HPT TO EFI BIN CONVERSION (HPT to CTZ button):

Converts HPT calibration data to an EFI Live compatible .bin file.
EFI Live can open these .bin files natively.

How to use:
1) Click ‘HPT to CTZ’ on the Convert tab.
2) If an HPT file is loaded, choose to use it or open a different HPT.
If no HPT is loaded, you will be prompted to select one.
3) Module type (L5P, LML, E86A, T87, T87A, A50) is auto-detected from calibration size.
4) Choose where to save the output EFI .bin file.

E41 Controller Blocks (L5P):
EFI Live uses E41 controller blocks for segment checksum validation.
These blocks are preserved automatically when using the CTZ->HPT->EFI BIN
workflow via .e41 sidecar files:

RECOMMENDED WORKFLOW:
1) Convert your CTZ to HPT first (CTZ to HPT button)
-> Saves a .hpt file AND a sidecar file (.e41, .a50, or .t87a)
2) Make your edits to the HPT file
3) Convert HPT to EFI BIN (HPT to EFI button)
-> The sidecar is loaded automatically for valid EFI format

TCM modules (T87, A50, T87A) have EFI controller identification data
embedded in the executable. HPT to EFI conversion always produces
valid EFI Live compatible .bin files for these modules.

L5P: If no .e41 sidecar is found, you will be prompted to load
a reference EFI Live .bin file for E41 controller blocks.

Supported modules and file sizes:
L5P Duramax (17-19): HP Tuners = 5,898,192 bytes | EFI Live = 6,299,648 bytes
LML Duramax (15-16): HP Tuners = 4,194,304 bytes | EFI Live = 4,325,376 bytes
E86A LML (11-14): HP Tuners = 9,175,040 bytes | EFI Live = 3,276,800 bytes
T87 TCM (6L80/6L90): HP Tuners = 4,128,768 bytes | EFI Live = 4,194,304 bytes
A50 TCM (6T70/6T75): HP Tuners = 2,555,904 bytes | EFI Live = 2,621,440 bytes
T87A TCM (10L80/90): HP Tuners = 2,621,392 bytes | EFI Live = 4,202,496 bytes

E86A NOTE: Place ‘EFI Padding.bin’ (393,216 bytes) in the same folder
as this application. It is required for 11-14 E86A LML conversions.

---

CTZ CONVERSION:

• CTZ to BIN: Native CTZ file converter (no external tool needed).
  Converts EFI Live .ctz calibration files to raw .bin format.
  Supports both unlocked and locked .ctz files.
  The output .bin is in EFI Live format and can be used as a reference
  file for E41 controller blocks when converting HPT to EFI BIN.

LOCKED FILE CHECKBOX:
Check the ‘Locked File’ checkbox next to the CTZ to BIN button
before converting if your .ctz file is locked/encrypted.
If unchecked, the converter will auto-detect the file type.

How to use:
1) Check ‘Locked File’ if your .ctz is locked (optional).
2) Click ‘CTZ to BIN’ on the Convert tab.
3) Select a .ctz file to convert.
4) Choose where to save the output .bin file.

• CTZ to HPT: Converts a .ctz file to HPT format.
  Works natively without requiring an HPT file to be loaded.
  If an HPT is loaded, imports CTZ data into its segments.
  If no HPT is loaded, creates a new HPT file directly.
  For L5P/LML: Automatically saves a .e41 sidecar file alongside the HPT
  output. This sidecar preserves E41/controller block data for later
  conversion back to EFI BIN format with valid checksums.
  1) Click ‘CTZ to HPT’ on the Convert tab.
  2) Select the .ctz file to import.
  3) The CTZ is decrypted/decompressed to BIN, then converted to HPT.
  4) The HPT (and .e41 sidecar) is saved automatically.

---

SEGMENT SWAP:

• Segment Swap: Select donor and target files, choose segments, apply copy, and save swapped result.
  If prompted, re-open/analyze target to verify values before final save.

---

RECOMMENDED WORKFLOWS:

CTZ -> Edit -> EFI BIN (best for EFI Live output):
1) CTZ to HPT -> saves .hpt + .e41 sidecar
2) Open and edit the .hpt file
3) HPT to CTZ -> auto-loads .e41, saves EFI .bin with valid checksums

CTZ -> Edit -> HPT:
1) CTZ to HPT -> saves .hpt file
2) Open and edit the .hpt file
3) Save as new HPT

HPT -> EFI BIN (no CTZ source):
1) Open HPT file
2) HPT to CTZ -> prompted for reference EFI BIN (optional)
3) Saves EFI .bin file

Notes:
– Keep backup copies before any write operation.
– For Segment Swap, only swap compatible donor/target files.
– CTZ to BIN, HPT to CTZ, and CTZ to HPT all work standalone (no HPT file required).
– For locked .ctz files, check the ‘Locked File’ checkbox before clicking CTZ to BIN.
– If an HPT is loaded, CTZ to HPT imports data into its segments instead.
– If an operation fails, reopen the original file and retry with fresh output path.
