KPRO4 loosing readiness when turned off.
All,
I have an AP1 with KPRO4 on PRB ECU .
I have checked power and ground on ECU B connector , pins 21 for battery power and the various brown/yellow grounds.
I have 12v+ when the car is off to these connections.
The diagrams I have seen from the PRB RSX ecu show this DTC power being required from E7.
I cannot trace continuity from B21 to E7 on the HONDATA ecu so I suspect theyve done something else.
I have passed NYS emissions before, but am feeling like the ecu is loosing battery power somewhere.
I can run 1 drive cycle and have all readiness completed. If I turn off the car from the ign switch and start back up I will loose EVAP & my 2 O2s.
Does anyone know where we are keeping the DTC memory happy on the KPRO setup?

Heres what I've got now. The CRK is taken care of.
I can get both O2 - o2 / heater to clear , EVAP will too if I run the car around.
I did shut the car off, cycle back to ign on and scan & the 2 O2 readinesses stayed, only EVAP blinking.
If I let the car sit and then start and scan, I loose all 3 readiness.

Maybe I've just lost my mind so let this be a blog post...
Imported a PRA map, selected only wideband and let the radio buttons do their own thing.
If I run for a bit the below completes.
Scanner is as follows , even after a good amount of off time.
only ELD and Purge is enabled on KPRO.
