I'm driving a 01 corolla as my beater this winter, and came across something interesting.
I get a ridicilous amount of engine knock at WOT and the ecu retards timing massively resulting in an even slower corolla.
It's sooo slow I almost go backwards.
Today i accidently put in 94 octane cus I was too busy checking out a chick in high heels pumping gas, the apple bottom view wasn't the only benefit of this mistake, the engine has completely stopped knocking, ign timing is at high 20's at load and there's actually power.
i know there's more power too, cus it spins the wheels from a stop. it didn't even do that in the rain prior to this.
the car is completely stock other than my scanguage, which i'm using to monitor water temps so i know when to blast the heater and not get cold air. the only motor work that was done was the head gasket was changed years ago.
what could cause this? why does it knock with 87 and not 94, when it's meant for 87. could the head gasket result in a higher compression that would need knock resistance power of 94?
or is it just coincidence? and i shouldn't get used to the car moving fast?
