A MyChron 5 session open in Purple Sector: the Queensland Raceway National map with its six turns and the gap at each, beside the list of laps.
Shown: a real MyChron 5 session at Queensland Raceway National. A file from any logger Purple Sector reads opens in the same view.

How do I get the session file from Alfano ADA?

Bring: the session exported as CSV from ADA

On a computer

  1. In ADA for Windows, download the session by the A4540 USB cable or the A4550 wireless dongle (neither comes in the box).
  2. Export the session as CSV.
  3. Open that file here, as ADA wrote it.

On a phone

  1. On the logger, turn on sharing (on an Alfano 7, the centre right button).
  2. In the ADA app, download the session over Bluetooth.
  3. Export the session as CSV, then choose “Save to Files” (iPhone) or Downloads (Android).
  4. Back here, open your lap file and pick it from “Recents” (iPhone) or Downloads (Android).

Watch out: Don’t open and re-save the CSV in Excel. It can change the separators.

What else should I know about the file?

Limits to know
  • ADA covers the Alfano 7, Alfano 6, PRO III EVO and ADSGPS.
  • The export does not say whether speed is in km/h or mph, or which G-force axis is which, so both are matched to the GPS track: Gf.
  • X and Gf.
  • Y are used as the kart’s g only where they follow it, and shown as worked out rather than measured.
  • The GPS rate is read from the file too.
  • Temperature and rear-speed channels keep their Alfano names.
Is speed in km/h or mph?

The export does not say, so Purple Sector matches it to the GPS track. G-force, temperature and rear-speed channels keep their Alfano names.

What do I see once the file opens?

Lap 6 picked against lap 1: the gap to lap 1 at every turn on the map, T3 the largest at +0.87 s.
The gap to your best at every turn.
The map closed on T3, marked +0.87 s, with both laps' lines through the corner.
The corner that cost time, with both lines.
The AI Coach card for T3, +0.87 s: “Turn in about 2 m wider into T3 and get back on the throttle about 3 m sooner out of it.”
One card for that corner, with its numbers.
