Apexi Power Fc Not Running Afm On R33 How?

[Alpocolypse]

Can some one shed some light on this .

Just bought a apexi power fc for my 33. But the guy i bought it of was NOT running a afm . My understanding there is no djetro (map sensor compatible power fc) for r33 ....so how does it work?

[r32-25t]

Is it a Gtr or a gtst?

There has always (as far as im aware) been a DJetro for R33 GTR and recently apexi released a version for GTS-t so if the unit has the new EL scrèen (black background, yellow txt, nice and clear) then you may have a new model djetro
