PROJECT BLACK PEARL

AI-Assisted ECU Calibration & WRX Development Platform

310 WHP @ 12 PSI | VF22 | Custom ROM Engineering | Live AI Logging

Current Calibration State


  • Target Boost: 12 PSI (heat-consistent taper)
  • WOT AFR: 11.3–11.5
  • Ignition Advance: +1.5° conservative midrange
  • Max Feedback Knock Observed: -1.4° transient
  • IAM Stability: 1.00
  • Idle: 875 RPM stabilized

ECU Development Strategy


Boost Control Architecture

Wastegate duty cycle reshaped for midrange smoothness and high-RPM taper stability.
Prioritized consistency over dyno spike numbers.

Fueling Strategy

Open-loop fueling optimized for thermal safety and knock suppression.
Closed-loop cruise retains drivability and economy.

Ignition Strategy

Incremental timing advancement validated through multi-log review.
Emphasis on repeatable performance and long-term reliability.

Knock & Safety Logic

Conservative retard limits with real-time AI-assisted log monitoring.
No aggressive timing chasing — stability prioritized.

AI-Assisted Calibration System


  • Real-time OBD2 logging via Tactrix OpenPort 2.0
  • Python-based log ingestion and trend detection
  • AI anomaly detection for knock behavior patterns
  • Boost and timing trend correlation monitoring
  • Local LLM-assisted log interpretation pipeline

The system flags irregular correction behavior before mechanical thresholds are exceeded,
supporting disciplined incremental tuning methodology.

Recent Calibration Revisions


Revision v1.3 – Boost Stability Update

Objective: Reduce midrange spike.

Change: -4% WGDC adjustment at 3,800 RPM load column.

Result: Flatter torque transition, reduced knock correction.


Revision v1.2 – Ignition Curve Refinement

Objective: Improve throttle response under moderate load.

Change: +1° advance in 2.2–2.6 g/rev range.

Result: Improved response without IAM fluctuation.

Stage 2 Development Roadmap


  • VF22 Turbo Integration Addons
  • 1000cc Injector Scaling & Latency Modeling
  • AEM 440 E85 High Performance Fuel-Pump
  • Rev9 TMIC Thermal Efficiency Testing
  • Target Output: 305 WHP (conservative street calibration)
