Built for the 86 Twins — GR86 & BRZ

See what your car was doing. Not just your lap time.

Drop in a RaceChrono export and get a synchronized GPS track map, telemetry charts, lap comparison, and oil-pressure health analysis grounded in the FA24 factory service manual — all running in your browser.

Track day drivers logging with RaceChrono

If you're running a GR86 or BRZ on track with a RaceChrono CSV export in hand, this reads it — no upload to a third party, no account, no waiting.

Chasing lap time

Compare laps against your fastest with a distance-aligned delta chart — see exactly where you gained or lost time, corner by corner.

Watching the engine

Oil pressure, oil temp, RPM, and G-load in one view — with a detector built to tell real sustained drops apart from sensor noise.

Learning the track

Click anywhere on the map or any chart and jump straight to that exact moment — speed, G-force, and engine data all in sync.

Every channel your export carries

RaceChrono's CSV v3 format brings in GPS, IMU, and CAN-bus channels together — the analyzer parses all of it and keeps the map, charts, and cursor in sync.

GPS track map

Speed-colored racing line, click-to-locate, ghost overlay of your fastest lap.

Lap delta comparison

Time gained/lost vs. any reference lap, plotted against distance, not time.

Engine RPM & throttle

Full-resolution traces synced to the map cursor.

Lateral & longitudinal G

Cornering and braking/acceleration loads, peak and average per lap.

Oil pressure & temp

RPM-relative health analysis — see the full write-up below.

Tire pressures

All four corners, peak/min per session, plotted on a car diagram.

Oil monitoring grounded in the factory spec, not a guess

The expected-pressure curve is built from the FA24 factory service manual's own minimum-pressure points, not an arbitrary threshold — and it only flags a drop once it's sustained long enough to be a real mechanical event.

  • RPM-relative expected minimum, interpolated from factory spec points (idle → redline)
  • Sustained-drop filtering — momentary sensor noise doesn't get flagged as an event
  • Severity tiers from a harmless blip to a genuine, sustained low-pressure event
  • Correlated against lateral G, since oil starvation under hard cornering is a known FA24 pattern
BlipBelow spec, momentary
CautionMeaningfully under spec
RiskyFar under spec for RPM
DangerBelow 20 psi
CriticalSustained below 20 psi

What this has actually been tested against

Not a generic "should work with anything" claim — this is the exact data path it's built and verified on.

Save sessions, share a lap, compare with a friend

Soon

Cloud-saved sessions and shareable links are in progress — sign in, save a session, and hand someone a link that opens straight into this same analyzer, no account required to view it. The analyzer above already works fully today without any of that; this is additive, not a gate.
