Default Problem with conversion to OBD1 on ZC DOHC OBD0

Ok, i had all stuff for for do it ago long time and today i tried to do conversion.

P06 chipped converted to P28 VTEC with ZC stock map (yes, i dissabled vtec maps and im sure i did another things right).

xenocron conversion harness to OBD1

TD043U , i had a problem with MSD cap of LS integra but i fix it and i think should works good.

i did my own conversion dizzy harness all right .

but i hooked up i get Solid CEL, from what i know that problem is normall a ECU failed but that ecu is OK since i was runing with my last EG6 B16 ,so ecu is good.

second thing i thought problem is conversion harness and then i was looking for some ppl with xenocron conversion harness and i didnt get none, i tried to search about this conversion and i found an info, that xenocron conversion harness is made for OBD0 VTEC ecus (PR3 maybe) to OBD1, then vtec harness is pinned differently than non vtec, so im not sure about if conversion harness would be problem since im sure i did all right.

any imput if vtec obd0 to OBD1 conversion harness is little different than non vtec obd0 to OBD1 conversion harness?

The dizzy has it built in. Did you wire it up right? Also did you try jumping the cel? Try a different ecu?
