Features · v2.4.7

A workshop tool. Wired like one.

Every feature is here because a tuner asked for it — on the bench or at the OBD port. No growth-hacked dashboards. No AI-suggested fuel maps.

Map coverage

Every map the factory writes, exposed.

Grouped exactly like the workshop manuals — fuel and ignition first, then everything else, then the unsexy settings.

Walk-through

From bench to flash, in one window.

Identify the ECU, pull the ROM, edit it, diff every cell before you flash. Every step lives in the same window — no file shuffling, no second tools, no cloud round-trip per keystroke.

STEP · 01

Identify the bike on the wire

Plug into the OBD-II port or your bench harness, hit Identify. The app reads the part number, the chip family, and the bike's market off the ECU itself. The Operations panel only shows actions this specific ECU will accept — no buttons that aren't real.

STEP · 02

Read it like a workshop manual

Every map opens as a colour-graded heatmap. Switch between raw values, %trim, or Δ delta. Cells run red where they are high, blue where they are low — the pattern reads first, the numbers read second.

STEP · 03

Or as a surface, if that is how you read them

Same data, rotated. The 3D view exposes ridges and dips that flatten out in a table — useful for locating peaks and troughs at a glance.

STEP · 04

Every edit is accountable

Switch the colour mode to Delta. Cells you have touched light up; cells you haven't stay flat. If your change isn't visible in this view, it isn't going on the bike.
