on some cars, e.g. those of the vag group when you vary the map turbo it works even on the map N75 solenoid command....and it seems to me that maps an overboost does not c'? n? ..so going by logic the latter, I believe, vary really the time to boost or an overboost engine CR....
I have tried to modify the contrary,in small increments, but I tried...according to me, if done with knowledge and a thing possible...
in addition to this map, no one has ever tried to work on the PID parameters of the pressure controller?
these maps calls an overboost represent the position that should have the geometry, then the control unit should "chase" the pressure present in the map. The pursuit of pressure to the avr? a slowness in reaching the correct value, hence the effect of an overboost can also be obtained by changing the PID parameters that sometimes are found on the DAMOS.

to edit a pid control ? easier said than done...I do not s? explain well how it works why is this ? quite complicated, but many tuner even the famed s? who prefer not to touch it because of a certain complexity....
I've never modified on the ecu, but I've modified on petrochemical plants, doesn't it ? easy but believe me that you can do things much more complex.
It is important to have a clear idea of what you need to do, you do not need to make major changes to the parameters ameno that you are not changing the turbine.
In this case it would be appropriate to change the PID to avoid oscillations or inspection time is too long (effect an overboost)
exact franco..the change of the pid serves especially when you sotituiscono turbines (vgt with other large...more
not have the effect you describe you very pronounced and almost out of control with the management of the ori of the car when this happens many tuners prefer not to go crazy with the pid control of the ecu, but "bypass" the problem by mounting a controller vgt external...type the arduino for example....
I personally change them almost always when I try to l drive, you will see immediately the difference in the readiness and never had us in the modify indeed, according to me and a side dish that goes well when you're programming a control unit, of course, done in the correct manner without overdoing it
I normally on standard maps I prefer not to work on the timing of an overboost, but at the request of the customer on the maps pi? thrusts
I change them only at low x the speech 0/100
then I let them golds.
I touch them, almost always
Touched good only to take them anke 5 hp...then of course there are machines where should you touch them or not...
