Hi All,

Just a quick question...

With regards to a external wastegate, Is there a setting on the ECU that needs to be changed between external and internal wastegate...?

Basically my car is setup for a VF35 & Internal wastegate... I have now changed to a T518Z & External wastegate (Internal welded shut)... I can hear a blowing noise and slight gasses coming fromt he screamer pipe, I wondered if this was to do with wastegate duty etc holding it open ever so slightly... Car is in for a map Friday so if that will fix it then lovely jubbly! If not I need to work out why its doing what it is?

I remember from my last map the mapper saying "Wastegate duty was at 55" if that helps?

Cheers!

I believe the plumbing of the boost solenoid is also slightly different.

I have a Apexi AVCR, and that has 2 distinct plumbing diagrams, one with a internal WG, and another with an external WG.

It is plumbed in correctly for his application

The ECU only "sees" the boost solenoid, so as long as that is plumbed in correctly it can be mapped to suit.
