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.

This has been a great discussion and hope it opens some eyes to what a great platform the Yaris could be.

Lack of an ECU hack and simple lack of performance data with various mid-level suspension upgrades are all we need to keep the ball rolling.


I installed TRD springs, Kokico Blue shocks, and a TRD sway bar on the rear axel today, its like a new car literally. Doing the fronts tomorrow. I have a funny feeling that the car will handle better with the stock shocks/springs up front, maybe even better with the front sway bar removed. But we need data. Can you tell I am an engineer (Harley-Davidson)?

Keep the dialog going, I don't mind being told I am wrong about things, it wouldn't be the first time my info was out of date.
