The 2ZR-FE Corolla has more to offer with proper calibration than the factory ECU ever explores.
The Toyota Corolla 2ZR-FE platform responds well to proper standalone calibration, and the factory ECU is the main thing standing in the way. The Tuned By Shawn PNP Wiring Harness Kit for the Haltech Nexus connects directly to your factory harness without any permanent modifications, giving the Haltech Nexus full standalone engine control. No cutting, no splicing, fully reversible.

The Details
