Thanks Cintack, but still it has problem.
He still gets wrong metrics and the data it reads is wrong and going up and down..

Is there anything else we should check.. He has the same engine and the same adapter..

there was an error in the formula, I did not check, but just copied
in the formula you need to divide not by 255, but by 65535
in line OBD Header write: 7E0

in the screenshots of the above test pid, it is generally unclear what’s going on, all the answers on the 01xx mode
maybe a formula and the right one, but at first glance it’s not logical, although I looked at your old logs, the first byte is zero all the time
I think this formula will work
B*191.25/255-48

in detail write about your car, model, year of manufacture, engine, to accurately know what kind of car you have

adapter you have with bad firmware, it does not understand the command to select the address of the block
should be both on average screenshots in the adapter verification program
