SprintCar Pro Help
SPRINTCAR PRO USER MANUAL
SprintCar Pro is your sprint car crew chief notebook: cars, tracks, setups, weather, inventory, engines, telemetry, accounting, and team access in one place.
What SprintCar Pro Does
SprintCar Pro helps your team remember every change, learn what worked, and make a better decision next time. The value comes from connecting the car, track, conditions, setup, driver feedback, change, and result instead of keeping those details scattered across paper notes and memory.
Remember every change
Save the setup, conditions, driver feel, and notes for each meaningful session.
Learn what worked
Look back at the same car and track instead of starting from a blank page every night.
Decide with context
Use history, weather, inventory, engine notes, and advisor suggestions to support the crew chief's call.
START HERE - YOUR FIRST 10 MINUTES
Use this quick lap through the app before race night. You do not need every optional field filled out to get value; start with the information your crew already uses.
- Step 1 - Add your car. Open Cars and enter the essentials: car name/number, engine class, chassis brand, rear end ratio, usual gear, and baseline notes. Save the car.
- Step 2 - Add your track. Open Tracks, create or select the track, and save the track name, location, length, surface, usual condition, and cushion notes.
- Step 3 - Create your baseline setup. Open Setups, choose the car and track, pick the session type, enter the important tire, stagger, gear, wing, chassis, engine, and fuel notes, then save.
- Step 4 - Record the conditions. Save the session, track condition, cushion, and weather details that matter for the night.
- Step 5 - Record driver feedback. Use the supported driver-feel language: tight entry, tight center, tight off, loose entry, loose center, loose off, lacks forward bite, will not rotate, or too free on throttle.
- Step 6 - Record what you changed. Put every meaningful adjustment in the setup notes before the next session.
- Step 7 - Record the result. Note whether the car improved, got worse, or showed no meaningful change. Use finish position and detailed notes for the result.
- Step 8 - Compare next time. The next time you return to the same car, track, or condition, use the saved history to make a better-informed call.
Race-Night Workflow
How to Use SprintCar Pro at the Track
Before hot laps
Load the car and track, check weather, confirm the active engine, and create a starting setup. Record tire pressures, stagger, gear, wing, fuel load, and track condition.
After each session
Save the current setup, then use New setup for the next session. Record the session type, starting/finishing position, driver feel, track changes, and any chassis or tune changes.
After the night
Export telemetry if used, update inventory needs, post expenses or sponsor activity, and export a vault backup.
Cars
Use Cars as the garage list. Renaming a car keeps existing setup records linked to that car.
- Save car name, number, chassis brand, engine class, engine spec, manufacturer profile, package label, rear end ratio, common quick-change gear, safe RPM limit, and notes.
- Use the installed inventory summary to see engines and parts assigned to that car.
- Assign parts from Inventory by editing a part and choosing the car in the assignment field.
- Deleting a car removes it from the car list; existing setup records stay saved.

Tracks
Use Tracks to keep the surface and geometry details that shape setup decisions.
- Add or update track name, location, length, surface, banking, corner radius, dirt type, cushion description, typical condition, key notes, and detailed notes.
- Use search and country/state filters to find a saved track quickly.
- Track packs can load common Canada/USA and Australia/New Zealand tracks. Running a pack again skips duplicates.
- Radius, banking, dirt, and cushion notes help the advisor make more useful recommendations.
Setups
Setups are the race notebook. Save one setup per meaningful session so you can compare what changed and what the driver felt.
Session Details
Record date, session name, session type, starting position, finishing position, car, track, track condition, cushion position/size, weather, fuel load, gear, target RPM, engine notes, and driver feedback.
Chassis Details
Record tire pressures, rear tire diameter, stagger, blocks, torsion bars, shocks, LR clamp/birdcage, wheelbase/axle lead, ladder settings, brake bias, wheel offsets, front track width, wing angle/position, and driver weight.
- Save setup stores the current session.
- New setup clears the editor for the next session.
- Use detailed notes to record the change and the result when the app does not have a separate result field for that item.
- Print setup sheet creates a crew-friendly sheet. Use the 1-page Race Day option when you need a compact printout.
- Apply recommended chassis fills a recommended baseline when one is available. Review it before saving.

