Corvette CCM Reverse Engineering Anyone?

[NomakeWan]

NomakeWan can you make an updated dump of the ccm you have. Hope thay gathered some mileage, so we can identify some stuff pretty quick, if the eeprom increase at some places.

Sure, I can do that later today. I've put plenty of miles on the car since I took those dumps.

FOund the mode5 code in the bin, but there is not much that it can do. It seems the ccm enters some loop where you can upload custom code. It still doesn`t make sense since there is no execute visible in the loop.

Also I think I spot the bit that prevents the mode5 entering. It will be esily patched if we have access to writing a custom bin.

Now the main question. What should I expect from mode 5.
