Interesting to hear that the almighty ALP has software issues just like Escort. The passion about this seems as high as the passion about JTK over on the Escort threads.

At least I can side with ALP’s justification for securing their intellectual property. Escort’s justification for not making AutoJTK a default does us all harm no matter what brand you use.

(3) Cost of the GPS antenna and GPS module. AL Priority USA sells the antenna for $59 USD, and the GPS module for $99. Both are required to meet the GPS requirement for using the Tx sensor.
Only the $59 USD antenna is required. HW 2 CPUs have a GPS port on them for a direct connection without the need for the RG (radar/gps) module. And HW 2 is required for the TX use to begin with. Still, an annoying added cost no doubt.

And just as useless. OBD2 Simulator

AL needs to follow the KISS principle. The more crap you add to your software, the more likely that some bug is going to screw someone over. It goes without saying that you shouldn't add unnecessary crap because there's absolutely no benefits to that and a lot of potential drawbacks.
That’s bad ass!

I had a feeling something like that was available for developers.

How easy would it be to get rid of it? Could they just do a firmware/software change if they wanted?

Only AL really knows. If they wrote the software for this "feature" in a sensible way, it should be as simple as setting or unsetting a flag. If they wrote the software in a not very sensible way, then who knows. Do you remember that ALP bug where users were selecting detect only mode and their ALPs were actually jamming? (I think this was about 3-4 years ago). That was the first "WTF" type of moment I had with the ALPs, as it should have been controlled at the very top levels of the software (generally easy to understand and simple with only very abstract stuff being called) and should have been almost impossible to screw up. And yet, they screwed it up.

This really reminds me of this programming project I did in grad school were I programmed some wireless sensors in TinyOS. I was actually trying to optimize the performance of these things if they happened to lose contact with one another and were no longer "in sync". The problem with TinyOS is that nearly everything is done in the interrupt context, and I remember there was a top level ISR which called a procedure, let's call it A. And then A would do some work, then set a timer to call B, which in turn did some work, and set a timer to call C, which in turn set a timer to call D, etc. Now if you were working in a higher level language, you'd see something like:
procedure ISR {
callA();
callB();
callC();
callD();
}

Want to remove the call to C? Just comment out that line. Then A, B, and D (but not C) will run, and in that order. Want C to run first, followed by A, B, and then D? Then just change it to the following:
procedure ISR {
callC();
callA();
callB();
callD();
}

Oh, but not in TinyOS. You literally had to go into the top-level ISR and change the call from A to C. And then you had to go into C and change it to call A instead of D. And then you had to go into B and change it to call D instead of C. It was crazy. Each time you were mucking around with stuff like that, you had the opportunity to screw something up. Like, I'd try to change one little behavior like running C first instead of A and the entire system would lock up because it deadlocked or something like that. Generally this might happen because maybe D was required to do something that allowed the system to keep running, and in changing the code in 5 different places, I'd accidentally removed D from the list of stuff that gets called when this particular top-level interrupt service routine fires. Or maybe I accidentally still had B calling C, and so what would happen is it would call C->A->B->C->A->B->... forever. And this appears to be how AL has written its software, given the behavior I've observed from it.

I see three main concerns here:

(1) Loss of signal could leave one vulnerable to hits when one is at or above 30kmph. Example: coming out of a tunnel where the user had been sitting in traffic stopped out of signal for a while.

(2) Even with full signal, there is an opportunity of taking a hit when accelerating from below the 30kmph limit, to above it. As there is a delay on the GPS speed readings, it’s possible to be hit right as you’re crossing the threshold and accelerating beyond it.

(3) Cost of the GPS antenna and GPS module. AL Priority USA sells the antenna for $59 USD, and the GPS module for $99. Both are required to meet the GPS requirement for using the Tx sensor.

A OBDII speed sensor may be a cheaper option, but likely only if it didn’t require a module with it as well.
very rarely i loose signal and when i do my system goes to armed automatic
i have it to turn on at 31 and is very accurate with my car

Germany has no speed limit on the autobahn and their death rate is about 1/3 of the USA for same amount of miles traveled. Also the faster you go the less time you are driving... which means less time for an accident.

It’s a myth speed kills. We need to start an organization to raise speed limits on a ration basis, taking into account of the economical benifits if less time on the road. Also less wear would occur on roads

Same experience here... It likely depends where that antenna is. Mine is on the dash right by the VIN plate with clear view of the sky. If your GPS antenna is under anything. Move it.

Mine comes active at 20+mph though @ivan911fl are you talking 31kph?

Personally I wish the ALP had designed the CPU to have a headphone jack to plug in an external speaker. SO many compromises are workarounds are necessary just to get dedicated audio coming out of it, either HiFi or BT. Having audio come out of the controller port causes conflicts with simultaneously Bluetooth and control pad functionality. With the NR DSP, for example, if I want lockouts, I need to run it with my phone, but then I get audio delays via my phone and, more importantly, my control pad / remote mute buttons no longer work for muting radar signals or locking them out. I personally hate the interface issues I run into that all stem from not having a dedicated speaker port on the CPU.

