Learn about how to analyze lap times in F125

Updated October 12, 2025

If you’re new to F1 25 and stuck trying to figure out how to analyze lap times in F125, you’re not alone. It’s frustrating when the clock won’t budge and you’re unsure where the time is going. That’s normal—F1 25 rewards precision, and without a clear method, it’s hard to spot where you’re losing out. This guide gives you a simple, step‑by‑step process to find your biggest time losses and fix them.

Quick Answer

Use Time Trial with a personal best ghost and the live delta enabled. Set a clean baseline lap, then compare against your ghost and a slightly faster leaderboard/rival ghost. Note exactly where the delta goes red, review the replay/telemetry for those corners, change one thing at a time (brake point, minimum speed, throttle timing), and re-test in 2–4 lap stints.

Why how to analyze lap times in F125 Feels So Hard at First

The game hides time in small places—brake release, rotation, and throttle timing—not just obvious mistakes.
Conditions (tyres, ERS, line, assists) must be consistent; if they aren’t, comparisons are noisy and misleading.

By the end of this guide, you’ll know exactly how to set up comparisons, read your delta/ghosts, isolate problem corners, and turn that into real lap time.

What how to analyze lap times in F125 Actually Means in F1 25

Lap Time: Your full lap duration.
Sector Times (S1/S2/S3): Coarse splits that show which third of the lap needs work.
Live Delta (+/−): Real-time gain/loss versus a reference (usually your PB). Green/negative = faster; red/positive = slower.
Ghost Car: A transparent car showing a saved lap (your PB or another player). Follow it to copy pace and references.
Micro-sectors (mini-splits): Small rolling comparisons in the delta bar that show exactly where time changes.
Valid vs. Invalid: Invalid laps don’t set PBs or save ghosts—always chase valid laps for analysis.
Consistency vs. Peak Pace: Improving average sector pace (repeatability) often beats a single “hero” lap.

Before You Start (Prerequisites)

Hardware: Controller or wheel both work. Wheel + pedals makes throttle/brake analysis easier, but not required.
Mode: Time Trial (TT) for clean, repeatable comparisons. Use Practice/Qualifying later for race prep.
Patch/Build: Latest F1 25 update recommended.
In‑game menus you’ll use:
- Home > Solo > Time Trial
- Settings > On-Screen Display (OSD): enable Delta Time, Lap Data, and Track Map (With Sectors).
- Time Trial Options: configure Ghosts (Personal Best, Rival/Leaderboard).
- Pause > Replay to review laps.
- Optional: Settings > Telemetry/UDP for external dashboards (if you use SimHub/telemetry tools).

Step-by-Step: How to Fix / Improve how to analyze lap times in F125

Enter Time Trial
- Go to Solo > Time Trial. Pick the track you want to learn and the current F1 car.
- Success looks like: a simple TT screen with weather fixed and equal conditions every lap.
Turn on the right HUD info
- Open Settings > On-Screen Display:
  - Delta Time: On
  - Lap Data: On
  - Track Map: Full (With Sectors)
  - Optional: Racing Line if you’re learning; turn it off later for precision.
- You should now see a live +/− delta on-track and sector split colors.
Set up your ghosts
- In the Time Trial options, enable Personal Best Ghost.
- Add a Rival/Leaderboard Ghost that’s about 0.5–1.5s faster than you (not an alien lap).
- If the ghost is distracting, reduce its visibility or toggle it only when comparing.
- Success looks like: a transparent car appears when you’re on a flying lap; the delta updates live.
Create a clean baseline lap
- Do an out-lap to warm tyres, then a valid push lap. Don’t chase the absolute limit—just clean and consistent.
- If invalid, lift and try again. Time Trial resets battery and DRS logic lap-to-lap, so conditions stay comparable.
- Success looks like: your lap saves as Personal Best with sectors shown.
Identify where you’re losing time (coarse)
- Run 2–3 laps with your PB ghost and watch the delta.
- Note exactly where the delta goes red: “Turn 1 exit,” “Turn 6 entry,” “Turn 10 braking.”
- Use sector times to pick the worst sector; start there.
Zoom in with replay and overlays
- Pause after a lap > Replay.
- Enable the replay HUD that shows speed/gear/throttle/brake (look for a telemetry overlay if available).
- For each problem corner, ask:
  - Did I brake too late (missed apex) or too early (under-used grip)?
  - What’s my minimum speed vs. the ghost’s apparent arc?
  - How smooth is my brake release? Am I carrying rotation into the apex?
  - When do I go full throttle? Early but with wheelspin is slower than slightly later but clean.
Make a simple action plan (top 3 corners)
- Write down 3 changes, e.g.:
  - T1: Brake at the 100 board instead of the 75; trail off earlier to hit apex.
  - T6: Downshift one extra gear for rotation; target +2–3 km/h higher minimum speed.
  - T10: Delay throttle 0.2s to avoid traction loss; straighten steering before 100% throttle.
Test changes in short stints
- Do 2–4 push laps, then stop and compare. Short stints keep tyres consistent and your focus sharp.
- Watch the delta through just the corners you’re testing. Ignore the rest for now.
- Success looks like: those corners flip the delta from red to green, even if the whole lap isn’t perfect yet.
Compare against a faster ghost (optional)
- Switch to a Rival/Leaderboard ghost slightly faster than your new PB.
- Learn new references: earlier lift, later apex, different gear, earlier rotation, or straighter exits.
- Copy one detail at a time. Don’t try to mirror their entire lap on the first attempt.
Validate with consistency

