    E90 ECM VVT settings

    Does anyone know if there are any additional vvt settings other than the low, medium, high baro and WOT cam settings that need to be changed in this E90 for the 2019+ trucks?

    I just did a cam swap in my L87 and my cam is not moving when logging. I know it moved before the swap via logs and ive double checked those vvt settings but logs indicate its not moving and im only as fast as i was with stock cam and stock tuning. Everything runs great and no real issues that i can see. Timing is only at about 19* at wot for now and fueling is about 2+/- on short term fuel trims. logs and draggy runs prove my times are identical to pre cam swap so at least i didnt loose anything but I am second guessing my cam choice.

    Mods are BTR stage 2 truck cam kit from BTR with the 4* limiter, ported intake manifold, kooks 1 7/8 headers.

    Any advice would be greatly appreciated.

    Apply the values in the cam card regarding degree of retards , although that cam is supposed to be for 5.3 L83/L84 not L87 so it's kinda close to stock 6.2 cam .
