Hello Guy's .
I am working on a Peugeot 207 with MED17.4.4 ECU and 1.6 THP engine . Basically the same as Mini R56 hardware wise except the Mini uses MAF and Peugeot Uses MAP to figure out load.
The version i have has only one cam Phaser on the inlet side.

I have a set of cams in it:
Stock:
237°/241° - 190°/195° - 9.05mm/9.00mm - 0.00mm/0.25mm
The Set I have:
241°/242° - 200°/201° - 9.25mm/9.25mm - 0.00mm/0.30mm

I think it may be beneficial to try and make some small change to the Intake cam angle at high loads but the table for cam angle ad general conditions confuses me a little bit.
Here is the cam angle request table ( or i think so ) . I am a little puzzled from it.


the cam control is 0-36 degrees and the locked position is 36. As far as i understand from other variables and if my understanding is correct i am puzzled by that table.
If locked is 36 then when the table says -20 then the cam is actually sitting at 36-20 . then i have the issue at  the end it goes to numbers that are positive 5,7,13 .... witch should not be possible.

Maybe i am looking at the wrong table and table. Here is also a list of all cam related maps i found:


I will appreciate any help .

Just a follow up. I have tried to make both areas at 2k and 2.5k at 160% to 0 then slowly blend it at 3k  at -10. i made a small adjustment to
KFMIRL as well but it seems my direction (at least in cam angle is not correct ) is not correct. I will keep experimenting and probably get some inormation of my testing here .