Aim for 3 clean laps within 0.2–0.4s of each other. This shows the change is real, not a fluke.
If your best lap improved but spread widened, focus on repeatable braking points and throttle discipline.

Optional: use external telemetry

If you have a telemetry app:
- Go to Settings > Telemetry (UDP) and turn it On. Match the IP/port your app expects.
- Compare min corner speeds, throttle/brake traces, and speed at corner entry/exit between laps.
Only chase telemetry after you’ve done steps 1–10; it adds detail but can overwhelm early on.

Lock it in

Once you’ve found time, save a Replay of your best lap and keep the PB ghost active for future sessions.
Success looks like: you can predict where the delta will go green before you reach those corners.

Common Mistakes and Myths About how to analyze lap times in F125

Chasing setups first: A great setup won’t fix bad brake release or poor exits. Fix driving fundamentals, then fine‑tune setup.
Analyzing invalid laps: If track limits are broken, comparisons are meaningless. Use valid laps.
Copying aliens: A ghost 2–4 seconds faster hides the “why.” Pick a ghost just slightly faster than you.
Overfitting one hero lap: If you can’t repeat it, it’s not a real gain. Prioritize consistency.
Ignoring exits: Most lap time is won on corner exit. Sacrifice a touch of entry speed for a straighter, earlier throttle.

Troubleshooting and “What If It Still Feels Wrong?”

Delta not showing
- Likely cause: OSD option disabled.
- Fix: Settings > On-Screen Display > Delta Time: On. Also ensure Lap Data: On.
Ghost doesn’t appear
- Likely cause: No valid PB or ghost visibility toggled off.
- Fix: Set a valid lap first. Check Time Trial Ghost settings and your bound “Toggle Ghost” control in Settings > Controls.
PB won’t update
- Likely cause: Lap invalidated or assists/conditions changed mid‑session.
- Fix: Keep laps valid. In TT, conditions are fixed; if you changed assists significantly, re-run a clean lap.
Replay has no telemetry overlay
- Likely cause: Different replay HUD mode.
- Fix: Cycle HUD overlays during replay (check on-screen prompt or Controls > Replay bindings).
External telemetry not working
- Likely cause: UDP off, wrong port, or PC/console network mismatch.
- Fix: Settings > Telemetry (UDP): On, match IP/Port/Protocol in your app, ensure both devices are on the same network.
- Note: Tool support can change with patches; check your tool’s F1 25 compatibility.
I’m faster in sector 1 but slower overall
- Likely cause: Over‑pushing early overheats tyres or ruins exits later.
- Fix: Drive at 9.5/10ths early. Guard tyre temps and prioritize exits in the longest straights.
Should I max ERS/Overtake everywhere?
- No. Mode behavior can vary by game mode, but spamming Overtake in traction zones can cause wheelspin and slower exits. In TT, battery refreshes lap-to-lap—compare like for like, focusing on clean exits.

Pro Tips Once You’re Comfortable

Name corners by number and build a corner log: brake marker, gear, min speed, throttle point, common mistake.
Use the Track Map with sectors and mentally split each sector into 2–3 key corners.
If the ghost distracts you, turn it off on the approach and toggle it back on after corner exit to check gains.
Do “focus laps”: only work on two corners per stint. Everything else at 90% to keep temps/consistency.
When you’re within ~0.3s of your target, gains usually come from smoother brake release and better car rotation, not later braking.

How to Know It’s Working (Definition of Done)

You can point to the exact 2–3 corners that cost most time and say why (entry, apex, or exit).
Your delta in those corners is now green more often than red.
You can produce 3 consecutive valid laps within 0.2–0.4s.
Your fastest lap improved, and your average sector times are quicker.
Your PB ghost and delta are visible, and you can toggle a faster rival ghost on demand.
