"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
We can start manufacturing from a spreadsheet similar to [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
