Turbo: —
Big turbo + Methanol (M1) unlocks high boost (up to 50 psi) and 1000+ whp potential in this sim. Use Boost vs RPM to ramp boost in after spool/traction.

Cell: —
Fuel trim: higher = richer. Range: -5 to +5.
Ignition Map (°)
Cell: —
Commanded timing. Effective = (Ign - KR).
Boost vs RPM (psi)
RPM: —
Used only when Boost Mode = Boost vs RPM. Table values are clamped to Fuel/Turbo max boost.

Spark Plug—
Quick plug read (sim):
🔴 Timing mark (red on strap)
• Middle = good
• Near base = too much timing / too hot
• Near tip = not enough timing
⚪ Porcelain
• Light gray = good
• White = lean / hot
• Dark = rich
⚫ Peppering
• Dots = knock (KR)
⚡ Gap
• Wider gap + big boost = misfire risk
