Switching from low to high boost.

Not sure if this is the right place to make a thread, but I hope so.

Just wondering, if I'm driving about, and I'm switching it from low boost to high boost, then putting it back on low boost. Can this damage the car in anyway?
Should I be driven from the start on 1 or the other?

I'm new to a glanza and the hole turbo setup.
Thought I best ask then just wait around for something bad to happen.

Cheers

Hi mate all that happens when you press that button is the hi/lo boost solenoid opens the wastegate more somebody correct me if ime wrong its like on an adjustable actuator its just like you keep getting out and adjusting the screws on it lol it shouldn't do any damage most people bypass them tbh hope this helps

Thats right starlet gt.neal

being on low boost will use more fuel this has been mentioned before, It will also give you full boost in 1st and 2nd gear if you remove/bypass the solenoid.

lol, nope.. they didnt install this feature to do damage.. the high/low turbo feature was designed for icy/snow covered roads.. for all the world, its a boost controller with only 2 settings... its just to help stop excessive wheel spin on icy roads... it does use more fuel on low mode but its not that noticeable nor is it bad for the engine

well i did not no that you use more fuel in lo boost ! does anyone no why this is ? i still have lo and hi boost in operation ! im running .8 bar of boost with just a decat and a manifold ! and must admit i have it lo boost all week on my drive to work as i thought it would save me a bit of fuel !

Just keep it in Hi at all the times.
Here are some tips what i do to save fuel;
1. Dont go above 2k rpm
2. Check tire pressure
3. Swicth of AC and open the windows and enjoy the breeze


Place your right hand on your heart and say the following - "I solemnly swear that I will conserve fuel as much as possible and try to use it economically. I shall dedicate my mind, body, heart and soul for the conservation of fuel."

short and sweet.. less air from the turbo = more fuel to compensate... only little bit more tho :)

i think its because all it does is cut the boost but still uses the same amount of fuel basically the fuel map stays the same in both modes

It's very simple, lowering the boost pressure will result in a lower torque output from the engine at any given RPM, a lower torque output generally causes the driver to push the engine a little harder and changing gear more often, all this leads to an increase in fuel consumption. When it comes to fuel consumption, efficiency is the name of the game.
