Time is a limiting factor in my progress, but i managed to do a little in the past weeks. I have started to modify "config.txt" and "tables.txt", since i needed them to finish testing the hardware for !WBO2.
I adjusted wbo2_pump_pw_zero=64 for a target of 3.94V (it was the same value as the board was delivered with in the initial firmware).
Next I took the warmup parameters from Mik's Example files as starting point, and set the wbo2_ri_target=80 (128 ohm, measured on sensor's calibration Ri, pin6 on LSU04).
I connected a light bulb to test the warmup process, and it all went fine, with the lamp glowing gradually lighter as the warmup values changed. Connecting a 50 ohm resistor on the sensor inputs showed Ri=49 on the LCD, so thats OK, and the heater voltage dropped imediatly, as expected when Ri gets low.
Then i adjusted wbo2_nernstdc_target=A6 with LSU04 connected to give a measurement of 0.45 Volt across nernst cell.
And finally i adjusted wbo2_calibration=C1 to give a o2 reading of 2095 on the LCD, as described in the html manual.
Last i tried to breathe on the sensor to see the reading drop to around 1800, and back up again in free air.
I have also connected LED's on all the injector outputs, the ignition out, fuel pump out, and put a ptc on the clt_in and iat_in. Then i checked all the output with the mdhXX command. And with the finger as input trigger i se all the injektors fire in sequence, and ign fire, and fp turn on, and wbo2 turning on, and on the LCD i can see all teh parameters change as. iat, map, clt, rpm stays on 1000 since i use 50Hz stimulus on 6 cyl, coil type trigger with 6 teeth per cranck revolution (coil in distributor) configuration.
Still need a lot of decissions to make in config, and tables. But now the hardware seems to be tested OK. So maybee it's time to put the vems in it's box, nd start to plan the installation in the car.
