We use a tuned Scion xD ECU for our MR2 2ZR swaps. Of course, we're also good at outgrowing this. When adding boost or searching for maximum NA power, we switch to an EMU Black standalone ECU for total control. When designing this product for use primarily with MR2 swaps, we figured we may as well make it work the donor vehicles. Compatible with the following vehicles and swaps utilizing these harnesses.

Scion xD with 2ZR.

Toyota Yaris 2006-2010 with 1NZ.

Toyota Corolla 2009-2010 with 2ZR.

Compatible with manual transmission vehicles only. Comprehensive basemap provided for use in MR2, xD or Yaris. Includes CAN protocol and all connections needed for all factory gauges, AC, cruise control, etc. Physical fitment and CAN communication have not been confirmed on Corolla. Photo shows install in Yaris.

Adapter includes connector for easy addition of extras - wideband, boost control, fuel pressure, EDL1, etc. Comes wired for the included Bosch 4.9 wideband O2 sensor.
