VIN Fixer
Convert a 17-character VIN between the three formats diesel calibration software uses — plain VIN text, Calterm ASCII hex, and HP Tuners decimal. Paste any format, hit Convert, and copy the output you need.
BIN → HEX
Upload any binary ECM calibration file (.bin) and download a ready-to-use Intel HEX file (.hex). Drop it straight onto the EFI Live icon to load — no extra software, no command line, and nothing is sent to any server.
VIN Decoder
Paste a 17-character VIN for a full breakdown — year, make, model, trim, engine, fuel type, transmission, GVWR and plant. Uses the free NHTSA government database when you're online, with a built-in offline fallback.
VIN / SKIM
Load a good SOURCE .bin and a TARGET .bin. The tool reads the VIN and SKIM key from the source and writes them to the correct fixed CMF2450 AISIN addresses in the target — even if those fields are blank. Download the patched file when done.
Chrysler / Dodge OS Match
Type any part number, a calibration / OS name (e.g. "2015 LX 3.6L"), or a make / model (e.g. "GRAND CHEROKEE", "RAM 3500"). Pick a match to see the vehicle, the current superseding part number, and every older part it replaces — all cross-compatible — plus any related TSBs and recalls. 21,000+ calibrations, all in your browser.

How it works
- Load a known-good SOURCE .bin (has the correct VIN + SKIM key).
- Load the TARGET .bin you want to patch.
- Choose whether to copy the VIN, the SKIM key, or both.
- Click Transfer — the patched .bin downloads automatically.
Values are written to the fixed CMF2450 AISIN addresses shown above — even if the target fields are blank. Everything runs in your browser; nothing is uploaded.
