Visit Preferences to set your user name Summary of change: Started setting up my WBO2, as per the[http://vems.sourceforge.net/manualhtml2/ch07s02.html manual] '''Adjusting "pump zero pw" dutycycle''' # In MegaTune, under settings then under wideband settings, changed the Pump zero pw (wbo2_pump_pw_zero) to try and get pump+ to pump- = appr 0 Volt. I was getting absolutely no change at all, it was originally set at 102 and read 0.4v. I finally realized that after adjusting and saving the value to EEPROM (mcs) ECM reset (eg. BootLoader flash-checksum test, or power down/than up) needed (or trigger or force WBO2 on with ''mde02'' than off with ''mde00'') so the new value actually gets used. Ended up at 101 (0x65) made 0.1v. Type Mcd in terminal program, got wbo2_pump_pw_zero=65. Perfect! #Took me an hour to figure that out, next step will have to wait till another day. # Couldn't wait, on to the next section: (this is also pump testing!) # Readings (with a stolen config.txt) were *Measure the voltage between ground and pump- (pin 5). 3.98v *Measure the voltage between ground and nernst (pin 1). 4.32v *Measure the voltage between nernst (pin1) and pump- (pin 5). 330mV According to the[http://vems.sourceforge.net/manualhtml2/ch07s02.html manual] that is wrong, so I adjust it. No lcd yet so doing it through MegaTune, kind of a pain actually. Setting the wbo2_nernstdc_target did not do much of anything, and I had to restart my board every time for changes to take effect. Set it to 0x96 and went on to adjust wbo2_pump_pid_ki. I noticed that they did not multiply to 0x4000 so I adjusted wbo2_pump_pid_ki to 7C and now I get *Measure the voltage between ground and pump- (pin 5). 3.98v *Measure the voltage between ground and nernst (pin 1). 4.41v (+/- .02V) *Measure the voltage between nernst (pin1) and pump- (pin 5). 430mV. Actually fluctuates between 420-440 but that's OK # Played with the rest of the settings.
