Fish Tuning Advanced CP3 Controllers

Do you sell CP3 Conversion Kits? Replace failed CP3 Controllers? 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.

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.

Please contact us directly at orders@fishtuning.com or (310) 499-0989 for international shipping, more information or large quantity orders.

Installation instructions located here.

This is a Cummins version:

This is a Duramax version. The quarter is there for a size comparison.

And here is what our triple controller looks like, slightly bigger, but still smaller, lighter and easier to hide than any other controller made and we usually have them IN STOCK.

Need to order one for your truck?

If you have a LBZ, LMM or LML Duramax make sure to tell us which one so you get the proper controller.

If you don't say, you will get one for an LB7 or LLY. Please contact us for international shipping prices. Sorry, the website only quotes prices in the US. If you order outside the US, we will contact you for more money for shipping.
