Hi
Can anybody help me? Have an Evo 4 which has a digital boost controller, which im not totally sure how it works.
It only has two buttons on it and apparently four settings to choose from. Which are 9.1, 10.4, 9.9, 17.1. presumably the psi.
When i got the car it was rapid, and was on the 17.1 setting. got told this was a bit high, just over 1 bar so i managed to fiddle with the buttons until got another setting.
Now it only boosts out a max of 10 psi.
I tried changing it back to original 17.1 setting but despite it supposedly accepting this setting, if i watch the boost under power it still max's out at 10psi.
Does anybody else have this sort off gauge?
