Master the my winter car save editor - safely edit money, vehicles, survival stats, and fix catastrophic failures. Whether you need a developer toolset, a trainer, or standard mods, we have the ultimate editor guide.
Save editors can permanently corrupt your progress. These tools were designed for My Summer Car and have partial compatibility with My Winter Car. Even with updated MWCEditor versions, unexpected behavior can occur. Always create a backup copy of your entire save folder before making ANY changes. Losing 20+ hours of progress because you didn't spend 30 seconds copying a folder is a terrible way to learn this lesson.
Backup Location: Copy entire folder at %USERPROFILE%\AppData\LocalLow\Amistech\My Winter Car to a safe location (Desktop, Documents, external drive).
There are currently two save editors available for My Winter Car, each with different strengths and limitations. Both are community projects adapted from My Summer Car tools.
Developer: Marcinosky/Shedmann (community update)
Status: Active development (Dec 2025 - Jan 2026)
Version: Updated for My Winter Car specifically
Developer: durkhaz (original MSC tool)
Status: No official MWC support
Version: Designed for My Summer Car
Use MSCEditor only if: (1) MWCEditor is unavailable, (2) You're editing non-Rivett vehicles, (3) You need proven MSC compatibility for imported saves
Download from Nexus Mods →Use MWCEditor (Marcinosky version) for 95% of situations. It's specifically updated for My Winter Car and handles the game's save structure more reliably. Only fall back to MSCEditor if you're working with imported My Summer Car saves or if MWCEditor is temporarily unavailable.
%USERPROFILE%\AppData\LocalLow\Amistech\My Winter Carsavefile.txtCRITICAL FIRST STEP: Before downloading anything, backup your save:
%USERPROFILE%\AppData\LocalLow\Amistech and press EnterChoose one download source:
Option A - GitHub (Recommended):
Option B - Nexus Mods:
No installation required - it's a standalone executable:
⚠️ Make sure you're using the x64 (64-bit) version - 32-bit version does NOT work with My Winter Car.
MWCEditor should auto-detect your save folder on first launch. If not:
%USERPROFILE%\AppData\LocalLow\Amistech\My Winter Car✓ Success indicator: You'll see your player name, money amount, and vehicle data populate in the editor interface.
Edit your save data carefully:
🚨 NEVER edit while game is running - this WILL corrupt your save. Always close game before opening editor.
savefile.txtThe most popular save edit. Perfect for skipping the early-game money grind and focusing on building your Rivett.
How to Edit:
999999 for ~1 million MK)⚠️ Recommended Amounts: 50,000 MK = comfortable early game, 200,000 MK = all Rivett parts + safety buffer, 999,999 MK = effectively infinite money
Rescue vehicles stuck in forests, underwater, or off-map locations. Essential for recovering from catastrophic failures.
How to Teleport:
1.0 meter🚨 Why Height Offset Matters: Without the +1m offset, vehicles spawn embedded in the ground, causing physics explosions that launch them into orbit or destroy them instantly. Always add vertical clearance.
Modify all 6 survival stats to prevent death or skip tedious maintenance. Useful for testing or creative builds.
How to Edit Stats:
0 (full) or 100 (starving)0 (hydrated) or 100 (dehydrated)37.0 (normal body temp °C)0 (rested) or 100 (exhausted)0 (empty bladder)0 (no addiction) - WARNING: Setting this too low removes beer requirement!⚠️ Problem Stat Caution: The "Problem" stat represents alcoholism. Setting it to 0 means you won't need beer to survive, which removes a core survival mechanic. Consider setting to 10-20 instead to keep beer requirement but reduce urgency.
MWCEditor's killer feature (added Jan 2026). Shows which Rivett parts are loose, damaged, or missing. Essential for diagnosing why your car won't start.
How to Use:
⚠️ Current Limitations: Wiring system not yet implemented in report. Electrical issues won't show up here. Developer is working on adding wiring diagnostics in future updates.
Fast-forward to specific times for job scheduling, skip nights, or reach weekend events like ice racing or Flea Market.
How to Edit Time:
🚨 BROKEN IN MWCEditor: Time/weather editing currently has bugs. Values may not apply correctly or may reset. Developer is aware and working on fix. Use in-game bed sleep for time skipping instead (safer).
Tighten all Rivett bolts to 100% without manually using wrenches. Prevents parts falling off during driving.
8 (max tightness)Get exact X/Y/Z coordinates for custom teleport locations. Useful for creating custom spawn points.
Add items directly to player inventory without shopping trips to PSK or Fleetari.
Restore part condition to 100% NOS quality. Useful after crashes or wear damage.
100Some MSC achievements may be editable. MWC achievement system unknown.
Clear police fines from speeding, expired inspection, or fuel tax violations.

My Winter Car folder stored safelyMy Winter Car supports importing progress from My Summer Car, allowing you to carry over unlocks and some items. This is useful for players transitioning from MSC to MWC who want to skip re-grinding basic progress.
%USERPROFILE%\AppData\LocalLow\AmistechCRITICAL: Back up your current MWC progress before overwriting:
My Winter Car folder (same Amistech folder)savefile.txt instead⚠️ Will NOT work on existing MWC save - must start fresh game for import to trigger.
After importing MSC save, you can use MWCEditor to:
Recommended: Use MSCEditor (original) for editing imported saves initially, as it understands MSC data structure better. After first few edits, switch to MWCEditor for ongoing modifications.
