Hi SaNdMaN,
Just to provide some technical context on why I’ve been hunting for the GB5T-14G386-ZA utility: it looks like this wasn’t just an internal leak, but was actively distributed in early manual mapping packages across several Ford enthusiast spaces.
I managed to locate historical documentation from an older F-150 Forum map update thread (specifically tracking the LST_ERR05 resolution era) proving that users were actively deploying GB5T-14G386-ZA.tar.gz right inside their SyncMyRide directory configurations. [1]
https://www.f150forum.com/f118/sync-map-update-lst_err05-479185/
The exact file architecture they used was:
-
Item1 =
GB5T-14G386-ZA -
Open1 =
SyncMyRide\GB5T-14G386-ZA.tar.gz[1]
Since it was verified to be running sequentially ahead of the heavy JR3T map chunks to prevent installation failures, it seems to be exactly the script required to clear out my 16GB APIM’s partition bloat natively. [1, 2]
If any archivists here still happen to have an old manual map package from that specific era sitting on a drive, please check if this file is tucked inside your folder structure. SYNCGen3.0_2.0.16074
