G450x Throttle bodies

[Bloodybigaussie]

Hi I have looked all over and can not find which is throttle sensor 1 and which is sensor 2 when trying to set my KMSK16 Adjustments. I have even checked the CD that came with the 450. To me it seems there are only 2 choices BUT if I get one right the other seems to blow out into the red way over the parameters hope you can help. Frustrated Aussie
