Boost Curve

[prj]

Isn't this a bit like what Paul ( S2central) has already done with his V-stream chip? Its not to the extreme of 100% boost at any throttle but full boost seems to be reached at at about 2/3 throttle and is much more eager to get up into boost at part throttle than the 'standard' homefry chip.

Knowing him, he would never flatten the entire table, but it is easily possible to make boost more aggressive.
In motronic you have a 3D table based on RPM and Throttle pedal position. You can specify a value for 160 different combinations IIRC.

The only thing I don't like in Motronic is the overboost functionality, which depends on many conditions. I tend to turn that off, so that the boost is always the same at full throttle. Many tuners do the same.
Overboost is something different than talked in this thread though. In overboost mode it provides a bit of extra when the throttle is at 100%, based on a few parameters. This however makes boost unstable. It is also difficult to tune, because overboost is as predictable as a woman's mood during a certain time of month.

Thats correct .. as I said its not trying to make full boost at any throttle but it shows that - as you say - the boost profile can be made to behave differently with ecu tuning if you want it to. (overboost is switched off too).

Yup, exactly my point. You can make it behave any way you want to.
