Default EJ20K vs EJ20G Maf Scaling?

So originally I was going to get a Z32 MAF to just give my car some headroom, but a EJ20K MAF w/ pigtail showed up for a good price. Since both of them are 80mm, the 20k MAF should plug in. The 20k MAF also has the pigtails so that makes soldering it in easier.

My main question is, is the EJ20k MAF scaled to the same degree as the EJ20G MAF? I'm going to get my car tuned with my PowerFc soon and I am wondering If the MAF scaling will need to be changed? It looks like this is an extremely common swap over in the UK, but information is lacking here. I know with the Z32 MAF, the ECU needs to be rescaled, but does the EJ20K MAF necessitate the same thing?

Edit: Is it the same as the Z32 Maf?

Isn't there a specific setting in your PFC for a Z32 MAF? I could have swore it had that option!

there are two different 20k maf's...the EDM is 80mm but the JDM is 90mm...the 80mm version is comparable to a z32 but the 90mm version is comparable the Q45

Is it also true that the usdm ej22e maf is similarily scaled to the ej20g?

Would like to use a z32 in my Eg33 with an SAFC.

The Ej22e MAF is the same part as the Ej20G one.

PFC l-jetro

After doing more research, the Z32 Maf would be plug and play, but it isn't worth it.
