Installing VEMS on M20B27 BMW engine.This is my first VEMS project,and first standalone project ever,so i would need all the help i can get! :) Tnx

My goals are to get NA engine running on VEMS and doing a few dyno runs,paint car, then go turbo.

I finished my harness few days ago,waiting to get some time to try if i got spark,then i`m going to wire everything else to Genboard and try to start the engine.

Current engine configuration:

Dyno results with 205/50 R15 159,6HP and 230Nm

Planned configuration for turbo:


Sensors

I`ll be using onboard 400kp map sensor I`m using M50 TPS fiited to M20 intake I`m going to use one from FIAT Punto 1.1,its like "Temparature Sensor" from webshop just its fitted in nice plastic housing.

Ignition

A: For the NA engine,that i`m curently working on,i`m going to use stock coil,with turbo,yes,i was planning to use 3x2 wasted spark module from Opel Omega B,Vectra B,Calibra V6 (same bosch number as one from the webshop]


Fuel Injecton


Problems:

I finished the harness so i started to calibrate and set up the "things".I have problem calibrating WBO2,i cant get O2 readings...?

This is voltages that webshop sent me in my email,should i try to get this voltages?

The details of your Genboard:

Board_version=v3.3

Serial_nr= 1036

pump-= 4.15V

wbo2_pump_pw_zero=0x68

pump+= 4.31V

this is my config:

> wbo2_abs_limit=E4

> wbo2_limit_maxt=A0

> wbo2_fallback=B0

> wbo2_retry_t=06

> wbo2_edgetime_corr=BA

> wbo2_edgetime_min=50

> wbo2_ri_target=00

> wbo2_nernstdc_target=7D

> wbo2_pump_pw_zero=68

> wbo2_calibration=A8 - i tried this one with larger value,no results

> wbo2_heater_pid_kp=46

> wbo2_heater_pid_ki=10

> wbo2_heater_pid_kd=1A

> wbo2_heater_pid_ilimit=80

> wbo2_pump_pid_kp=15

> wbo2_pump_pid_ki=4E

> wbo2_pump_pid_kd=00

> wbo2_pump_pid_ilimit=84

> wbo2_ri_confidence_scale=80

Heater is working,the sensor is little hot when i touch it after some time.While sensor was outside,not in exhaust,while i was assemblimg the unit i saw some readings,but now when everything is ready and i got all harness done and sensor in the place where stock sensor was,no readings.

How is possible that i had AFR reading at page2 after some time (mlp02),heater was on,so instead of geting O2 i get AFR readings,Engine off, Like this:

...

AFR:20,98 O2:??.?

AFR:9.09 (or ??.? this is target afr or?)
