>Xtreme, what are the drawbacks for the J&S other than cost?
>id be willing to try it on the new engine.

I have spent some days here researching more about the J&S, looked for testing done on it, ect. It seems it came about for the RX-7 guys. A lot of them use it, and they have relayed info back to the devloper/builder of the J&S. They have come out with the 3rd gen prodcut now, and is pretty versitile. THE most imortant drawback that I can see from this unit, is the sensing of the actual knock. Every engine has a different knock frequency, but they all have a general frequency range of which knock has. Noisy pistons, and other engine noises can confuse the J&S, and cause uneeded timing retard. I read a post or two like this when i was doing my research. This was with the older units also. The idea is great, and for some people who use it, it works excellent for them, has saved their motor many times. Some have probs with it. Its a toss up really. There were more positve comments on it than negative, and most agree that it works at saving their engines from the destructive forces of detonation. I'm still researching the whole topic, and trying to find more info from actual users of the J&S. As of now, I still plan on buying one. Whats another 600 bucks?? hehe...oh well..