This GPS issue is a close second though and it's one thing I miss about my Miata when I could run without Tx sensors and thus any of this goofy GPS nonsense.

Irrelevant. People purchase ALPs to protect against tickets. There could be a road with a PSL of 40 that is perfectly straight, has no cross traffic, etc., on a clear day, and someone who is first in line at a traffic light looks to the sides to make sure nothing is coming, and decides to launch onto that section of road when the light turns green. That's not dangerous, but if he has a Tesla that does 0-60 in 2.8 seconds, that stupid GPS "feature" is going to get him a ticket.
.
It is actually not irrelevant, as being irresponsible and not using common sense one deserves a ticket. Besides if one isn't smart enough to check Waze and have a good look around for LEOs while stopped at the Light, than again said speeder deserves a ticket if they can't see the LEO 200 feet away especially since in under 0.7 seconds the AL Priority is already armed, if one selected 18MPH/30Kph, well before reaching the PSL of 40 and long before reaching 60 or above! AL Priority DOES NOT wait until the acceleration ends to arm, it arms at 18MPH, so your example is very flawed.

Nope, because the LEO could get 2000 feet away and hiding behind a tree or road sign, and it doesn't arm at 18 mph, it arms when it detects that the speed has passed 18 mph. Those two things are very different.

1) Almost no one uses Waze here, not enough population to make it feasible as a CM.

2) These are not marked (or even unmarked) LEO vehicles. They are maybe red Toyota Sienna’s with a photo LIDAR setup hidden inside. Or a green telephone utility box with photo equipment set up inside, and the operator parked around the corner a street away.

I’d bet I can spot a trap earlier than 99.9% of people out there, living in the most speed enforcement-dense city in possibly the world does that. And I still get surprised by them.

3) The PSL is 30... the same speed ALP is supposed to arm, IF the GPS registers it at that exact instant. Tickets start at 33 km/h. I’ve already had this cause me PT’s above 30 twice now. In my Golf R (and there are TONS of faster cars out there) just as an example, if I floor it from a stop, I can watch as the ALP LED often doesn’t flip to armed until I’m at 39-42. There is a delay as the GPS has to register the change before it arms. Which is why the limit needs to be removed or at least cut in half.

If this doesn’t affect you because you live somewhere it isn’t an issue, or your car is too slow, or any reason really - why add your pointless and ignorant comments? All of which are wrong?

Again poor scenario, as the LEO at 2000 feet is NOT going to be painting even a Ferrari F40 at 2000 feet sitting at a red traffic light. For again the system should be well armed before even reaching the posted speed limit as long as the owner selected a good GPS antenna location with clear sky view! Ones GPS antenna must be properly placed. My friend Larry Gandolfi has an ALP 2RX/1TX front/rear installed in his Ford GT and no matter how fast he accelerates the LED is always Blue before or right at the speedo hitting 20MPH. His GPS antenna is mounted in the open on top of the dash where it meets the windshield. GPS does not stop working/receiving signals simply because one is stopped, it is only waiting for moment to begin again to determine speed.

It shouldn't take until one is above the supposed PSL of 40, to "DETECT" the vehicle is traveling above 18MPH UNLESS one has chosen a poor mounting location for ones GPS antenna. If one is a Red Light Dasher, I strongly suggest mounting the GPS antenna with the clearest view of the sky!

If they are ALL Red vehicles it should be easy to spot then shouldn't it????????

Again if the PSL is 30Kph, and YOU know your system doesn't arm until 30Kph and you have chosen a poor antenna location, then YOU should know better then to blast away from a Red Light in a 30Kph Zone with a Red Toyota parked up the street, Dah!!!

This is NOT an ALP issue, this is a common sense issue! Just as one does not blast down a two lane highway at over 100MPH at night in North Carolina without a good Rabbit up front because nobody can beat 35.5 Ka I/O in a one on one encounter. Again Common Sense!!!!

No, I can hold my phone OUTSIDE THE CAR WINDOW and watch as the GPS doesn't register my speed until around 1 second AFTER I reach that speed. There is ALWAYS a delay. If you accelerate like a grandma, fine, but don't tell other people that it isn't a problem.

Bottom line is this: GPS requirement is stupid and technologically unnecessary, and puts people at risk.

And yet multiple people feel the need to chime in and pretend it’s not an issue, and defend AL’s use if it because....? They are actually software engineers for AL and don’t want to work? Makes no sense.

No. They used unmarked leased vehicles. I don't think you understand the level of enforcement we face here.

You missed the point entirely. They could be any vehicle of any make model or colour. Changes all the time.
My antenna location is front of dash under glass, just like your homies ford FWIW. Still delayed.
The real question is why are you defending the GPS limit so hard? If you don’t think it’s an issue, cool. You’re wrong of course, but lots of people have been wrong before you, it’ll be ok. Obviously it won’t matter to you when they fix it. But in the mean time, no one wants your opinion.
