Summary of change:
'''"BMW M60B40" EC36/18 - mot88 pinout''' V8 with 8 passive igncoils '''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 straight-6 (more real BMW :-), so IMHO '''cyl1 and cyl6 ign and inj should be same mot88 pin''' as on M50-Vanos We can start 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''', and Assembled ECU specs similar to ('''might be wrong, PLEASE EDIT'''): '''ECU VEMS V3''' - primary_trigger: EC36/27 VR - secondary_trigger: HALL - Flyback: High Z-only 30V flyback - 1-wire interface: no - ETC BridgeOutput_Interface: 0 - Hi-side PFET outputs: 4 - ignition driver: 8 - LCD connection: yes - Knock input channels: 0 - MAP connection: 400 kPa simplenipple (actually external MAP sensor included, SSC5...) - EGT input: 2 '''DUAL WBO2''' (previously requested for same engine) ---- '''Other outputs''' 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 ---- '''Notes''' * need M60B40 units to have NFET outputs on P259 ** 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
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
