LOL...I hear ya, this Z actually started off its life as a chase car for mobile homes from AZ to California so the auto was a must for me, I did not want to have to be shifting all the time in California traffice. Now retired from its over the road duties it is slowly being turned into a show car, just got to get the thing done and painted. I love my Z and how It looks, I just try to have fun with it. So nice to me may be rice to you but I can live with that.

Thanks for commenting

 

I really hate to rain on your parade, but...........


As someone who has installed thousands of remote starts, I can tell you that that statement is 100% wrong.

I would go as far to say that less than 10% of the vehicles on the market with factory immobilizers require you to use a factory chipped key for the remote start.

You will need a factory key to program the bypass module, but only 10% of the time will the chip/key actually have to remain in the vehicle.

I've got a remote start on my 350Z that does not have a key, or chip in the vehicle.



Also, I'm not 100% sure on how that system works, but from what you've described about how it works I see a potential security flaw. I suspect that the system could be bypassed and the car stolen relatively easily. I may be wrong.....

I'm not going to get into more details than that on a public forum, but if you or someone who represents the company designing this product want's to contact me, feel free. I have a possible solution that would make the flaw that may be present pretty well disappear.


Don't get me wrong though... I LOVE! This idea!

 

All you would need to do is find and take the module housing the rf chip and place it in proximity to the ignition. Take the cut key in the ignition and turn the car over. If the factory alarm was armed you could always take the key out of the ignition and disarm the factory alarm by using the key to unlock the drivers door. Bam, car stolen.

 

I had a different way than that, but that's an easy one too... There are ways to do this system without an RF chip even in the car. You'd actually have to modify wiring to steal the car. Depending on how they're doing it, there is a good possibility that I could entirely eliminate some of the primary wiring that would be easiest to modify to steal the car from the system entirely, making the car significantly harder to steal.

Another thing to consider, but I've never actually tried it on my Z so I'm not sure: A lot of cars will disarm the factory alarm when a key is put in the ignition. Or in this case, I wonder if the factory alarm is actually even fully arming, or is it only locking the doors with the key in the ignition. Either way, I can think of a solution to this problem as well.

There are a LOT of things to consider with a system like this. I'd love to have one in my car, but there are a lot of "I wonder if they thought about that?" questions in the back of my head.

I've been thinking of designing a system like this for a long time for myself. Really I've got it figured out, I just need to find a "pretty button" to work with

 

Very true. I used to be an installer as well. I would imagine most cars would need to see a combination of the keysense wire and the RF chip for this method to work. The Zs factory alarm only disarms from the keyfob or at the door lock with the actual key. I'm pretty sure you have to pulse the unlock wire when installing a remote start on the Z. It's been a while since I did mine.

 

Actually, on the few cars that still use an RF bypass and aren't done through data, very few need to see keysense wire to start. You'd think more need it, but very few do.

You are correct on the unlock wire pulse to disarm. First pulse disarms factory alarm, 2nd pulse unlocks doors, steady ground pulse will roll down windows.

I'm surprised that the key in the ignition doesn't disarm the factory alarm, on many cars this does. I wonder if key in the ignition, and powering the ignition wire (turning the key) would disarm the alarm..

I'm going to go take the cover off the car, plug the battery back in, and play with the factory alarm for a few minutes because I'm curious now

 

Lol. Let me know.

 

ONLY key in the ignition does NOT disarm the alarm.

Key in the ignition, and power to the ignition (turn the key to run) DOES disarm the alarm. This may be the combination of the two that does, or it may simply be the ignition wire getting powered that does it.

Mind you I did not see if the alarm would arm with the key in the ignition. But the fact that it does not disarm with the key in the ignition I would say there is a good chance that the alarm would arm normally even with the key in the ignition.

Well, at least we know that the key in the ignition does not disarm the alarm. That's a good thing for their system, we still have full functionality of the factory alarm.

 

Sweet good to know. Thanks for the heads up. You must have quick access to the wiring under your dash. Mine is very neatly hidden and tucked away.

So technically if your to lazy to run wiring through the molex you could use a relay triggered by the disarm wire on the RS to power the ignition. Right?
Edit: Forgot that the key had to be in the ignition. Wouldn't work.

