More and more I discover what a crock the standard programming for SI drive is. Its marketed as being a change in ECU programming making it change from economical to sporty to sharp.
Well we all know the S# is just S with a more sensisitve throttle map making full throttle at about 3/4 pedal.
Now I have noticed that I mode is merely a throttle shortening too I used to think that I mode limited boost to 0.4bar, but now I think its a function of partial throttle opening and no change in boost map
Has anyone noticed what happens when you have cruise control activated and you are in I mode? You can press the accelerator all you like but you will get no more than 0.4bar boost. EXCEPT if driving under cruise and it wants to accelereate up a hill or such - full 1.1bar boost is available to the cruise!!
Obviously cruise bypasses the SI drive - but it also demonstrates that the SI drive is not really changing ECU mapping - otherwise boost maps and ignition maps would be affected under cruise as well.
Just and observation and disappointing the SI drive could have been so much more. (and can be in aftermarket tunes from what I've seen)
