Power fc wont save changes

Bought a civic with a swapped jdm b16a running an obd1 loom and a stock jdm ecu. Anyway bought a power fc and a obd1-obd2a harness kit and had my tuner tune the car. All was great on the dyno but when we turned off the key and restart, the pfc would have the base map.

Have not seen this problem on hondas but common with silvia with swapped motors where the eccs ingnition is not wired correctly and cuts power immediately and doesnt give the fc time to save the data

Does the honda wiring have the same setup with a relay switch to delay power cut to the ecu on shutdown? Anyone have the wiring schematics plz

Thanks

No delay relay, you switch off the ignition and power is lost to the ECU IG source immediately, that is why the ECU is wired with a VBU to keep constant 12v for memory.

Thanks buddy. My tuner said he swapped 2 pins and the power fc is now holding the settings when saved using the fc commander. Car goes back on the dyno maybe today so hopefully all is good when saving changes using the apexi pc software
