PRA ecu and Kpro III
Posted: Sat May 31, 2014 10:49 am
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.