 

I didn't actually go to the wiring to check this. I just turned the key to the ignition position.....

The relay triggering the ignition would probably work to disarm the factory alarm. The way I tested it won't tell us for certain if it was BOTH the key and ign wire doing the disarm, or ONLY the ign wire doing it..... I suspect, since the key alone didn't do it, that it's the ign wire doing the disarm. To know for sure I'd have to actually get to the wiring to test, I'm not feeling that adventurous tonight.

I suppose for the disarm you could get away without going through the molex into the doors and just pulse the ign wire. Completely pointless if you're also doing keyless entry though since you're already there to do the keyless.

 

Yeah the module I used was the xk07 if I remember right. That was before the current models that can lock/unlock and disarm all over data. So the only option you had for everything to work correctly was to go into the driver door module.

 

I stand corrected on that,thanks for the info, its been a few years since I have been in the install business and I have not been keeping up to date on the bypass boxes that are out now. As with any security system or system of this nature it is useless if the installer does not install it properly. You should always hide all components as well as you can so no potential thief can find and access any part of the system. I make it a point to not install the brain or any other component in the dash under the column, let's face it, that's the first place that anyone will look. Installing an alarm is like installing a low jack system or a product of that nature, sure it will allow you to get your car back if it is ever stolen but that's only if the installer did his job and installed it out of sight. What good is any system that a thief has easy access to. This system does piggy back your alarm and keeping the cut key in the ignition does not effect the factory alarm arming or disarm. All Acc power for the car and key sensing wires are cut and ran through the brain of the unit, so leaving the cut key in the Acc position only allows for the wheel to unlock.

If you take you time and install the alarm properly with all components out of sight a thief will never find them. Plus not many thief are going to spend the time in your car with the alarm going off, lights flashing and horn honking to rip into your car trying to find a key end in a bypass box, then take apart the column to see if there is a key in the ignition. As with any alarm system it is only as good as the installer who installed it. Get creative with the install and you will never have to worry about a thief finding anything in your car. When I install an alarm I run all wires with the OEM harnesses that run through the vehicle and the brain and bypass box are installed else where in the vehicale so you could never even trace my wiring to the brain or bypass box.

These system also come with a plug that plugs directly into the back of your ignition cylinder and then the OEM ignition plug daisy chains into the plug that comes with the system, so no more cutting and tapping ignition and starter wires to install. It really makes for a lot easier and cleaner intall. Looking under my dash right now you can not evem tell the is an alarm system installed.

I can send you over the install diagram if you would like so you can see the level of difficulty for install and how to hook this sytem into your vehicle.

 

No problem, pm me your email address and I will send you over the wiring diagram.

 

I PM'd you my email. Send me any installation materials/pics you may have. This has got me really curious.

 

Sent

 

i have a question which might make me look stupid but, if your driving and you accidentally press the engine stop button will the car turn off, or does the brain also tap into the speedo so that the car only stops when the car is at a complete stop. Im interested in this system and i have a manual so i would imagine that the car would only turn off if you have the parking brake applied. If you could pm me the installation guide for a manual z so i can better get an idea of how the whole system works i would really appreciate it.

 

No problem, I will send it to you. Both the DW-Tech touch button system and ST800 smart system requier the vehicle to be in the park position before the system will initiate the starting or stopping of the engine. In a manual vehicle you would as you said run the park sensor wire from the brain of the system to the e-brake wire so it will only start if your vehicle has the e-brake applied.

The ST800 does have a speed sense wire that can be hooked up when installed to allow you to have the doors lock when the vehicle starts to move.

 

Do you have anymore information on the push button itself, the wiring pin outs for the wire harness for the button etc?

Any ideas if the button is available for sale separately?

 

The button is not for sale separately at this time, it only comes with the start system...Sorry

 

Where the hell do you find this ?

Auto something ? is the site right ?

I got a 2008 Z manual located australia..

Dont mind the cut keys thou

im installer my self

I got a viper on my Z its boring ..

ST800 would be a new experience.

I know how it works ..

Could you send me the wiring diagram over asap ? dimmotors@gmail.com
