Units like this need to mounted on the windscreen - not a big deal these days with every other vehicle having mobile phone and/or GPS units mounted there aswell. There are more advanced ones that use sensors on the dash/back window/front grill, but the unit hides away.

You can modify a radar detector to become a detector-detector - this is what the police use and it provides a signal direction too. Most decent units have a shut-off that once it acknowledges that it is being tracked, it will stop detecting to avoid being identified. This obviously only works if there are other cars around. If you're by yourself, it won't matter.

It will pick up mobile radar no problem as they tend to operate continuously and as someone said, the signals bounce off anything/everything. Speed cameras are a strange one - some operate continuously (easy detection), some operate sporadically so you might think its a false signal and ignore the alarm (shopfront motion sensors for automatic sliding doors can set some models off). Lasers are difficult - they hardly reflect off other vehicles, and if it gets pointed at you, you'll be warned as your speed is recorded.

This is all just general knowledge to answer some questions, not specific to the model being sold here.

Just curious, would radar detectors detect Highway Patrol cars jsut driving around?

Reason I ask is that I've been told some HWP cars have radars in their car to detect speed and is mroe or less constantly switched on. Any truth in that?

After all of this talk ,are these things any good?

Or, if caught you are in more trouble than just the speeding ticket????

Is there a product out there that gives us a fighting chance if we slip over the limit, without being fined for having a radar detector in our car.

If they have to put up signs saying there is a radar speed detector up ahead , why are we not allowed to have something to detect them ??????

Before you shoot me down, "do not speed" and then "no problem" shit it is hard to stay within a 5k limit with a modern car where 1 or 2MM on the peddle is about 5 kph :w00t:

I have done lots of dumb driving over my life in cars that should not have been on the road and today would be scrapped , F, cable brakes were fun :w00t: the car could go twice as fast than it could stop :stupid:

I do 3500kms per week, I use one and cannot recommend them highly enough, yes they will go off at certain business/servos. yes the police with a handheld need to be locked onto your car for it 2 pickup laser alert, yes it will pickup highway patrol cars with there radar turned on before u see them and yes it will pickup flash for cashes parked on side of road. good luck with sale, good price :)

i just got a speeding fine, he said his laser showed i was speeding, so my question is does this unit tell me if a cop has a radar with a laser before i get in range of it?

Uhh, no.. by definition if you're not "in range" then how is the detector supposed to detect the radar or laser signal? a signal has to actually been seen by the device to be detected. with the laser speed measuring devices cops use today, you will have only ~1 to 2 seconds to drop your speed if you're speeding before they lock in the detected speed, in other words not enough time. Another approach would be to attempt to "jam" the signal by diffusing the laser with noise on the same wavelength buying you another 4-5 seconds to slow down... but not all of these have success in actually working as advertised, and are also illegal. Also note that most detectors are easily detected by police scanners because they emit a signal which can be identified - the only one i know of that claims is not detectable is the Bell XR/STi.

    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
    • Yes sir am asking is there possible way from aem tuner from wiring pins 
    • Have you checked cam to crank timing and confirmed balancer marks are correct?
