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?

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 # changed to 66resolved problem

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

PROBLEM SOLVED! wbo2_calibration was way too high (started out with A8) and all i was doing is going higher never tryed out to lower it (?!) then i tryed A1 and i get O2 something like 24.7 and i get 20.9 on 66 (hex) so i`m continueing my work...


Work progress:

I got spark,need to set Injector settings and start the engine for the first time.

Curently using stock coil and 60-2 wheel with stock VR trigger sensor,i`ll update it later to some 200sx COP's since i got them in my garage and i heard that they'll do the job correctly.
