Hi all

Can one of you help me out. My BT escos boost at 1,2 bar but without overboost.

My amal valve is the type with 2 connections on it. I can check the amal vavle by using 12 volt or? and how do i check if the ECU puts out the signal to the amal valve?

If i got i right the amal valve is the one that bleeds the air to the actuator during this overboost. Giving something like 0,2 bar in overboost


But when does the overboost kick in ? and what triggers it?


Hope you understand my problem.

 

Nobody??????????

 

the overboost feature allows it to run ( on a std car ) just under 1 bar for a few seconds in the mid range when coming on boost, it then tails off to the std boost of around 0.6 bar.
