Offering for sale, a complete Apexi NEO Air Fuel Controller in perfect working condition with a clear, scratch free color display with the original, peel off plastic protector intact and never removed. I will include the wiring harness, installation and instruction manuals. This unit worked excellent on my car to dial back in my air fuel mixture through out my RPM range and gain back some 50 RWHP I lost after major modifications to my intake system.
