Boost vs Time is ideal for FWD drag logic: softer early boost improves 60’, then ramp hard later to carry mph. WG Duty is a simple closed-loop “chaser”.
Calibration Fuel + Timing + Boost
Fuel Map (Trim)
Cell: —
Fuel trim: higher = richer. Range: -5 to +5.
Ignition Map (°)
Cell: —
Commanded timing. Effective = (Ign - KR).
Boost vs Time (psi)
Time: —
Used for WG duty control and drag sim. Start soft (0–1.5s), ramp after.
Values clamp to Fuel/Turbo max boost.

Inspect Spark Plug—
Quick sim-read:
• Peppering = knock/KR
• White/hot = lean/hot
• Dark/sooty = rich
• Blowout = too much boost for plug gap/energy
Run a dyno pull, then inspect plug for analysis.
