Loading RV12is base config, AFCS .gca, and .ace files. Anyone done these recently able and willing to walk me through? Or talk about it online?

Just finishing up an ELSA RV12iS. With Garmin VFR Avionix and autopilot driven by the 3GX directly. Anyone willing to talk and help me down- and upload the Vans AFCS .gca and the .ace files? Main question is can I upload these 2 files without overwriting all the stuff I’ve configured previously? Like fuel calibration, etc. if so, how?
