Toyota MR2 / Celica 1ZZ / 2ZZ Rev 2 Ecumaster EMU Black ECU Kit

The Toyota MR2 / Celica 1ZZ / 2ZZ Rev 2 Ecumaster EMU Black ECU Kit is designed for Toyota Celica and MR2 applications using 1ZZ and 2ZZ engine setups.

This kit includes an Ecumaster EMU Black standalone ECU and a dedicated plug-and-play adaptor, providing a clean standalone ECU solution while retaining key factory vehicle functions where compatible.

The Rev 2 adaptor features a new and improved design developed to solve previous Celica fitment issues. Earlier parallel connection layouts left very limited space for the ECU and wiring, often requiring heavy ECU box modification while still causing problems with ECU placement. The revised design provides a neater and more practical installation.
