    Default Dtuk crd2 map charts?? What do they mean

    This is a picture of the charts on my crd2 box what do they mean I have no idea?

    also I noticed up the top it says 1.9particulate would this still be ok on my non dpf vectra?

    i tried map 3 and power seems to kick in quickly but wheels seem to spin a bit much map 1 is ok and seems a bit smoother.

    still to try map 2 and 4 but would like to know what these charts mean

    Where did you get that?
    The boxes have processors that adjust the voltage fed back by upto 1 volt, those graphs describe the variation in voltage based on the fed back voltage. 160bar is about 4.05v, so you can see that the maximum pressure in the rail will be increased aswell as throughout the lower pressure range. Most maps increase rail pressure because it yeilds better top end power.
