You had to have taken a 30% hit just running 93 octane. Fact is there is no elegant OBDII scan compliant way to tune a FI Yaris. If your running a piggy back to keep the OBDII port you must be running dangerously lean to not see a decline in mpg. If you threw away the OEM ECU and OBDII you have an off-road vehicle in most states.

Once I have a wideband I'll be able to tell you more about the AFR, but for now I can tell you I'm running Shell 93, getting 35 MPG and pushing lots more power.
