Um the ECU controls your rev limit? your fuel injection?

what i am wondering..can toyota limit an ECU or do they need to put a whole new one in.

why do i ask this.. since i took my car to Toyota for a little fender work...it doesnt feel right...feels like it has lost power over the entire band. now i havent really pushed it into lift to test.

it has gotten really hot suddenly in the last week here. could that do it..i noticed a lot of people saying their celicas are moody with the power..but seriously..could toyota just modify an ECU and limit it in a matter of 5 hours which is how long they had my car..OR is this a figment of mind/weather.

yes they can.. suposedly they have a hand held programmer that can write to the ECU.. can change pretty much whatever.. but this is all speculation on my part from what Ive been told.. would they do it though, most likely no
