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 * primary trigger ** sectrig (C103=1nF) ** thirdtrig (C105=1nF) ** 4th = wheelspeed1 input (C...<=12nF) ** 5th = wheelspeed2 input (C...<=12nF) Docs are not always exact about patterns, triggerlog will tell (of all 5). Consider: * If sectrig is exhaust, 4th trig is the other exhaust * if third trig is intake, 5th trig is the other intake ---- 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) |
