It's just a billet alumnum piece that sits on top of your throttle body that prevents your map sensor from seeing boost. Because our engines our used to only working in a vaccum, when they see positive manifold pressure, the ecu freaks out and throws a code because it thinks something is wrong. The missing link will allow the map sensor to only see vaccum by bleeding off the positive pressure created by the turbo via a one way check valve where air can only go one way.

 

Project T-25 D16Y8 is using one for his setup, he has a pretty good picture of how it looks under management. I will give you an idea of what it is.

Oh and I got mine from here http://www.group5motorsport.com/cgi-...SE-MissingLink
$55.00, the also have pictures of the part.

 

is there a "homemade" way around this?

would a missing link meant for a D16 fit a D15b7?

 

I needa know how to build one...I seen them go for 20.00 on h-t but I still dont like that price...
