2004.5 through 2007 5.9 Cummins Smoke Switch
This is a partially tested idea right now, and not really a product as much a gimmick you can build and install yourself. Everyone was looking for a great way to make a "Smoke Switch" for the 3rd gen cummins trucks, and I wanted to enhance it. With the flip of a switch this circuit will tell your PCM that the turbo is pushing full boost, and at the same time it will open up the electric wastegate solenoid thus making no boost at all :)
I tried a smoke switch that just fooled the MAP but it became a performance mod, just adding more fuel and spooling up the turbo. This new design should work better!
Some examples.
My boost gauge with the smoke switch OFF
My boost gauge with the smoke switch ON
Isn't that fun?
Thanks, please report back on how it works for you!
