2018 1.5 auto upgrades? - Toyota Yaris Forums

Update: found another with my same issue. I'm not crazy afterall, the ECU is indeed limiting throttle to 80% max, and only 50% from a stop at WOT. This PLX device mentioned is cheap enough to try and seems to solve the "lag" issue but not the 80% problem. I'll be happy enough with that for now until I swap throttle bodies to a 2ZZ unit, which takes care of the issue altogether.
