Your kart fades near the end of a session. Now you can see exactly why

Watch your lap times across a long run and you'll feel it before you can prove it. The first few laps are sharp. Then, somewhere past half distance, the kart stops finding the same time even though you're driving just as hard. Tenths leak away and you can't quite say where.

We built something to show you where.

On the results page, the Engine & Chassis Performance panel now draws a lap-by-lap graph of how your kart really performed, from your first flying lap to your last. Not one average for the whole session. Every lap, plotted, so the trend jumps straight out at you.

What the graph actually shows

Two stories, side by side. One line follows your engine pull, how hard the kart drives off the corners for the grip it had to work with. The other follows your grip baseline, which is really your tyres and the track surface doing the talking. Peak braking and peak cornering load ride along on there too.

Flat, high lines across the whole run mean you had a good day. Lines that sag toward the end? That sag is your lost time, made visible.

When it's the engine

Say your grip line holds steady but your pull line drops away after lap eight. That's not you fading. That's power fading, and it's usually heat. An engine that's heat-soaking, or a mixture drifting rich as everything gets hot. Now you can see the exact lap it started, carry that back to the tent, and do something about it before the next run instead of after the meeting.

When it's grip

The other shape is the common one. Pull holds, but the grip baseline slides down lap after lap. Tyres going off, or pressures creeping past their sweet spot as the run goes on. This is the read that tells you to drop a few tenths of a psi next time out, or to send your quick laps in early before the rears give up on you.

And sometimes both lines fall together. That's usually the track itself losing grip on the whole field, and the graph stops you blaming your kart for something everyone out there is fighting.

Turning a hunch into a plan

Before, "it went off near the end" was a feeling you carried to the setup sheet and half-guessed at. Now it's a shape on a screen with a lap number attached to it. Pressures, gearing, when you go for the time, even whether that engine wants a proper look, all of it gets easier once you can see which one was actually costing you.

Every lap on that graph comes off your own footage, timed and verified the same way, so the trend you're reading is the real thing and not a stopwatch guess.

Try it on your next session

You get one free analysis every month on Race Ninja, no card needed, so reading your own fade costs you nothing. Send a session up, let the laps time themselves, then open the results. The performance graph is sitting right there on the overview. See where your kart really dropped off, go and fix it, and watch what that does to your place on the leaderboards.
