Has anyone notice

[Stiv]

After a long drive on a highway (300km), TS becomes somewhat sluggish. There is no more hard acceleration and that sort of things. But then again, after a few hours of hard driving, it comes back to normal. Is that ECU adapting itself?
And if so, how should i drive it to make ECU goes to top performance state.

I also noticed that on my TS but i thinj is the ECU. It "learns" your driving style. A hard acceleration and things go back to normal.

i notice a similar thing , my car felt like it was pulling really hard , it still does , although i do alot of rush hour traffic driving , i do hammer it when there isnt traffic , but somehow the car seems to have not as much punch, now im not sure if it is just my imagination , i mean if i floor first and grab at 2nd , she still spins into second , so im not sure if its in my mind or what. i have an exhaust on the car , well , 57mm from the middle resonator to the back with a megan racing rear muffler.

i did hit the rpm limiter by accident 2 nights ago , but i dont think that can cause any damage , i mean that why the limiter is there right ?

is there anything else that could be wrong ? or is it the ECU messing me around ?

I have a huge problem. I was racing a Suzuki Swift 1.6 and instead of 3rd I git 1st at 90kmh. It reved very hard and since then I have knocking noise, very faint but the car pulls really bad. I compared it to a 1.4 diesel Yaris and from 0-130kmh the cars were equal.

Does anyone know what could it be?

That's the ECU doing it's job to conserve gas. It learns based on how much you accelerated on your last trip, among other things. The only way I know to pull faster is to drive faster (consistently) between trips.

Correct. Hitting the limiter every once in a while does no damage.

Weird... There's supposedly a safety feature on the Yaris where you can't shift to 1st while at certain speeds. Seems to me that you may have to give the mechanic a visit.

thanks for the feedback , makes alot of sense, i thought the ECU was messing with me
