LI Reliability Issues ?????

[KnightHawk]

I will admit that the LI tester is a nice toy to have but it will not tell you everything. It will tell you if the LI is detecting and alerting to certain gun but will not tell you if it is jamming properly. If you look back at CFL#5 I believe it is, you will see that we had a problem with the driver side head of my LI. I was getting P/T at 500-800ft on drv side. It alerted to every gun properly but was not jamming on that side. After Elvato looked at the head with IR camera he believed possibly moisture was in the head. We replaced the head and P/T was cut in half but still remained in the 250ft range. Last time I got together with Cbr and Elvato we tested my LI against the Stalker and was still getting P/T. I'll admit it was short...Like 50ft...But still P/T even after the change in heads and realignment. I also tested with the ProLaser3 one other time since then and P/T was still around 200ft. So to some it up...The tester is nice to have for detection but don't count on it 100% because detection is only 1/2 of the solution.

Do you think it could be because of the type of vehicle you tested? Possibly needs not just realignment and replacement but also moving the heads closer to your headlights? If I understand correctly, you were using the ford escape which does not have good aerodynamic characteristics. I think the only way to tell is having the same set up with a different unit and ford escape. If you compare your ford escape with the rest of the group, there will be some degree of disadvantage on your part resulting to some PT's.

I wouldn't say it was placement because they are in the grill less than 8" from headlights and it was JTG on passenger but not drv side. If it was placement or aerodynamics it would IMHO be the same on both sides..Last time I looked the drv side looked just like the passenger side as far as shape goes...HaHa

Also I will correct myself..I said P/T was around 800ft..I just checked and the highest P/T was 571ft..And don't take this as a put down to LI because it isnt.Those were the best results I had to that date after having the PASS for 2 tests. This is only pertaining to the tester comments.

Still a ford escape.
You know 1-2 inches of placement can make a difference plus drivers side headlights are angle slightly to the right in most vehicles to minimize glare effect towards drivers driving the opposite way. I think sticking on your 8 inch distance does not necessarily mean that's the best placement. You still got to do some trial and error setups. What I meant about aerodynamics is that, it has less reflection say on a honda accord than a non-aerodynamic vehicle like the ford escape and headlight designs are not the same in every vehicle. The fact that you change head and still gets some PT's require more testing and placement trial and error.

Anyway, just keep testing MH 'til you find the best placement.

Point taken!

i will talk to "LI-Tester" designers wich is not LI tester but "Speed Lab" product to implement a simple receiver to tester and one green "LED" that will flash when pulses from jammer are received.. :-) so you will know it is RX-ing ad TX-ing... how about that? :-)

Very nice. I just use my cell phone camera to see if my jammers are firing. I learned that from you Ivan.

That would be awsome!

The information suggests a substantial failure rate of LI units. (Including new revisions)

I have recently purchased a LI 7.06 with 8.5 heads.

It's not yet installed and seems to be funcitoning perfectly well on the test bench using the TV remote method on each head.

Very nice. I just use my cell phone camera to see if my jammers are firing. I learned that from you Ivan.

Awesome bit of info' there djrams80, thanks

I have tried to capture them firing with two different canon digital cameras in a dark room and only managed to get a faint image, but the nokia phonecam shows it up really well.

Now I have the utmost confidence with my kitchen table install.

An added comfort is to have a laser jammer tester that is fraction of a cost of a laser gun for testing your head periodically. Very handy and you can test your heads with different pulse rates. IMO, a MUST for LJ user.

Already have one......................

^ Exactly.

Very nice. I just use my cell phone camera to see if my jammers are firing.

^ And that's very logical, too.

But still, it does not tell you that the outgoing jamming algorithm is a proper match, which, I hope, is what Ivan means to say here:

^ Ivan, is it cost-feasible to have such a tester that would identify and notify as to the "proper" response output algorithm for each of the threats simulated by the SpeedLab product?

I've got their v1 version, bought through the "group buy" here via the now MIA member jammer84_03, and this would be an awesome evolution of that product!
