Yaris Ts Idle Revs

[matt Tspt]

Can somebody tell me what rpm there yaris ts sits at after its been driven for a while and warmed up cause i changed mine so that it ticks over louder but was then told it can be quite bad for the car.Ive changed it back but just want to make sure.

Cheers

I think normally it's 575RPM but mine varies from 500 - 900 depending on air con & stereo.

The idle rate changes with the bass line. Alternator is only 50 - 60A though. Not much good for amp's.
