OK one of the guys on the board got me looking for this in my lab... I lost it. Searched for 3 weeks and could not find it. My wife found it in 3 minutes... I wonder where SHE had put it?

OK here is what we have a J&S Ultra Safeguard 1 Ch/2 Ch knock retard and boost retard Controller. I bought it 6/2002 new. It has never been installed. I HAS been run on a computer controlled engine simulator to verify that it does all that John Pizutto said it would... and it does it quite nicely. So you get a independently verified unit!



Comes with the neat little royal blue bag that Shirley Pizutto made for it, complete with gold braid:



Has all the original doo dads for installation, never cut, punched or scratched:



Here is one of the instruction sheets, particularly for HONDA: Note this Safeguard has the ability to mask phantom knock during VTEC Changeover:



Ahhhh now price you say? John at J&S is currently listing the unit at $495 bucks... I paid $488 shipped back in 2002... for this fine unit.

Where should we start? Brand new unit... and I DID NOT unpot it or otherwise penetrate the case... a few X-rays maybee... ... Perhaps we start around $400 skins... if out of line we will be reasonable. Paypal or Check with time to clear.

BigMoose: I was clicking around and ran across a link to your knock sensor page. Great instrumentation! Wish we had it when we started.

Shirley and I started experimenting with knock sensors in 1984. We'd take our turbo Fiat out late at night and make cassette recordings from a knock sensor. I had a Sony SuperScope table top recorder on my lap, a cheap scope on the floor between my legs, and audio cables going everywhere. It was a major accomplishment just getting in and out of the car.

On the bench, I would play back the tapes into my prototype knock detector system. It was analog back then, but I went digital in '89, running the algorithm on an 'HC11 processor.

We gave a couple "evaluation" units to one of the Japanese performance companies, hoping for a big sale. Never heard back from them, until the guy we were working with left the company a few years later. He said he went back to Japan on one trip, and they had our units completely unpotted. Good thing we use a processor with a security bit. Try to read the code, and it erases itself.

 

John,

Good to hear from you again, and good for folks to get a little more of a history lesson from one of the guys that "paved the way." The page of mine that John is referring to is most likely this one http://www.mtggraphics.com/big...k.htm

I can relate to your descriptions, I was test driving a truck during Christmas vacation, trying to balance a digital voltmeter, a digital scope, and a PC data acquisiton system while I was trying to do 1320 foot runs with icy patches on the back roads... what a hoot. It gave a new meaning to "Don't research and drive!"

John, oftentimes I wish you were next door, it would be fun to collaborate on something new and out there. Don't make yourself a stranger. I think you have my email already, if not IM me for it if you want it. Take care and thanks for the history.

 

Bump for a great unit

Indeed!

While cleaning my garage, I just (last night) found a brand new j&s unit with the knock/af monitor. I've had it since late 2002 and had forgotten all about it, but i'm so glad to find it. It will come in handy with my turboprelude project that is coming to a close!!
