Disconnected blow-by hose?

As a matter of surprise, Blow-by gas combustion hose was not connected, between cum-cover and intake air way after air flow meter. Judging from the clump mark on the hose, so long period of time this condition was left undone. Deeper consideration led me the conclusion that measuring mal air volume imparting less air flow because of opened blow-by gas hose. Also, blow-by oil mist gas had been scattered in the engine room.

I'll come to know how the fuel consumption would be, better or not. Any way, different signal from the air flow meter would any transition to ECU. Former mischievous person did unusual attitude? 

Vehicle as a tool

Spending all day long yesterday, I visited six tombs, 12 flowers were prepared for that. Driving Yaris Z with suspension spring harder modified, working fatigue was not so much as imagined. By the way, best designed setting by the manufacture's engineers cannot be exceeded by any layman tampering. The only way to make some customizing is minimize the constructive tolerance as less as possible.

The most effective element is thrust angle in the suspension construction. This proposition is relatively easily done if the measuring and scaling devices could be obtained if it is done by DIY.

Though some keen observation skill and concentration are required, driving feel changes apparently after the adjustment could be carried out adequately. 

Computerized emission control and various safety system prevent an ordinary user to modify a secret in the black box.
