Aldl afr on 6395

I tryinge to aldl afr instead of fuel pump voltage.
I found the adress afr $026D in a hack and enterd the adress to L522E instead off the $ 0055 (fuel pump) it looks like it follows the command from the ecu not realtime afr.
Is this the wrong adress for it cant find another

L$026D is "Commanded AFR". That is the only AFR term there is. The PCM has no way of "measuring" real AFR. The narrow band O2 sensor is not capable AFR measurement, only switching above and below the stoich AFR for gasoline, 14.7:1. If you want to datalog "realtime" AFR, you will need a wideband O2 unit such as the LM-1. HTH
