    Gear depended boost

    Tried this a bit today and it seems to be bringing boost up and down as i presume vems is trying to figure out which gear is being used. It could be a problem with the speed sensor hz value which currently is 255, but has anyone had any luck with this one?

    did a few more tries, and left it until i contact Marc. sensor either needs realtime calibration, or i dont know what else.

    boost however still oscillates no matter if it is gear depended or not.

      That is pretty sweet. It is more applicable to traction limited cars, but if you can force more boost pressure in 1st and 2nd while not going over the limit in the higher gears, that would be great.
      Did some tweaking over the weekend and saw 2.1bar peak in 2nd and 2.5bar (hehe) in 3rd and 4th. I have rerouted the signal for the MBC to take pressure reading from the boost pipe instead of the outlet of the compressor, should help combat boost sag (were only seeing 1.7bar at redline before)
