The Fusion dashboard
Upload your logger's CSV and Fusion times every corner of your lap against your best, shows you on the aerial photo of your track exactly where the time went, and tells you what to change.
Biggest loss · T9 +0.264s
The problem
Every tenth you're missing gets paid for in tyres, test days and entry fees. A lap timer tells you that you were slow. It can't tell you which corner, or what to change before the next session.
Fusion is the affordable race team
you bring with you on the day.
A real session
Not a mock-up. This is Tasman's own session at Griffith Kart Club, run through the Fusion app exactly as yours would be, laid over the real aerial photo of the circuit. Lap 26 against his best, lap 12: +0.464s slower, and every corner accounted for.
| Turn | Gap | Min km/h | What changed | |
|---|---|---|---|---|
| T1 R | +0.175 | 64 / 65 | 6 m later braking | |
| T2 L | −0.096 | 66 / 63 | +3 km/h at apex | |
| T3 R | +0.078 | 70 / 71 | No change | |
| T4 L | +0.018 | 78 / 80 | −2 km/h at apex | |
| T5 R | −0.022 | 61 / 63 | −2 km/h at apex | |
| T6 R | −0.005 | 55 / 52 | 4 m later braking | |
| T7 L | +0.078 | 49 / 48 | No change | |
| T8 R | −0.026 | 47 / 44 | +3 km/h at apex | |
| T9 L | +0.264 | 63 / 66 | −3 km/h at apex |
Lap 26 vs lap 12. Min speed is lap 26 / lap 12. Braking points are where the speed starts falling, from GPS.
Lap 12, coloured by longitudinal g: red where the kart is slowing, green where it's driving out. Touch any point in the app to read speed and RPM there.
Lap 12 (yellow, 40.416s) against lap 26 (blue, 40.880s), each drawn where the GPS put the kart. Zoom in on any corner in the app to see where the lines split.
All 26 laps. Lap 1 is the warm-up; lap 2 was a slow lap the app flags and leaves out of the averages. Best corners from every lap add up to an ideal 39.876s.

Key features
A lap timer tells you that you were slow. After every session the Fusion app tells you what to do about it: on the driving, on the kart, and against your mates. Everything below is real output from real sessions.
Fusion lines every lap up against your own best pass through each corner, finds the habits costing you time, and gives you the three changes worth the most, in plain language, with the numbers behind them.
Carry more speed through T11 ~0.17s
Your best passes were 4.0 km/h faster at the slowest point, so the grip is there. Ease off the brake earlier and let the speed roll in to the apex rather than slowing to a crawl.
Minimum speed 70.8 km/h typically, 74.8 km/h on your best passes.
Get up to speed sooner ~0.26s
Your first two timed laps were 1.30s slower than the rest. Use the out-lap to load the tyres so the first flying lap counts.
First two laps averaged 50.91s vs a typical 49.61s.
Pick a brake marker for T1 ~0.12s
Where you start slowing for T1 moves about ±10 m lap to lap. Choose a fixed reference and hit it every lap before trying to move it later.
Braking point varies ±10.4 m across 10 laps.
The logger's motion sensor shows how the chassis is behaving: whether the inside rear is lifting cleanly, whether the front is biting, whether the rear is stepping out. Fusion reads it against your setup sheet and tells you what to change, in millimetres.
This TaG's own notes said “old tyres”. Fusion worked that out from the data alone.
Low grip overall: peak cornering 1.49 g against roughly 1.8 g for this class, with smooth steering, so the tyres are probably not working.
Grip comes from the tyre being in its temperature window. Smooth driving with low cornering load points at the tyres, not the chassis.
Put any lap against any other and see the gap corner by corner: where it was won or lost, the speeds through each one, and whether it was the braking, the apex or the drive out.
| Turn | Gap | Min km/h | What changed | |
|---|---|---|---|---|
| T1 L | −0.027 | 61 / 61 | 24 m earlier braking | |
| T2 R | −0.065 | 70 / 70 | No change | |
| T3 L | +0.148 | 67 / 73 | −6 km/h at apex | |
| T4 R | +0.076 | 64 / 65 | −5 km/h on entry | |
| T7 R | +0.100 | 69 / 71 | −2 km/h at apex | |
| T11 R | +0.235 | 68 / 75 | −7 km/h at apex |
Six of 11 corners shown. Min speed is lap 10 / lap 9. Ideal lap from the session's best corners: 48.903s.
How it works
In AiM Race Studio, open the session from your AiM or MyChron and export it as a CSV. VBOX files and GPS app CSVs work too.
About a minuteDrop the file on the dashboard. Laps are found from your GPS line, at any track, with no beacon or setup.
SecondsSee every corner against your best, where you braked and turned in differently, and the coach's fixes ranked by the time they're worth.

Get to know the company
Fusion is the affordable race team you bring with you on the day. Tasman Reedie · Founder & engineer
Tasman Reedie knows what it costs to chase a lap time. He grew up racing karts and became a race winner, but every result came at a price: hours of practice, sets of tyres and money spent on test days that often taught him very little. To keep racing, he left school at 15 and went to work.
He once spent $800 on a lap timer, hoping it would help him find speed. All it told him was that he was slow. It offered no setup changes and no driving advice, so he had no way of knowing what to do differently on the next lap.
That frustration shaped everything that followed. Tasman trained as a heavy vehicle diesel mechanic, rebuilding engines, gearboxes and hybrid systems, and then went back to study. He completed an honours degree in Electrical and Electronics Engineering at the University of Wollongong, and along the way designed embedded firmware, IoT devices and GPS systems. He set out to become the engineer who could build the tool he never had.
Fusion is that tool. Big teams give their drivers a huge head start. Drivers pay thousands of dollars to join them, and on day one they are handed thousands of laps of data showing how to set up the kart for the track and exactly where to brake, turn in and get back on the throttle. Drivers without that support are left guessing, and a list of tips downloaded after the test day is no use when the session is already over.
Tasman designed and coded Fusion himself, pairing an affordable data logger with an app that gives instant feedback. After a single session, drivers get clear insights they can act on straight away, while they're still at the track and it still matters.
Fusion was built to make racing more affordable for drivers on a budget, and that will always be its purpose. In Tasman's words, Fusion is the affordable race team you bring with you on the day.
