    Are the injectors 42# at 4 bar?
    Is this an automatic car?
    Where are you located?
    Who did the tuning on this? Post up your stock tune or PM me your email address and I will try to help you out. Also, provide an entire list of modifications.

    Did you try taking timing out of the .16-.52 range where you are showing knock? I have a similar setup and my main spark tables are a lot lower in the idle area.

    Map is reading 80+ kpa with the throttle at 0%. Looks like maybe a big vacuum leak?
