Summary of change:
v3.3_u010262 mainboard home-assembled Second Wbo2 needed some components (even for a mainboard, just request in order comment and gets installed for no extra charge). Installed Resistors: - R28 -100k - R29 -510ohm - R137 -10k - R140 -10k and Q14 FET Pin out: - EC18/1 WBO2_2 Nerst - EC18/7 WBO2_1-2 Pump- - EC18/8 WBO2_2 Pump+ - EC18/9 WBO2_1 Pump+ - EC18/13 WBO2_1 Nerst - EC18/17 WBO2_2 Heater - EC18/18 WBO2_1 Heater == Procedure to calibrate or recalibrate your WBO2 controller built-in to VEMS V3 == * Connect '''pump(-)''' and '''nernst''' with 100 Ohm * connect '''nernst''' and '''pump(+)''' with 100Ohm * Connect a LED with 1k series resistor (between heater out and +12V or +5V) '''Verify Pump-''' My board measure 4.05V '''Measure Pump+ and Adjust Pump-pw-zero ''' * Measure the voltage between '''pump(-)''' and '''pump(+)''' My board measure 0.8 mV '''Verify Heater''' LED lighting. '''Nernst-DC target''' Adjustable 450mV config and log Assuming you could free-air calibrate LSU4 sensors for both channels (after 2nd WBO2 components completed; and enabling 2nd WBO2 in config). Care to write measured Rcal (between Rcal which is not a real sensor-pin and pump+) and calibration value ? * 1st WBO2: LSU4.9 or LSU4.2 Rcal = 84.1 Ohm calibration= 148.7 * 2nd WBO2: LSU4.9 or LSU4.2 Rcal = 109.5 Ohm calibration= 169 * The second sensor can not be calibrated. http://www.vems.hu/filethingie.php?action=list&subdir=VacsiImre ---- '''Q''' Could you take a vemslog of 2nd wideband calibration sequence (from sensor cold), with the following options: * select inputs->knock sampling->realtime data option->ADC/Individual power * RPM = 0 (engine not running) * second LSU 4.9 probe plugged in and powered, in free air. * tools, wideband calibration, calibrate second channel (manual, not auto cal) * let it run for 5 minutes. * upload the log to your file area with clear descriptive name and link it here After receiving your logfile i will review and make suggestions on how to proceed. Best regards, Dave ________________________________________________________________ Hi Dave! A vemslog is upload. Vemsfile area- VacsiImre. Thanks Imre ---- Hi! v3.3_u08562 mainboard home-assembled fw 1.2.37. Szükségem van az AIM adatokra, a 125-ös csatorna adataira is, pontosan a warning lamp bitje érdekel. A régebbi fw tartalmazta ezen csatornát, viszont a többi csatorna hiányos volt. Most ami érdekel megvan, csak ez az 1 adat kell még. I need the AIM data, the data on channel 125 as well. Exactly the warning lamp bit interested. The older fw contained in this channel, but the other channels was incomplete. Now that interests you have, but this data has to be one. Thanks. Imre
