Summary of change:
'''"BMW M60B40" EC36/18 - mot88 pinout''' V8 with 8 passive igncoils '''VR,VR ''' (m60b40 is VR/VR so no 3d trigger ! No VANOS at all. * the NFETs are only for idle than. NFETs controlled from S259/1-2 are best for idle, (not "inverted p259", but either works) '''Engine specs:''' * Engine designation M60 B40 * Engine code 40 8 51 * Design 90° V8 cylinder * Displacement 3982cc (243 cu. in.) * Compression ratio 10:1 * '''Firing order 1-5-4-8-6-3-7-2''' ** notably cyl 1 and 6 are friends (opposite cyl), like in the 153624 ---- '''Ignition outputs - ign dualout capable. Bolded those different from M50-Vanos pinout''' * ign1,6 ignch0,'''1''' tracecut * ign5,3 ignch6,'''7''' tracecut * ign4,7 ignch2,'''3 wired''' * ign8,2 ignch'''4, 5 wired''' If v3 fw allows 7,0 to be igndualout neighbors (without inverting), than cyl6=ignch7 could be an option (only 2 tracecuts total, not 3; no big deal though). ---- '''EC10 male recommended pinout''' (always check the docs included with the device) * pin1 - not connected (could perhaps connect some mcp3208 analog input? 2 NFETs already on pin8-9; Other 2 NFET outputs are used for idle?) * pin2 - Mcp3208ch1 * pin3 - Mcp3208ch2 (pullup) * pin4 - Mcp3208ch5 (pullup) * '''pin5 +5V''' * pin6 - 2nd wheelspeed * pin7 - 3rd trigger HALL input * pin8 - NFET ... * pin9 - NFET ... * '''pin10 GND''' ---- Starting manufacturing from a '''spreadsheet''' similar to [http://vems.hu/download/v3/Motronic88/M50-vanos-vs-s50b32.xls S50B32] that clearly specifies '''EC36+18 - Mot88 mapping''' (with some ign remapping, respecting ign dualout compatibility) and Assembled ECU specs similar to ('''might be wrong, PLEASE EDIT'''): '''ECU VEMS V3''' - primary_trigger: EC36/27 VR - '''secondary_trigger: VR''' (not HALL as in earlier order) '''mot88/pin17 should be sectrig VR input''' (mot88/pin44 should be CAM GND) - Flyback: High Z-only 30V flyback - 1-wire interface: no - ETC BridgeOutput_Interface: 0 - Hi-side PFET outputs: 4 '''Actually 4 NFETs, not PFETs''' - ignition driver: 8 - LCD connection: yes - Knock input channels: 2 (not 0) - MAP connection: 400 kPa simplenipple (actually external MAP sensor included, SSC5...) - EGT input: 0 .. 2 '''DUAL WBO2''' (previously requested for same engine) ---- '''Other outputs (generic note, not M60B40 specific)''' More NFETs or PFETs on flying (for ex. boostcontrol?) possible ? * possible upto 4 NFETs + 4 PFETs total ** should be more than enough together with the stepper outputs, +2nd WBO2 heater output ** possibly 2 extra-FET outputs + a couple other PWM outputs from connected round (AIM stream sent via 2nd RS232 TX) ... unlikely to be needed ---- '''NFET output''' * '''mot88/pin2,29 are idle, NFET clearly best (does not matter if inverted or not)''' * '''mot88/1=FP relay''' (p259 or NFET should do, but not inverted if possible). * '''pin27=ECM RELAY CTRL ...''' ** isn't that a problem if inverted ? That means it '''turns on automatically at powerup''' (eg. if not configured, or firmware+config not running at all for some reason). ** '''for ECM or FP Relay it sucks if ON when not configured indeed''', better redirect those control channels to S259 out 1/2 ** OK, so they best to be controlled from S259, not p259 inverted (even p259 is better than p259 inverted). That way relay only activated intentionally * need M60B40 units to '''have NFET outputs''' (on P259 or s259) ** NFET on p259 are activated when p259 NOT activated (so inverted). ** They may, or may NOT need to be inverted in config depending on what is controlled (eg. boostcontrol turbine bypass valve pneumatic actuator TOP/bottom, how the 3 way valve is connected pneumatically, ...) ** need to be inverted in config for "normal" function, yes ** '''practical test: temporarily set as MISC2 output, and toggle the "inverted flag" while measuring from +5V as a base''' *** -5V means NFET active pulling to GND *** +7V means PFET active pulling to +12V *** 0V means inactive
