Path B: Aftermarket ECU (Haltech, Link, MaxxECU)
- Pros: No immobilizer, full tunability.
- Cons: You lose variable valve timing (unless you buy a $400 driver module).
- Wiring trick: Use the factory PDF to find the VR crank sensor (pins B-6/B-7). These are high-resolution 24-2 or 36-2 trigger wheels. Wire them directly to the standalone’s crank input with no resistor.
