Modification times of an overboost: yes - no

Sandro negative? if, for example, at 3000 rpm and full load you have the 30% of opening the ports to zero or by a percentage?

[SandroMarciano]

usually I try to drop 100 points at a time and see how it reacts, I think that in the regulation it is necessary to proceed in an empirical way... usually to my goal ? to be able to hold the peak up to values of 0.1 bar above the map objective, then I have to check to diagnose if the valve opens and closes continuously or remains on a fixed percentage. In the case that does not converge it is necessary to retouch the PID controller

[Chris156]

Have you ever tried to put a zero in the total laps and see what happens?

[SandroMarciano]

no, but I do not care to try, I think that the result would be what would take appropriate action to continually PID controller to return the pressure around the set in the map.

I am convinced that the original time of an overboost should be fine! then depends also of which turbine we are talking about, and if one wants to take that much of a turbine, have to worry about, s? pressure and boost, but more importantly the EGT!

are importatissimi also tours!otherwise collapses

I agree with guido heel.

The problem is that if you increase the fuel (especially the one injected after TDC). Then, in my opinion, from what I could see after 150000km many turbines you starano.

I agree.. I have noticed the ch and on the fiat this is what happens! I the boost, I leave the original when I know that I have customers picky and they want everything to last .But when they want the car to be pumped increase to 4-7% . I, with my car, I've done 150,000 km and now I feel that the turbine is ? slightly unbalanced.

Small question, what is it ? the map of fuel injection that regulates the flow rate of fuel injected after TDC?


thanks.

[SandroMarciano]

I do not think that there is a map that indicates the end of injection, end of injection should be calculated by knowing the time of injection and the advance

[savek]

I always leave the original
