Haltech Elite Fuel Management System

Haltech Elite 550 ECU & Adapter Kit 

Ditch the headache of wrestling with ancient, 20+ year-old factory fuel injection electronics and bring the classic rig into the modern era. To create a top-tier engine management solution that is incredibly user-friendly for beginners yet fully versatile for advanced tuners, we partnered directly with the EFI specialists at SNP Speed Innovations (#TunedbyGabe). The resulting Haltech Elite 550 Kit completely revolutionizes how your Toyota 22RE platforms, delivering crisp throttle response, modern reliability, and total tuning control.

Designed to be as close to a true plug-and-play system as possible, this kit plugs right into your factory engine harness and utilizes a precision-engineered sub0harness to cut installation down to under 3 hours. Best of all, it arrives with a pre-loaded startup tune directly on the ECU. This allows you to fire up the engine immediately upon installation, though further custom tuning will be required before hitting the street or trail.

Specialized online technical support and remote online tuning sessions are available solely through SNP Speed Innovations.
