i think its broken i get false LIDAR every 5 min

any easy fix to this ?
i don't have time to send it in but i may have to

Do you have any laser emitting cruise control devices? I don't think the speed 3 has that, but you know better than me. Also, try turning off laser and see what happens.

Did you buy the unit new?

Also, looking at your install what are those 2 round things that looks like they are attached to the radiator?

no i don't have laser emitting cruise control
and thats not my radiator lol its my front mount inter cooler

and some Hella supertone horns for deaf ppl

MPS, where are the pictures of your install? No photos seem to show up for me.

EDIT: Never mind, I just found the thread.

Hi MPS,

Your Madaspeed 3 is a really neat looking car. I love its dash!

Anyway, onward to your STi-R's laser falsing problem. I will list things in the order to check:

-- If your STi-R is laser falsing with the car engine turned off:

1. Temporarily disconnect power to the STi-R by simply removing its inline fuse.
2. Pop open the hood and locate the radar antenna cable's inline connector. This inline connector is approximately five feet back along the cable from the antenna. Unplug this connector and then plug it back in once or twice, just to be sure that there it is making a good connection.
3. Check the ground connection for the STi-R's interface box. Check the ground spade to be sure that it is secure under a bolt, and check that the wire crimped into the spade is well crimped.
4. Similarly check the power connection. If the power connection is tapped into the cigarette lighter power wire, instead get an add-a-fuse at a local automotive store and tap the STi-R's power into a 15A to 20A terminal in your car's fuse box. The heavy gauge wire for 15A to 20A terminals runs straight to your car's battery, usually through a separate fusible link under the car hood. The reason for getting STi-R power from one of your 15A to 20A fuse box terminals is that the heavy gauge wire will be free of electrical noise.
5. Reinstall the STi-R's inline fuse and see if the laser falsing has gone away.

-- If your STi-R's is laser falsing only when the engine is running:

1. Turn off car engine and then do Steps 1 and 2, above.
2. Make sure that the radar antenna cable doesn't pass close to any car horns, ignition wires, ignition coils, ignition modules, or ECU (car's computer box) under the hood. All of these items are potential sources of either electromagnetic or RF interference. Keeping the radar antenna cable a foot away from these items usually is sufficient.
3. Reinstall the STi-R's inline fuse, start car, and see if the laser falsing is gone.
4. If the laser falsing still persists, then try all of the steps described for laser falsing when the car engine is turned off.
5. If you still experience laser falsing, then get a snap-on RF choke from Radio Shack, loop your STi'-R's power cable through it twice, and snap the choke closed. This choke should stop laser falses caused by excessive car wiring electrical noise.

that is good info
but we have 3 cars that are the same and i did all 3 installs the same way
and only mine is having this problem but i will go over ur steps

Thank You

you bought 3 STI R's? And also rest the unit, first before you try anything else.

**MPS** · 10-06-2008, 08:58 PM

where is the reset ?

**YTCD** · 10-06-2008, 09:02 PM

i know how to do it on the sti, but not the STI R, let me get mem or somebody in here to help you. I'll private message them

**YTCD** · 10-06-2008, 09:12 PM

nobody is online right now that would know. But try this, should be the same

Turn the unit off, then press volume and mode and hold it down, then press power. Then release all three.
