    Thanks a bunch to @Patton250. He was willing to test my ALP setup against the Dragon Eye. Unfortunately we saw some punch throughs on left/right/middle. We verified that the configuration is ok, as it was able to jam an older laser gun consistently. So I am guessing, my sensors might not be placed correctly/efficiently to jam the Dragon Eye. I do have the TX plugged into F2 and the left and right (regular) sensors in F1 & F3 with GPS and the HiFi module. I don't have sensors for the rear. All sensors are mounted with a 90 degree angle to the floor. The config was setup for unlimited and was running the app at proper speed so it was in defense mode. The ALP was triggered with the Dragon Eye, but was only able to jam at distance for a short amount of time but ultimately had punch throughs at right/left/middle.

    I have attached 2 pictures from my setup and marked up the distances of the sensors (one front and one side view showing it sticks out from the grill). Let me know if I should take any other measurements to make it easier to trouble shoot. I followed the exact recommendation from the ALP website for the BMW 3-series (regular sensors mounted vertically and the TX horizontal).

    Thanks!

    Mount the TX here in the red. Pull it out a nickel's thickness.

    Take the RX sensors and move them in 1 slot

    The placement looks pretty good, that spacing should be decent. The two things that jumps out though is that the outer receive heads have the receiving diode right next to the shiny trim ring that surrounds the grill and that last slat is more recessed than the one right next to it which is also shiny, wonder if you could be getting some reflections that could be hurting the performance a little with the dragon. I wonder if you moved the head in one slat and put the bubble up at about the same height if that would help as you would have the receiver more out in the open and farther away from that lower shiny trim ring.. Not a dragon expert so I will let them jump in with their thoughts...

    Try what I've suggested. I've been successful with close to a handful of BMW grills and JTG. Let us know!

    BMW Front.jpg I would move the outer sensors in 1-slot and get them LEVEL straight up/down, you have them leaning over!

    What's the trick to keep them from leaning over? I'm having the same problem with my E60.

    Too much chrome. The TX sensor is probably reflecting back in to the RX sensor and confusing the system. It's in the recommended spot base on alpriorityusa's website, but either needs to stick out further than the chrome or you need to plasti dip the chrome. Just my .02 cents. Raising it, as Andrew21 recommended, is an option that may move it far enough away from the chrome interference.

    Not sure, but it also looks like the RX sensors are pointing outwards as well. Hard to tell from those pics.

    Use Sugru to mount them. You can build it up on one side to set it straight. When it drys, it'll be set where you left it. I think it's much better than the mounting brackets and much less of a hassle. It's also much easier to remove and doesn't damage anything.

    Let them lean. I never fixed it on one fo the BMW's and it was JTG. As long as they are not at a 45 degree angle, you're good.

    Had good results from this believe it or not. As long as they are around 25-25.5 inches you'll be okay

    I don't think the issue is with leaning sensors... After all, the photosensor is round, so are the LEDs ;) I'd say moving them all slightly forward, out of the grill, might help more (if the issue is caused by chrome trim).

    I have a similar front setup on my 440 but I noticed my RX sensors are flipped. I tested with Andrew and no punch throughs. So maybe try flipping them so the bubble is on top. Pic attached.

    Thanks for all the input. I will take all of the above suggestions to improve the setup.

    Black (non-chrome) grill is ordered and new ALP brackets have arrived.

    I will report back to this forum with the results.
