Looks like the JB4 autotuning supports E85 blended with 91/93 (straight E85 not recommended).

I'm glad I sold my N54 E90...too much temptation, power corrupts!

The N20 is saving me from myself.

I wonder which features will make their way into the N20/N26 Stage 2 (JB4) tune?

N55 Stage2 (JB4) Upgrade Kit

Upgrades your current Stage1 control box to the latest Stage2 JB4 processor. Featuring 5x the processing power, 2x the memory, more robust signal conditioning, and of course integrated CAN. The CAN module allows the Stage2 to communicate with your vehicle like never before. New features are too numerous to fully list but include code reading/deleting, optional in dash boost, timing, air/fuel, shift light, and IAT gauges, autotuning, a buttery smooth new CAN based integrated boost control system, steering wheel controls, built in downpipe fix, hot/cold oil temperature protection, progressive methanol integration, water pump remapping, and much more to come with simple firmware updates.
