Unless Jake does something, I am not planning realtime on N54, just the Bosch based DMEs.

Level 10 expert only visibility for power users I am about to confuse the crap out of most:
Ethanol content sensor frequency output -> microcontroller -> ethanol content (0.1% scaling so 1000=100% ethanol) -> CAN bus -> gateway > DME -> store result in memory backed up by EEPROM after driving -> this table to convert to ethanol %.
The flexibility here is to change the pointer to something else and scale the "ethanol" input how you like based on any variable you like. Originally this was going to be a voltage input from an ethanol content analyzer, but now it is from a CAN input. It could be a constant value that can be altered by flash or realtime tuning, a value backed up in EEPROM after driving as a map switch/blend value, some status from a water/methanol/port injection system...
Similar concept expandable to other features.

I don't talk much about the encryption stuff, but it is novel in the automotive aftermarket. It has been running flawlessly since September on my wife's N55 though.
There are other firsts here too: using CAN bus for custom inputs on an OEM ECU, and being able to freely realtime tune any table/value rather than just those the developer has curated/selected is also new to the automotive aftermarket without a physical emulation device in the ECU.
I hope the final quality and usefulness reflect the effort and innovations involved.
It is orders of magnitude more ambitious than the GT-R work I did for Cobb. The market enjoyed that. I know burbles will outsell realtime tuning, but maybe the most popular aspect of it will be realtime burble adjustment. I will try to suppress my feelings on that as long as my cat is fed.
