What I know:

What I dont know:

Q: Shall I order 2+6 version, what can I use the 2 high current outputs for ?

A: Lots of things. Relay, solenoid, NOS, ...

Q: How about firmware and sensors, do I need to compile something myself ?

A: no need to compile anything. See VemsTune

Q: I suppose I should choose PS2 connector as well

A: useful eg. for wheel-speed input (but we can connect PS2 clock signal to an unused pin as well


VEMS info (I have bought a VEMS that came with this info:)

Board_version=v3.3

Serial_nr= 2267

pump-= 4.05V

wbo2_pump_pw_zero=0x64

wbo2_nernstdc_target=0x87

pump+= -1.0mV/200 Ohm

AREF=4.9V

(C103=1nF, no D100)


Other project info

I have bought a engine loom from a -02 VW passat that will fit the COPs.

Purchased a used WBO Bosch LSU 4.2 7090/91 as per below.

Will start making the new COP work with the OEM ECU to begin with.


Time frame:

2016-01-18

I have begun installing this now. I will make an adapter cable to fit the Motronic 55 connector at first. When I have it all working I will make a new wireloom. Maybe I will wait until nex engine takes it place in the car.

I started out connecting the Vems on bench to my PC so I could update FW. It turned out I needed to "lock" the CPU with direct programming. It worked nice but now I cannot update bootloader further because of "access denied". I have contacted vems and is waiting for an answer on that.

I want to have latest fw before I begin. I have also put together a cable for the LCD display.
