Is anyone running with 20AM air flow meter ?

I am about to switch to a 20AM AFM on my 4.6 chim and would appreciate any wisdom from someone with same upgrade.
In particular dors anyone have a 14cux fuel map

Thanks folks.

Mark you mention 15% difference between 5am and 20am.

I assume that is the 20am will read 15% lower as air velocity across the hotwire will be lower vs 5am for same volume of air passing into the engine.

With that in mind is it just a case of upping each fuel maps cell by 15% using Tunerpro ?

Thanks for that will take a look in TunerPro.

Incidently I fitted the 20AM and it does run.

Not sue whether to go for a RR remap or fit wideband lambda and diy it.
