Turbo kits are not "Bolt on Heaven".
Old saying: If a turbo you have tried, then a piston you have fried.

Wouldn't it be nice to not have to worry about a "boost spike", or crap gas, or leaning out?

I put together a home made turbo for my Fiat back in the early eighties. I blew the head gasket at least three times, so someone suggested that I should get the head o-ringed. Then, instead of blowing head gaskets, I started breaking pistons.

It was really a drag, every time you stepped on the gas, you had to strain your ears to listen for detonation, and back pedal it if you thought you heard it, unless there was some turkey alongside, trying to pull you, then, of course, you couldn't back off, you just prayed as the boost came up.

Back then, there weren't any timing computers or fuel controllers. We had to make our own water injection. In the winter we had to walk through six feet of...oh, wrong story.

About that time, Porsche came out with the 944 Turbo. Road and Track magazine said it used Bosch electronics with a knock sensor to retard timing. What was really cool, was that it retarded only the cylinders that were knocking.

That's where I got the inspiration for the SafeGuard. I was an electronics technician in aerospace. I became obsessed with the idea of building my own knock controlled ignition. By then, I had gotten really tired of rebuilding the old Fiat. How much better to have electronics listen for knock for you, and then automatically control the timing?

The SafeGuard was finally brought to market in '91. It's simple in concept, but I had a lot to learn before I had a design that worked.

Everybody says their kits don't ping. Why, then, do engines blow? Anyone that sells you a kit and says you don't need a SafeGuard is just trying to ease the financial pain to make a quick sale.

Yes, we make a profit building them, but they were designed to fix a problem on my own car.

Since I recently changed my setup from an A'PEXi PowerFC to a P28 based Hondata setup(both of which do not have an active knock retard feature...if you're knocking, the ECU does not retard your timing)

I do not know whether this is what you were trying to say, but the P28 doesn't even have a knock sensor input. The sohc civics have never had knock sensors...

Dustin

can't say too much for there support or lack of, i've sent emails and never received one back, oh well. Good product nevertheless

I'm running a j&s safeguard and i know it's saved my engine on at least one occasion (when i saw my boost briefly spike to 11psi and i saw the safeguard do a little retarding).

Does anyone use a j&s safeguard with the j&s knock sensor? is it significantly better than the stock knock sensor?
