Summary of change:
'''V3 to send a linear wideband output signal to a 3rd party device''' ---- '''Similar apps''' * Round is frequently used to send out analog (or PWM) WBO2 data (or "emulated narrowband") ** MembersPage/ToyotaPriusLpg since Prius ECU likes a bit fluctuating NBO2 signal (around 0.45V around 1.0 lambda), that is also implemented as a special case * v3 is rarely used to send out analog (or PWM) because usually v3 controls itself, and '''v3 can send out in digital form with CRC protection''' (AIM format, or VEMS triggerframe format, or 2nd serial modbus slave RS485 or RS232 connection : with custom compiled fw used in powerplants; modbus master is also possible but that is really special, not normally used) '''V3 with lambda output was used''' in Fefe's Lada Samara which historically had 3 ECU: * factory gasoline * +addon LPG * vems v3 ECU for logging, and cheated nbo2 output: '''Fefe's HW had a 5V output and a voltage divider of 5.7: 1k/(1k+4.7k)''' * Max rich 255 * Stoich 131 (0.45V) * Max lean Y=0 (0V) * as this was implemented with an internal 17 point table called narrowband_out (and interpolation), it is easy to change to other curve (linear is also easy). It was a bit special, we need to check how it can be configured currently (possibly adding some config options is justified ?). ---- An OEM ECU in this case. This can already be done with a Round display, but as discussed, this would be possible to do with a custom (or new standard with some new options) firmware on the V3 as well. If possible we would like to get the same signal that the round can send on the analog output when vout_conf=5, which is a wideband high resolution linear output (0..5V) There is really no need for any configuration options for this, everything can be hardcoded if such feature is not wanted in the main-line firmware.
