First V8 quad VANOS app fully controlled with VEMS was BMW S65 (and S68)
- with [Internal CAN]
- by Valdas (thx for useful feedback).
- BMW S62 has "dummmy" ETC (single motor controlling both banks), so actually simpler: no CAN-bus install needed; [standard VEMS] but order comments are important
- previously most installers just controlled the two intake cams (and leave the exhaust cams, exhaust cams not nearly as significant for power as intake cams)
5 triggers for Quad vanos
S62 needs VR, 4xHALL
implemented VEMS fw >= 1.2.36
- select 4cam mode
- actuators (see below) can be single PWM output per cam, or:
- optional: dual vanos type (eg. S62) => 8 actuator channels
Vanos output actuators
write in order comment: BMW S62 needs 8 x highside PFETs indeed, (eg controlled by 8 p259 outputs; firmware supports it of course)
