Hi,

I'm having problems with my alarm. It doesn't register my key presses, mainly disarm. I have to press it many times before it will disarm. I've tried resetting it and reprogramming the remote. That hasn't helped. Using the valet switch to disarm it still works. Anyone on this forum in Victoria who can service these alarms? Getting very annoying when I have to stand at my car pressing the remote over and over again.

Hey. its a viper what else can I say. They are only useful as sinkers when you go fishing! Chuck it out and get e real car security product.

thats a bold comment, directed electronics make some of the best products on the market !!!! if you have the talent to wire them up right ?, failure rates are extremeley low which is why they have a lifetime warranty on most (not batteries ) parts , 99% of the time bad wiring job or remote thru a washing machine is the issue.

take it back to the place that installed it ??? they would sort it out quickly

first guess, no antenna connection or its been cut/taped on steel after someone worked on the car ,which = no range on remote, second, lost programming by fiddling around with a few things with the key on , is it a new remote??? changed the remote or car battery lately, remote battery is it in the right way?

a newer viper won't unlock if it see's mutiple alarms in close proximity being armed or disarmed. the upper models will vibrate or chirp the transmitter when that happens(anti code scanning protection)

sometimes the on off button gets mashed inside by you pushing on it too hard or crap in your pockets, if it can be unscrewed

have a look at it on the inside , the little pin behind the button , mushroomed ??? or missing ??

does it work by pushing the little rubber button with the case off? if so buy a new case or remote

if you have two remotes try the other one??

if not does it have any error code beeps or flashes ?

might be a scrambled brain if you jump started the car ? but if a DEI Authorized pro installed it ?? DEI will swap the brain no fuss most of the time

Sounds to me that there are alot of things that could go wrong with a Vyper...Not to mention the countless emails over the past decade for the same type of problems, but don't worry Brant Alarms are still winning in the category for most unreliable car alarm.

I got someone on this forum to install it. I've tried a second remote so it's not a remote issue. I just need someone who works on alarms to have a look at it for me.

change the batteries onthe two way unit and make sure its set to user 1 on the remote. that is 90% of the issues with those. the otehr 10% has to do with antenna placement and install.

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.

      Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve.

      I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
