i just took out my intercooler and i noticed that my EVC was tapped at the rubber coupler of the intercooler, i am installing a larger intercooler and i was wondering where you guys tap the middle hose of the stepping motor. Thanks in advance

Do not have my car here right now and I cant remember which nipple on the motor goes to what. One hose goes to manifold, one goes to wastegate and one hose goes to nipple off of turbo or the nipple coming out of the turbo. Be sure to look at the directions, I use an external wastegate which has one of the hoses teeing off to the other nipple on the wategate. The internal wastegate setups are slightly different.

Oh, by the way, tapping boost from a nipple on the IC connector is just lazy and a really bad way to do it.

If me memory serves me correctly, the middle nipple would be connected to an external wastegate.

On the EVC, all 3 hoses are used. You can find the install guide here (http://archive.socalevo.net/docs/manuals/HKS%20EVC%205%20Install%20and%20Setup%20Guide.pdf) on socalevo. Right click and save as, it's 10.5 MB. I also have the user guide if you need.

does it matter what HKS EVC u use ? mine is older and im not sure what the connectors go 2 coming off the controle unit itself...its got one roto. nob (left side) and 4 buttons (right side)... one con. goes 2 the step motor the other just sits there...
