Engine light issue - ecu?

Hi all, have recently purchased a 2001 1.8ltr coupe.
It has an engine light on constantly, when scanned (with proper workshop scanner) it shows no codes but when you change the scanner to a 1.5ltr lancer it shows a code for the mass air pressure sensor (which the 1.8 doesn't have, it has a mass air flow sensor.
The engine definitely is a 1.8, and has a mass air flow sensor. I swapped the ecu for one I bought that had an immobiliser delete, bit the code still shows. Also, the code on both ecu's are the same.
Furthermore I wouldn't worry about just an engine light but it's thirsty as hell, only 370kms to a full tank, and it idles up and down quite dramatically when it's cold.
Any help greatly appreciated!
 
Bad fuel consumption does ring of an air flow sensing issue. Is the timing correct?

MAF plugged in?

Factory airbox?

What’s the fault code exactly? Should be a two digit number.

Any other symptoms? Very uncommon to have Ecu failure
