"BMW M60B40" EC36/18 - mot88 pinout
We can start manufacturing from a spreadsheet similar to [S50B32] that clearly specifies EC36+18 - Mot88 mapping,
and
Assembled ECU specs similar to (out of thin air, might be completely wrong, PLEASE EDIT):
1 x ECU VEMS V3
- primary_trigger: EC36/27 VR
- secondary_trigger: HALL
- 1-wire interface: no
- EGT input: 1
- ETC BridgeOutput_Interface: 0
- Flyback: HighZ-only 30V flyback
- Hi-side PFET outputs: 4
- ignition driver: 8
- Knock input channels: 0 (?)
- LCD connection: no
- MAP connection: 400 kPa simplenipple (actually external MAP sensor included, SSC5...)
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
