HPT to BIN Converter - ECU Data Calculator Utility Tool 0.1

• Does the converter perform a straight raw data dump, or does it attempt any checksum recalculations on the exported .bin file?
• What is the expected behavior when encountering tunerlocked or otherwise secured .hpt files? I assume these cannot be converted, but confirmation would be appreciated.

0x80020000 - 0x80400000.bin not saved!
Not replaced address:
0x80020000 - 0x80400000 not replaced because address is out of scope 0x0 - 0x114202

• The .hpt was saved as a calibration-only read (not a full flash/full ROM dump). HP Tuners often stores just the cal segment, so higher address ranges like 0x80020000+ are simply not present.
• The ECU platform expects a multi-segment dump (common on newer GM E38/E67/E92/T87 controllers where calibration and OS live in separate flash blocks), but your .hpt only captured one segment.

1. Vehicle — year, make, model, engine
2. ECU type — E38, E67, E92, T87, P59, etc.
3. How the .hpt was created — was it a full read via VCM Scanner, or just a calibration save / tune file from VCM Editor?
4. File size of the .hpt

The error in your screenshot is clear:

Code:

0x80020000 - 0x80400000.bin not saved!
Not replaced address:
0x80020000 - 0x80400000 not replaced because address is out of scope 0x0 - 0x114202

The tool is telling you that the .hpt file you loaded only contains calibration data in the address range 0x0 – 0x114202 (roughly ~1.1 MB), but it's trying to export a segment mapped to 0x80020000 – 0x80400000 — which is a completely different memory region that doesn't exist in your file.

This typically happens when:

• The .hpt was saved as a calibration-only read (not a full flash/full ROM dump). HP Tuners often stores just the cal segment, so higher address ranges like 0x80020000+ are simply not present.
• The ECU platform expects a multi-segment dump (common on newer GM E38/E67/E92/T87 controllers where calibration and OS live in separate flash blocks), but your .hpt only captured one segment.

To troubleshoot, please provide:

1. Vehicle — year, make, model, engine
2. ECU type — E38, E67, E92, T87, P59, etc.
3. How the .hpt was created — was it a full read via VCM Scanner, or just a calibration save / tune file from VCM Editor?
4. File size of the .hpt

If you only have a calibration-only .hpt, the converter can only export what's inside it — you won't get a full ROM .bin from a partial cal save. You would need to go back to HP Tuners and do a full flash read of the ECU to capture all segments including the 0x80020000+ range.
