,then accelerating as to raise the pressure closes up to the maximum indicated in the map to open then once the revs increase and there ? pi? need? pressure as always indicated in the map;
now if I wanted to work in order to have more thrust than that with the turbo pressure I could also work on the timing of an overboost and maybe prolong it for more and better stretch? of course, everything is always done with full knowledge of the cause....
No values are given in % of the closing of the vgt. Then the minimum will be? closed to 75%. At low rpm the exhaust gas are lower and, therefore, serves to hold the geometry p? closed to get it up to pressure.
However on a car stock 100mm3 them you can inject up to 4500 revolutions, are so many, and the car fumerebbe like a train. In my opinion with the original turbo are too many, even at low rpm, I am not going over the 90mm3 with turbo stock that already? are more? that's enough to make beautiful cv if everything ? well calibrated.
