After making the connection, it is indeed necessary to calibrate or rather make a table of values in Volts / AFR / Lambda to interpret the values it returns in 0-5 Volt. There were no problems, everything worked correctly. The goal is to perform Datalog then reverse the normal 0-1v connection. I made the connection using a 3-point inverter key, so that going from 0-1v or 0-5v is in just a moment. Intercepting PIN 21 of connector B136 of my ECU.
The table that the wideband brought me helped. but he still needed a parameter data collection to have the initial calibration. observing the read AFR and at the same time taking note of the value of Voltage that the datalog throws.
At the same time, varying the fuel load compensation allows a specific rpm range to be varied in real time at an AFR / lambda range in order to take the necessary readings.
