Have any of you have seen the 2 Fast 2 Furious movie were the police shoot some type of electromanetic weapon at the car to fool the car computer so the car slow down?
Its this is true? Do this weapon exist?? What exactly do this weapon to the car computer? Can I make myself something simila??? Do it is complicated?

It was probably an EMP generator. It fries the control electronics in a car which makes the engine stop working. I don't know if directional ones exist, but EMP 'bombs' are possible that fry everything in an area.

Yes, directional ones do exist. They were being tested by the state police in my area a few years ago. They were launched from under the patrol car and was activated by some sort of proximity sensor on the device. They would stop the car dead in its tracks, well after it rolled to a stop anyways. I don't think they ever went beyond the testing phase though.

it wasn't directional, just low powered. it only had enough power to disable anything like within 5 ft. it was under the car so it didn't affect anything else.

Obviously, the movie version doesn't exist. It's just a stupid prop in an even dumber movie. However, there is a real version. It looks like a small skateboard that is mounted under the front bumper of the patrol car. It is launched using model rocket engines, and designed to get underneath the car you are chasing. There are large foil contacts that stuck up like leaves. It delivers a HV pulse to the car, which is supposed to lock up/burn out the computer. Seems to work well in all the demonstrations I have seen (on TV).

Aaron, I remember I saw the same TV demostration....That why I was asking if that weapon exist?
But what is HV pulse?? What I mean is how this think exactly work to lock up/burn the IC´s inside the car computer?
Do its dificult to produce the HV pulse?
THX,

It's just a standard HV generator, which probably pulses at some high frequency using a capacitor as a discharge point....Like a big strobe circuit. The contacts conduct to the body of the car. Like anything else, the ECU in the car is sensitive to surges and spikes.

Have any of you have seen the 2 Fast 2 Furious movie
•No.
were the police shoot some type of electromanetic weapon at the car to fool the car computer so the car slow down?
•Sounds impractical. You'd have to carry a rack of weapons, one for each major make of car. that'd take up a lot of space down under the car. Then you'd have to dial up the right one when you're supposed to be driving. Then you'd have to aim and fire while driving fast. The air force spends around one million dollars (US) per pilot to teach people how to do this well. How much training $ do you think they'd spend on training officer Friendly? Also, what happens if he shoots it and then runs it over?
Its this is true? Do this weapon exist??
•I don't believe it.
What exactly do this weapon to the car computer?
•Nothing, because it doesn't exist.
Can I make myself something simila???
•You could make an EMP device.
(is) it is complicated?
•You could make an EMP device, I don't know if you could make a car killer though. If you have IC parts out in the open they are exposed to passing EM pulses. When they are plugged into the car the entire body of the car is acting somewhat like a faraday cage, protecting them from passing waves. If you attempt to bypass this by physically touching the car you still have to get your pulse through the car battery. Part of the function of that big 12 volt battery is to act as a capacitor and smooth out passing currents.

Now, obviously the movie was stupid and this "weapon" doesn't actually exist, but there are a few points I would like to make.

Why would you need a weapon for each car? Big spike shoots into side of car, delivers HV pulses to kill the computer. Sounds pretty generic to me. It's doubtfull that Fords would take "different" HV to stall then Chevies.

The version I saw was several years ago on Discovery. The demonstration was very effective against a modern car, and the device looked easy to use. However, I can't see it having any effect on an older car (carb, distributer) since there's nothing to "fry". Not sure if it's in use, because it would be difficult to "aim".

If you look at Malibus first post, he was describing a device to *fool* the car, not kill it. such a beast would have to be specific for the chip it was fooling.

Theory 1: Have you ever heard of something called Universal Device. It will "fool" different chips and ics that it is programmed with. Or
Theory 2: instead of "fool" It probably Jam the the Ics and chips. Therefore, it will jam the ics and chips nomatter what car brand.

No.

??? Not following you

How?
Therefore, it will jam the ics and chips nomatter what car brand.
You might want to look into how electronic countermeasures work in military aircraft as a baseline to speculate out from.

Hey, on the internet you can be anybody you want. No problen.

I think the simple fact is that "tapping in" to your cars electronics via an external device is virtually impossible. However, simply disrupting them is rather easy (HV pulses).

disrupting!? I remember it more like compleatly and utterly destroying the cars computer. kind of like generating a localized emp shockwave
