BMW M50 Vanos. v3 srl=13013
- [configs] (since srl is 13xxx)
- appropriate vemscfg to start: http://vems.hu/download/v3/Motronic88/base_M50_vanos_1.2.31_srl13xxx.vemscfg
- as originally uploaded (not the srl107xx or the old base_M50_vanos_1.2.31.vemscfg , sorry for the misinformation: it was late night, and got no one in the lab to doublecheck)
- of course calibrating TPS and lower req_fuel OK for big injectors
His orig config was quite close, except some minor calibrations (sound good), and:
-prohibit_config=00
+prohibit_config=80
Was that intentional change ?
Ign output see m50 VANOS column in [xls] , this is igndualout compatible (since opposite cyls are driven by neighbors 3,2 ; 6,7; 0,1)

MOT88/pin27 main relay, activated by MISC1 output (ignch5)
- ignch5 as in the xls (equivalent to EC36/pin12)
- misc1out_channel=52
- configured always active (0-25500 RPM, 0-100% TPS, 0-510kPa MAP, ...)
MOT88/pin7 Vanos actuator activated by ignch5
misc2out_channel=42 (ignch4);
- activated 100 < RPM < 4900 (just ON/OFF vanos, not continuous VANOS ; no feedback loop)

customer states 2 coils aren't operational after loading the file from download/v3/Motronic88...
I opened the brd file in Eagle, grabbed a connector to count pins. mot88 pin 23,24,25,50,51,52 are the coils according to both "M50-vanos-vs-s50b32.xls" and bmw_pinouts.xls (both in the downloads Motronic88 directory. Eagle has Drive07 -> mot88/23,
| BMW mot88 | description | v3_output (Eagle BRD verified) | baseM50vanos config | What it should be |
| 23 | ign cyl 4 | drive07 | drive05 | drive07 |
| 24 | ign cyl 6 | drive02 | drive01 | drive02 |
| 25 | ign cyl 5 | drive00 | drive03 | drive00 |
| 50 | ign cyl 1 | drive03 | drive00 | drive03 |
| 51 | ign cyl 2 | drive01 | drive02 | drive01 |
| 52 | ign cyl 3 | drive06 | drive04 | drive06 |
Interestingly, drive04 and drive05 are the channels the customer says doesn't work, which backs up the hardware findings. According the the brd file, drive04 goes to mot88/7 which is vanos solenoid on the m50vanos, and drive05 goes to mot88/27 which is the main relay activation.
So it appears our default config for m50vanos is bad in the ignition output area (at least.. that's where my focus has been so far).
