What wiring diagram use
« on: November 23, 2019, 12:51:09 am »
I bought used Vems with some wire harness that was instaled on BMW m54 engine.
I checked with vems v3.6 wiring diagram,and almost nothing was like in diagram.
The wideband sensor is in diffrent pins,5v doesnt have pins etc.
My question is,can I make a new harness like in v3.6 diagram or I need use some special one. I want to instal it on BWW m50 turbo engine.
I add some pictures,from my vems inside.
Sorry for my bad english,hope you understand me.

This unit is built by me years ago. Almost everything matches with Wiring. 5V. wide band.

18 pin connector:

1 not used (may be used for analogue input)
2, 3  analogue inputs 2 and 5 with pullups.
6 analogue input 6 with pullup
12 Exhaust cam Hall sensor.
14 Knock 1
15 Knock 2
16 analogue Ch 0 or 1  With no pullup.
17 GND from unit.

No speed input.

36 pin connector:

Injector outputs are A B C D E F
G and H are for IACV

Ignition outputs are that TO220 row: 0, 1, 4, 5, 6, 7

Outputs 2 and 3 are dedicated for VANOS pwm valves

Wideband is LSU 4.2

LCD DSUB9 pins did not matches with official.

What else?
