Really disappointed at this point.

I retested my ALP install and the front seems to be doing well. JTG 95% of the time with occasional PT at 110-150 ft.

However, the rear is a different story. I get IPT when shooting at the license plate. I figured I might have had issues on angles or the extreme sides of the tail lights but I get IPT when shooting the license plate straight on (well about 5-10 degrees as I was on the sidewalk) which is directly between the two rear heads.....

Speed was 30-35. Sunny. Temp ~ 45 F

We waited 2-3 minutes between shots to give time to reset and the lights from the ALP were as expected.Tested the front to confirm the ALP was active as well.

It detected but seems to do nothing as far as jamming.

100% IPT over 14 runs

Anyone have any suggestions?

Do you have a Tx on the front and not back? I’m no ALP pro but what’s the minimum required distance as well?

Edit : nevermind the distance thing. You said only the license pate and they jam well when you hit the lights ?

TX on front.

On rear they do not JAM anywhere. I pointed out the license plate as it is directly in the middle of the heads so I would think there at least it would jam.....

Add a TX at the back and you'll be golden.

An expensive option when I was told that 2 sensors would be plenty. I could understand that option if I was talking about the tail lights dues to distance, but dead center?...If a Tx is required then the premise that 3 regular sensors on the front is enough could not be true either.

Fundamentally it is marketed as not needing a Tx sensor except for specific circumstances. Shooting dead center within 12 inches of both heads should not be one of those....If it is then the marketing needs to be changed to always require a Tx sensor against dragon eye......

if I have to sped another $350 on a yet another Tx sensor, I'll just buy a TMG and be done with the ALP.......

You’d definitely be better off just adding a Tx head than going to TMG to solve your punch through problems...

I know you’ve had some experience with 2 standard sensors in the back but is this CM IPT situation really the norm? From what I’ve seen 2 sensors are usually strong against an on axis CM shot.

@Starz26
Can you pull a stats file for us and post up a screen shot?
What distance are we talking here? 1000 ft PT is different than 200ft PT.
How far apart are your 2 sensors?
Have you tested the rear in the past with different results?
Who did the install? Are you sure everything was done correctly?
Are you sure the config file is correct? Try reloading a fresh config file.

I get that. But if it takes a Tx sensor to solve an IPT between the two standard heads then I feel like I was lied to. This is the most basic thing. Nothing fancy, no weird angles. Just a straight shot between the heads well within the distances recommended.

I was hoping that there could be another possibility other than invalid information being provided....and a different fix than spending more money when I was told that it was not needed and 2 standard would defeat the dragon eye (at least in a basic situation)

No stats file as I do not own a control set. Integrated with Radenso
Punch throughs all under 1000 ft - Straight flat road in my neighborhood. did not try really long shots on rear
Sensors have 20.5" between them from inside edges
Reputable installer. Was tested by Radenso with their gun and was told it was JTG although it was only test 1-2 times as most of the tests focused on the front and it was raining pretty good. This test was ~ 3 weeks later with my gun
I did that prior to the last 5 runs as I thought maybe that was the issue. Remember the front JTG though

I would double check to make sure the rear heads are actually firing before going down any other route.

How would I check that? I know they are alerting but how would I check they are firing?

Ya something seems funny here for sure.

A stats file would be great if you can somehow get one with Bluetooth or temporarily plug in a control pad?

Does it jam with ECCM not active?

You can check the heads are firing back with certain phone cameras that don’t filter IR light. If I recall, front facing cameras often show IR light since they are lower quality and have less filtering. Basically you just need a camera capable of showing you IR light.

I have an iPhone 7 not sure if it will work also kinda hard to capture at 20 mph right? (when they become active)

I will try shooting with ECCM inactive tomorrow.

What is the firmware on the ALP? What about the Radenso?
Any recent firmware updates?

ALP and Radenso were updated within the last month on install. No idea the version on the ALP as it is not displayed anywhere but the Radenso is the latest...I tried to update the firmware on the ALP again today but it would not do anything. I assume because the version was the same? It reloaded the config just fine. (Yes a clean USB each time)

Its all over this forum, its a given--for the Dragon you NEED at least 3 reg heads or 2 reg and 1 TX---nothing new here!!!!

I don’t believe that’s true. On axis CM shots can be JTG I’m pretty darn sure. I wouldn’t suggest running duals against the dragon in the wild due to compromised off axis behaviour but 3 sensors is not needed for easier shots. Adding that 3rd head certainly turns the tables in your favour though, I’ll admit that.

Depending which Version/Firmware of the DE Lidars (DESL or DEC) you may be able to get some protection with two heads. (Pm me if you would like to discuss the version). Also without knowing this yet, I would flip bubbles in and move the Rx sensors closer in. There is too much space between the two for DE protection where they are currently. Looks like your around 20-24 inches apart where they currently are? Thats too much space with only 2 heads which is leaving your back end extremely vulnerable. I assume you were getting Pt's on the taillights as well?

Edit*
And this is how you pull a stats file on a standard control set as well. Just in case you would like to send one of us to make sure your set up is correct. Though i think it is seeing as you are alerting, but never hurts for a second set of eyes.

Connect USB flash drive to the USB port in AL Control Box, or in USB extension cable,
Enter Yellow Menu by long press of MENU button,
Press NEXT 7 times then press ENTER (you will enter Service Code sub-menu and LED will turn white),
Now Press NEXT 2 times then press ENTER and wait for sound sequence to finish,
Again Press NEXT 2 times then press ENTER and wait for sound sequence to finish,
Once more press NEXT 2 times then press ENTER.
AL system will store your present settings and use statistics to USB flash drive by creating a file named config.alp. If file storing was successful the system will alert you with a short blue LED light. The AL system will exit yellow menu after a few seconds of being inactive.
Connect this USB flash drive to your computer.
Click Browse and find the Config.alp file on your USB memory drive and press Upload.

Sounds like a config issue. I’ve run two RX heads on the back of an Infiniti g37s and a Nissan 370Z with pretty good results against det eccm. I agree the heads seem too far apart. In addition to checking config, I’d also check them with the edge of a long level to make sure they also aren’t aimed out instead of straight ahead.

Also, have you tried calling Tom at BRD?

P.s., need to maintain some cleanliness in the back for protection...road salt and dirt caked on the heads will have a negative impact on protection

The way ALP behaves with Dragoneye is different that with other guns too with respect to which heads listen and which heads fire and the thermal management for transmitting diode which can be a limiting factor in the dual setup. With two heads there are some limitations as to what the system can do. It is dependent on which DE version its up against too, older variants could be covered against two heads, new ones probably not as well.
