Post AFR / Lambda PID from O2 sensor
on: November 8, 2021 (GMT)

I would like to get the real time AFR information (or lambda or both if possible).
The sensor is a Bosch LSU 4.9 (very common so…)
My ECU is an EDC16C39.

With the TECH2, I get those informations :

Translate :
Preheat
Preheat Temp.
Oxygen Concentration.
blank (in volts)
Lambda (but with very weird values… because, very rarely about 1 and on a range from 1 to 31)

With my OBD2 adaptor, I get those info in realtime, and I have access to the PIDs formulas :

acceleration :

The formulas used to get the same info as the Tech2 :

Do you think is it possible to get the realtime AFR datas ?
(14,5 at lambda 1 displayed)

Thanks for your help if you get time to lean on it.
