Cool! Thanks.

 

Holy crap throw a link to this **** into the FAQ

 

I just fell in love again! that just made my car ten times sweeter. Holla! is there any way to change the digital tach in MPH instead of KPH?

 

I think the tach is measured in RPMs

So does this reset everytime you turn the engine off? If not how to you change it back to the normal display?

 

Bruzum how do you like that Veil Laser "Countermeasure" from your experience dose it work?

 

I haven't actually been hit with a laser since I've applied it. It's too cold for the po-po to stand out in the cold. But I saw a video of some pretty extensive testing that actually included a black B5 Audi S4. It effectively blocked a laser reading from beyond 800 feet. The point would be that my laser detector would go off past 800 feet and give me enough time to correct my speed.

A friend of mine has a 350z with VEIL and a laser jammer. The jammer is supposed to work inside the 800 foot range down to 200 feet making him really hard to pick off with a laser. But it cost him around $650. He's hardcore about going fast and avoiding tickets. Hasn't had a speeding ticket for 18 years.

Overall it's given me a little more confidence. I find that my fear of someone pulling in front of me at the last seconds keeps my speed in check more than fear of a ticket now that I've got the VEIL. The con is that the headlights appear tinted from 20 feet away. Any closer than 20 feet and they look dirty. Luckily the headlight washer don't damage the coat.

 

to get it back to normalyou just do the same you did to turn it on, so you guys tried this and liked it? I will wait for 2k to say something before I go invading his FAQ haha

 

wow very nice find.. im going to try it later tonight... i wanna see the speed in kmph.

 

hmm, how do you change from mph to kmph?