Crew Chief Advisor
The Crew Chief Advisor turns a driver complaint and track condition into setup ideas. It is strongest when the car, track, setup, weather, fuel, wing, cushion, and driver feel fields are filled in.
- Open a saved setup or fill the current setup.
- Choose the driver complaint, such as tight entry, loose off, lacks forward bite, hops, will not rotate, too much wing drag, needs side bite, or track is slick.
- Choose track grip and phase affected: entry, center, exit, whole corner, straightaway, or starts/restarts.
- Add the driver note in plain language.
- Click Recommend Changes.
- Read the recommendation, expected result, caution, and related parts. Use Add to Setup Notes when a suggestion is worth keeping with the session.
Weather
Weather helps you track air, density altitude, radar, and the forecast window around your race program.
- Use Track, city, or address to search for the race location, or click Use my location when your browser permits GPS.
- Review temperature, humidity, altimeter/pressure, wind, precipitation chance, density altitude, and elevation.
- Use the live radar panel to watch incoming weather.
- Use manual override fields when the track weather station or your pit readings are more accurate than the forecast.
- Use the hourly session window to plan for qualifying, heats, mains, and track prep changes.

Inventory
Inventory keeps parts, quantities, locations, car assignments, and shopping needs organized.
- Filter by category, subcategory, engine, location, car assignment, or search text.
- Common categories include suspension, engine, driveline, wheels and tires, brakes, safety, fuel system, electrical/ignition, tools and shop, and other.
- Save part name, part number, brand, quantity on hand, bin/location, needed quantity, preferred supplier, and notes.
- Assign parts to a car when they live with a specific chassis package.
- Use Add to shopping list for items you need to buy soon.

Engines
Use Engines to keep build, tune, and service notes tied to each motor.
- Create engines with name, class, serial/ID, builder/shop, displacement, hours, timing, tuning notes, firing order, lash, plug gap, leakdown, and notes.
- Set an active engine to keep engine-related inventory and tuning notes organized.
- Use the builder/shop field consistently so you can find related records later.
- Update engine hours and notes after race nights, refreshes, or dyno changes.
Telemetry
Telemetry Viewer is for crew analysis and after-run review. It accepts SprintCar Pro JSON plus GPS logger TXT, LOG, and NMEA files.
- Click Select GPS/TXT file or drop a supported file into the import area.
- Choose a session and lap view, then adjust path smoothing, maximum GPS accuracy, spike filter, minimum path speed, and display units.
- Use the car path viewer, sample marker, playback speed, speed readout, lateral G, total G, lap table, and sample table to review the run.
- Use map replay to compare the driven line against the visible track surface one lap at a time.
- Export a smoothed CSV when you want to review data outside SprintCar Pro.
Team Manager / Crew
Team Manager controls who can use the team's SprintCar Pro access.
- Review the current team access card for your role and team ID.
- Owners and crew chiefs can add or invite crew by name, email, and role.
- Available roles are crew, driver, and crew chief. Owner access is protected.
- Use Save role to update a member's role, or Remove to remove access when a crew member changes teams.
Sync / Backup / Restore
Local Data Vault helps protect the team data stored in the browser you are using.
- Offline Readiness shows browser storage, network status, and whether the app shell is ready for offline use.
- Install App adds SprintCar Pro to supported devices for quicker access.
- Refresh Offline Cache updates the cached app shell for offline readiness.
- Export Vault Backup downloads a JSON backup of the active team vault in this browser.

Advanced Troubleshooting
I cannot get into the app
Sign out and back in through My Account. Confirm your trial, subscription, or membership is active. If the account page works but the app still does not open, contact support with your account email and the page you were trying to reach.
My changes are missing
Check that you are using the same browser and device, then look in Local Data Vault. If you exported a backup, import it only after confirming it is the file you want to restore.
Weather will not load
Try the track search box instead of GPS, refresh the weather panel, or enter manual weather readings from the track. Browser location permission may need to be enabled.
Telemetry import fails
Confirm the file is JSON, TXT, LOG, or NMEA. If the path looks wrong, adjust smoothing, GPS accuracy, spike filter, and minimum path speed before exporting or comparing laps.
Something looks incomplete
Return to the source module and save the missing record: setup, car, engine, inventory part, sponsor invoice, payment, expense, or telemetry file.
Offline mode feels stale
Reconnect to the internet, open Local Data Vault, refresh the offline cache, then reload the app. Export a vault backup before changing devices or browsers.
Getting Help
When you contact support, include your account email, device/browser, what module you were using, what you clicked, what you expected, and what happened instead. For data questions, include whether you have a recent vault backup.
