If I'm not mistaken, the ones with the percentage they are used in the rapid transitional, for example, when you press the accelerator, immediately after the pressure is correct with reference to the map ( rpm / diesel) ... Virtually ? a controller in open loop and a closed-loop....
I don't know if I explained it well...
but it seems to me too simple, so I'll give you an example, I injection approximately 100mm3 of diesel, the map is set at 1.4 bar maximum, lowered values an overboost up to 10%, the pressure I get to 1.4 then climb still to 1.6 bar, I want to avoid this and to avoid that, I want to understand the operation
monitors the opening of the vnt, the gas, the rpm and the measured pressure, then see if the variable geometry does or not his work!Originally Written by tidus1985
You monitor the geometry v. With all that diesel, perhaps, the geometry can't manage to do better. Maybe ? already open to the maximum!? This I do not know to tell you because they have never come to those courses with my... 100 mm3 are really many, 1/3 more of the original...
here is the log, aime having multi ecu scan and edf that I get stuck smepre I have been able to monitor only 4 parameters and then pressure turbocharger goal, but I've attached a re+mod, anyway ? 1.3 bar maximum, the diagnosis reads me a maximum of 1.45 bar but the pressure gauge depo that does not ? a simoni and a pilot I law 1.53 bar, so I think maybe it was the pressure sensor? I attach a txt file with the log and maps
no, not arriver? never at the bottom of the scale even with the diesel, unless you have the spring off, but if before it goes to 1.4, then 1.6 a cause can? be l
The gauge will read the pressure on, the diagnosis or the absolute, you have to consider that the atmospheric pressure does not ? exactly 1bar...
the cio? what do you mean? at the minimum, in fact the pressure gauge reads -0.1 bar, it has both hand and digital display, stepper motor, and anyway, with the map in 1.3, the map overbost lowered salt +0.15 bar from the diagnosis and from the pressure gauge goes over 1.5 c'? something that noncapisco, the geometry does not ? locked, I checked
I have seen the logs according to me you have to drop the variable geometry, in acting on the maps *1DF642 and *1DFB0E the change in the axis of the turns you made on the previous one I do not like, even why? these are perhaps among the maps pi? complicated to tap, I would start by leading (3-5%=300, 500 points) with the maps described before, in particular, on the column of 80mm^3/the...
I missed that in order to obtain the percentage of the variable geometry you need to multiply the values that you have in the map for 0.0122
