I have been working on this for a while now .
I have designed a cable and software that will :
Read full bin in bin format
Read cal in bin format
Write the calibration section direct from bin file

Only remaining issue to sort out is writing a full bin file so os can be changed ,just need to tweek the bootloader file a bit more when i get time .

No licences are required giving freedom to flash as many pcms as you wish

Watch this space.

Nice work, look forward to the release.

awesome, look forward to it.

Interesting indeed. May put a few noses out of joint with the software outfits that do require licences...

Anyone making custom OS? There's one company doing it and aren't cheap they are marketing it as a replacement for Delco.

Efilive and Hptuner both have custom o/systems for ls1 pcms ,they are only really needed if you plan to run mafless and still have both hi/lo octane spark maps operating, or if your wish to run a boosted setup.
If you run a std os mafless you will only have the lo octane spark map operating.

thats true, but to get both maps going when mafless its just one simple patch in the right place.

Where in the code does the patch need applying ,cal section or operating code section.

I'd say it would be in the operating code

depends on the OS, but yes, in the operating system code.
