After watching a video on Rice Racing's website, there is an FD they were featuring that used a J&S Knock Retard unit.

More info on said unit.

Does anyone have experience with this product and how would you go about setting it up to use on a rotary?

 

The reason I am asking... I run a PFC which has no knock retard

 

Ah, ok. I was thinking more of just a safety. I plan to run WI and adding this along with a good tune would essentially make it as bulletproof a rotary can get.

I believe I saw a picture of Howard Coleman's FD with this unit attached next to the center console.
