Well this maybe a first, my ECU has a bosot leak in it.
I connected up a boost pipe to the ECU and as soon as it's connected vacuum dropped from 0.70 bar to 0.28 bar. There is an almight hiss from the ECU on boost and a faint one off boost.
Before you ask it's no the boost hose as when connected to a spare boost gauge i have there no leak in the hose.
I also changed the hose as a test to some industrial vacuum gauge with 2-3mm walls on the hose!
Whats inside the ECU that could leak?
