New Engine Management System offered for the 1NZFE

Does the Yaris share a common ECU with any other Toyota? Very interesting that AEM hasn't released a PnP standalone for it. I personally would not play with any system that requires the stock ECU to function for anything other than rudimentary functions like DBW or gauges

Appears to be the same as the 08 xB2 with the 09 Yaris. AEM has not even released the tC PNP EMS, which they have been speaking about releasing for the past 4 years. So that fact that the yaris does not have one, does not surprise me either.

Lastly, reprogramming the stock ECU with this unit works quite well on the tC and xB2. The tunes are crisp, offer lots of control and work well on all sides of tuning N/A or FI. I was a disbeliever too until I played with it.
