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
No account needed — runs in your browser.
Open the stock .hpt on the left (truck VIN + SKIM) and the donor .hpt on the right. Writes the donor’s existing VIN copies plus SKIM, then saves *_ecmswap.hpt. Same 22–24 Cummins path as Bulk to Bin.
Equipment Existing Look Up
FCA factory equipment for Dodge, Chrysler, Jeep, Ram, and Fiat. Paste a VIN and the page reads the equipment listing: 68RFE or Aisin, 2500 through 5500, pickup or chassis cab, axle ratio, DRW or SRW, and the Cummins engine.
GM Cal ID Look Up 2017-2023 L5P
Chevrolet and GMC. Paste a VIN for the K20 calibration history: Main Operating System, System, Fuel system, Speedometer, Engine diagnostic, and Engine Operation. The newest part number is first in each list.
OS Match
Type a Chrysler part number, a Cummins IA number, a Ford strategy, or a truck. Pick a match to see the vehicle and every compatible part or software version. Chrysler, Ford, GM, RAM, and WinOLS, all in your browser.

Enter a 17-character VIN to begin.
The decoded breakdown will appear here — year, make, model, engine, transmission, fuel type, plant, and more.
No file loaded
Load the stock / truck file.
Same as Bulk to Bin: open the stock .hpt (or .bin), then the donor .hpt. Writes only the donor’s existing VIN copies + SKIM, then downloads *_ecmswap.hpt. Your originals are not overwritten.
No file loaded
Load the donor / tune file.
VIN copies sit on the first VIN: +0 · +0x12 · +0x50E · +0x10D58 | SKIM is 7 bytes at first VIN + 0x28 (High 4 / Low 2, last byte usually 01). Works on 16 MB @0 and EFILive slim boot (0x1098 / 0x10A8).
Load stock and donor .hpt files (BIN still works), then click Write ECM swap.Download ECM swap file
How it works
- Load the stock .hpt from the truck (correct VIN + SKIM).
- Load the donor .hpt (ECM / tune that should receive that identity).
- HPT is decoded to flash, VIN+SKIM are written, then the donor casing is rebuilt — same as Bulk to Bin.
- Click Write ECM swap — downloads
*_ecmswap.hpt. A .bin donor still writes*_ecmswap.bin.
This is the Bulk to Bin ECM Swap 22–24 path in the browser (modern v12+ HPT/RTD). The full desktop suite is Bulk to Bin — $1,000.
