The Evolution Engine
Harley's air-cooled 883 cc vee has been in production since the nineteen eighties. Its injection was added late and mapped conservatively for emissions.
Interpolation Between Cells
The unit does not jump from one value to the next. It blends between neighbouring cells, which is why a smooth map produces a smooth engine and a spiky one does not.
Two Owners, One Bike
The map lives in the unit, not in the rider. Anybody who rides the motorcycle gets whatever was last written, which is worth remembering on a shared machine.
Reversible Means Reversible
Unplug the unit, mate the original connectors and every trace is gone. Nothing was written to the motorcycle and nothing needs restoring.
Two Silencers, Two Files
Switching exhausts means switching maps. Both live on the laptop and writing either takes under a minute, which is the flexibility the preset module cannot offer.
Write, Ride, Repeat
That is the whole method. Change a region, ride the same road at the same load, read the mixture and decide whether the change helped.
If Something Feels Wrong
Write the empty map back and ride the same road. Ten minutes settles whether the unit is responsible, which is a diagnostic luxury a reflash does not give.
Load Sites and Breakpoints
The map's axes are divided at fixed points chosen for the engine. Knowing where those breakpoints fall tells the mapper which cells a given road speed actually uses.
Two Configurations, Two Files
Road silencer and race can, pump petrol and race fuel, summer and winter. Each combination deserves its own map, and switching between them takes less than a minute once they exist.
