The BIN file you uploaded is a 4MB Continental GPEC2A firmware image. To convert it to HPT format, you'll need to use the BIN to HPT conversion feature in the HPT File Editor 2026 Hoppers tool that I linked above.
Here's the workflow:
Download and extract the HPT File Editor 2026 Hoppers package from the resource thread
Complete the activation process (post your activation.req file in that thread with your chosen license name)
Open the tool and navigate to the CONVERT tab
Select BIN to HPT
Load your DodgeCharger2015...BootNR.bin file
The tool will build an HPT-compatible file from the BIN image
The tool can extract VIN, OS and segment information during the conversion process. Since this is a Continental GPEC2A controller, make sure the resulting HPT file shows the correct Main OS and Interface ID after conversion.
Keep a backup of the original BIN before working with the converted file.
That message means the tool needs an existing HPT file open as a base before it can import your BIN — it uses the HPT's segment structure and table definitions as a template, since a raw BIN doesn't carry that metadata on its own.
The correct order is:
Open a base HPT file for the same platform first (GPEC2A / Pentastar 3.6) — File > Open HPT
Once that file is loaded, go back to Convert > BIN to HPT
Point it at your BIN and it will overlay the calibration data from the BIN into the open HPT structure
If you don't have a base HPT for this platform, check the resource thread Bin linked earlier — there's usually a stock/base HPT included with the package, or posted in that thread. Do you have one available, or is that what's missing?
That's the most common sticking point with this workflow — the package doesn't always ship with base HPTs for every platform.
A few places to look:
Check the resource thread Bin linked earlier in this thread. Sometimes base/stock HPTs for common platforms are posted there as attachments or in the replies.
Search the forum for GPEC2A stock HPT or GPEC2A base tune — there are usually a few threads where members have shared them for the Pentastar 3.6.
If you can't find one, post a request in the appropriate subforum with your exact vehicle details (2015 Dodge Charger 3.6 GPEC2A) and someone will likely have one to share.
If you do find a base HPT from another source, just make sure it matches your OS version before using it as a template — mixing OS versions can cause table mismatches after the BIN overlay. Once you have the right base HPT open, the conversion should go through cleanly.
