I want to get an accurate Air/Fuel ratio readings whilst driving. Does an Apexi and commander give this information. Also can the A/F be adjusted by the commander. Lastly, is an Apexi/commander compatible to run a stock auto FD.
No, the Apexi or commander does not give AF readings.
You need a wideband controller and Bosch 5 wire lamda sensor to read correct AF readings.
Yes you can adjust the fuelling using the Commander to the Apexi ECU.
