Added:
| Configure to display Lambda, not AIM |
| Solution for now: |
| Some round devices (notably those manufactured in 2021-09) were shipped with an unusual config, that displays AIM-data or -FU if AIM not received. Admittedly annoying. Sorry about that. |
|
Save config, edit vemscfg file:
* config.display_mode[0]=80 * change to * config.display_mode[0]=00 |
|
* device HW always carefully tested several times before sending
* If not actually using AIM stream, it can be reconfigured in 4 minutes. |
| And File/upload config. |
| That should display lambda, and not AIM (which is not received => indicated by -FU). |
|
We recommend to File/save config before proceeding.
* Also take note of some values (Advanced menu EGT and Wideband settings): * EGT calibration: 151-152 usually * EGT offset: 80..200 usually ** 0.5C / step, any value from 0..255 is normal if the device temp is roughly displayed as EGT temp when the K-thermocouple input is shorted * Wideband pump_pw_zero: 99 usually (or close, eg. 98 less often) * Wideband nernst_dc_target: 228 usually (mostly) ---- * Download [round_0.7.51.vemscfg] file to local disk * File/upload config to device (with VemsTune) ** (Advanced/) EGT offset might be changed, so adjust according to your records, or calibrate with K-thermocouple input shorted Alternatively: Edit vemscfg file: * config.display_mode[N]=0x instead of 8x * config.display_mode[N]=5x instead of Dx (but AFR is counterrecommended) * eg. (most importantly) ** config.display_mode[0]=80 <= display data from AIM input ** change to ** config.display_mode[0]=00 <= display lambda measured by device File/upload config (choose the edited vemscfg file). After that, device displays lambda, and not AIM (which is not received => indicated by -FU). |
