Summary of change:
'''BMW S50B32 outputs''', subpage of MembersPage/SFiftyBthirtyTwo Straight-six engines typically use a '''firing order of 1-5-3-6-2-4''' ---- '''Vanos related:''' MembersPage/SFiftyBthirtyTwoVanos ---- '''Ignition outputs (and fuel pump, main relay, IAC, ...)''' [http://vems.hu/download/v3/Motronic88/M50-vanos-vs-s50b32-vs-M60B40_B30.xls M50-vanos-vs-s50b32-vs-M60B40_B30.xls] ---- '''Ignition outputs''' - all tested, found good * cyl 1 ignch0 - MOT88/25 * '''cyl 5 ignch6 - MOT88/52''' also good, as the others * cyl 3 ignch2 - MOT88/24 * cyl 6 ignch1 - MOT88/51 * cyl 2 ignch7 - MOT88/23 * cyl 4 ignch3 - MOT88/50 We received a device with reported ign cyl5 problem. Finding that outputs were good (also tested with load), it was a bit puzzling for quite some time. Since the HW actuates all outputs, the only possibility we can think of that the home-swapped IGBT legs (bent incorrectly) contacted the clamping plate, causing problem. '''Other:''' * '''IGN 5 - MOT88/27 main relay''' * '''GND - MOT88/7''' (correctly soldered as GND; not IGN 4 as M50 vanos) ---- Config saved from return device [http://vems.hu/files/MembersPage/JuanC/S50B32/Report-2021.06.14-14.57.08.zip S50B32 config] Default config [http://vems.hu/filethingie.php?action=list&subdir=MembersPage/JuanC/S50B32/v3.3_u013410-A-2021.07.15_default_saved_from_ecu S50B32 defult config] * Please compare to known good, and see report text. * Most attention : * idle output(s) * '''ignch6, cyl 5''' ---- '''Injector (lowside NFET) outputs''' * CYL1 INJ C - MOT88/3 (EC36/8) * CYL5 INJ B - MOT88/31 (EC36/19) * CYL3 INJ A - MOT88/4 (EC36/7) * CYL6 INJ F - MOT88/32 (EC36/18) * CYL2 INJ G - MOT88/5 (EC36/6) * CYL4 INJ H - MOT88/33 (EC36/17) ---- '''IAC Valve (ICV) outputs''' * ICV-opening: INJ E - MOT88/29 (good) (EC36/9) * '''ICV-closing: INJ D - MOT88/2''' (EC36/20) * good according to [http://vems.hu/download/v3/Motronic88/M50-vanos-vs-s50b32-vs-M60B40_B30.xls M50-vanos-vs-s50b32-vs-M60B40_B30.xls] ---- '''Other outputs:''' * AC output ? * ... ? ---- All details about the wiring is in this file http://www.vems.hu/files/BMW/E36_Sedan.pdf Page 145 onwards.
