so i've had it in for a few days now. it's a pretty interesting device. i have the sport setting on level 3 and the race on... idk like 8 or something. i do not use the race, as it did not seem to act any different on this low powered car than the sport setting. i found i leave it off in the morning on the way to work, and i leave it on the sport mode after work. it does open the throttle faster, but with the lack of power it does not accelerate any faster. the big difference i found was in 5th gear and when climbing hills. you don't need to bury the pedal foe acceleration! it's pretty much wot at maybe 25-30% depressed. it's really nice!
there might be a real difference on a stock TB and manifold. the pedal lock out feature is a nice passive security device. (i'm sure the valet mode is nice for boosted cars) it makes 5th gear a lot more responsive.
i like it. i sleep a lot better knowing there is yet another passive device on my car. (i don't like alarms, i like disables) it is pretty expensive for what it is, ($279USD) but no one had reviewed one for a yaris, so someone had to buy one. (they are made in Greece)
