Quick answer
Read the table first: each row is a baseline code for Global extreme cars at the listed ECU level. Change one digit at a time when testing.
Pair with tier list: pick your car on Extreme tier list, then return here for the matching code.
What the 5 digits mean
| Position | What it controls |
|---|---|
| Digit 1 — Engine | Lower favors acceleration; higher favors top speed. |
| Digit 2 — Tires | Lower adds grip; higher adds drift slip. |
| Digit 3 — Electronics | Controls drift angle style. |
| Digit 4 — Chassis | Higher values add stability in linked corners. |
| Digit 5 — Body | Downforce for high-speed stability. |
Testing workflow and limits
How to test a setup safely
- Confirm 25/25 upgrade and the ECU level shown in the table.
- Enter the baseline code, then test on the route family you actually queue.
- Change one digit at a time so handling differences stay readable.
- Re-check after a patch, ECU unlock, or tier-list shortlist change.
What this page does not claim
- Not an official NetEase tuning sheet.
- Not a guarantee that one code fits every track in Global ranked.
- Not valid for pre-25/25 builds — use in-game default until max upgrade.
What to watch during testing
| Signal | Why it matters |
|---|---|
| Corner entry | If entry feels vague, tires or chassis usually need the first change. |
| Mid-corner stability | Linked corners expose setups that only work on straights. |
| Throttle exit | A fast lap on entry can still lose time on exit. |
| Lap repeatability | Keep the setup only if it repeats under pressure, not on one lucky lap. |

Extreme tuning FAQ
Are these extreme tuning codes official?
No. They are community-tested baselines from racingmaster.gg at ECU 0 (or ECU 5 for Normal Standard cars) with a 25/25 upgrade. Test in your own build before ranked.
Should I tune before reaching 25/25?
Keep default until 25/25. Partial upgrades change handling unpredictably.
How do I pair this with the extreme tier list?
Pick your car on the extreme tier list, then apply the matching row below. Re-check after each ECU unlock.
What if a code feels wrong after a patch?
Re-test one digit at a time, then file /contact with the page URL and the source that shows the updated baseline.
