Because you are spamming the board with multiple threads asking for the same advice.

This question was already answered for you, sounds like you need to verify your install.

When you start mixing parts from different vendors, then you run in to issues and support is difficult to give because there are unknown variables, that is one of the risks you assume when doing so.

Mixing parts has nothing to do with the electrical issues i am having... The controller itself is form Burger Tuning when that controller is hooked up the car throws codes.. The DME throws codes even with the injector rail unplugged. ..Even before starting... It throws codes with no power connected just its ground connected.. i know this because i was trouble shooting and removed the fuse for the controller still had the same codes... so i removed the ground wire also and boom no more codes from the DME. The Fuel rail itself has nothing to do with this controller giving me problems. That is nothing more then a aluminum rail using the same Bosch injector ever other rail uses..

Hey Steve. Figured i'd give you a little heads up.... So i was tring to use the Burger Tuning EWG harness upgrade and the Burger tuning Port Injection Controller. Note: Both from Burger Tuning.... So This afternoon i removed the EWG harness from the car and to my Suprise Suddenly the PI controller started to work correctly.. im guessing due to the fact the Harness upgrade uses BD25 Pin 16.. So if you would be so kind as to let me know what pin this should be moved to so i can use both of my Burger Tuning products... Thnx and have a great day..

Lots of people running EWG and PI controller, sounds like it's another issue with install or ???
