PRA ecu and Kpro III

[DH48]

Have a few question about the Kpro V3 and UK PRA ecu. First of all my build:
K24a3 EU accord type-S head and block
K20a2 flywheel
PRB intake and TB
EP3 6 speed transmission.
As this was an upgrade from a K20a2 i had before i bought a Kpro V3 for the PRA ecu. Now have come to a problem were i uploaded the TSX stock cal. so i would have the correct map but as the PRA does not have a wideband controller i was looking to enable the secondary O2 sensor. I have a Innovate MTX-L wideband and have used the narrow band signal for the O2. Here is the problem. In kmanger the "use secondary O2 sensor" for closed loop is grayed out. I disabled the OBDII check as some threads have instructed but still nothing. Is this from the TSX cal. i uploaded or am i missing something ?.

Odd thing is that the fuel system gives error and is always in open loop but the car itself runs OK. AFR is a bit lean 16,7 but not like with the stock virgin PRA ecu before.

Please post the calibration.

Aa sorry forgot that :)

Edit: just tried to create new kal. Picked the PRA K20a2 and now the option to use the #2 O2 with closed loop is open. So i need to modifie the K20a2 PRA base map as on the K24a4 TSX kal ?

Edit2: Problem solved just loaded new kal. for K20a2 EU PRA ecu and modified all maps to a mix of K24 accord and dual adapter TSX K24 stock kal :). Have closed loop again and car runs smooth.
