Fish CP3 Controller

Our Fish Tuning Advanced CP3 Controllers will work with other kits (e.g. from ATS, PPE or anyone else). Please specify either Duramax (LB7/LLY, LML/LBZ/LMM) or Cummins. Please note: it does NOT matter what kind of pump you have, the one you need is defined by your ECM. 

And yes, it really is as small as it looks, it's only 1" X 1" X 1/2" and easy to hide almost anywhere. Our triple CP3 Controller is hardly bigger - 1 3/4" X 1" X 1/2"

We can also make quads and even quints by special request.
