Default LNA1620AA

I have searched X300 section and found numerous posts re XJR6 MAF.
Most dealing with how difficult it is to find a part.
My searching the web has pointed out that the same MAF was used in Range Rover and SAAB.
Original Bosch 0280212013 is referenced as LNA1620AA.
The SAAB was a 2.0 litre. AJ16 4.0 litre. Would they really utilise the same MAF?
I am sure that I aa not the first to go down this path. Has anyone confirmed that these parts are interchangeable?
Cheers.

The MAF sensor on mine for the normally aspirated is marked as a Lucus 20 AM with Jaguar # LHE1620AA

I keep a spare for down the road

The max flow rate for the normally aspirated engine is around 175 grams / sec and for the supercharged around 225 grams / sec

I don't have the Lucas # for the supercharged

The problem with putting the wrong MAF sensor on is the response curve as the ECU return signal to the ECU are not the same to be accurate in engine regulation

On the upper end of the curve is called the saturation point which becomes a bigger problem if not addressed with the proper MAF sensor

They use the same LHE1600AA on the short stroke 3.2 liter AJ16 Jaguar same engine block, different ECU maps for engine regulation
