Remapping engines gets you more power, efficiency, top speed, blah blah blah. Fiddling with Di2 gets you... ?
Mad props. But also, the e-tube program is a bit limited; I'm sure there's a small number of folks who bump up against those limits. Also, it would be pretty sweet to have adjustment presets for different wheels which don't have the cogs in exactly the same place, or even a different number of them.
Remapping car/motorcycle engines is common, yet strangely nobody has hacked di2.
It surely can’t be that difficult for the right people?
