I have a unit coming soon that I am going to trial in my GTR, gives you tracking via GPS, contact via GSM (2g), and gives you the ability to control aspects of the car, such as locks, ignition, etc.

Will be pretty cheap, but I want to tinker with it before I go advertising it.

B.

Is there anything else your device can do, which can't be done on the GPS GSM unit available on the SAU GroupBuys section and EBay for around $280? This may be an easier option for others, which wont cost much more by the time you get all your different components together.

I think the only difference is how the unit arms (via polling bluetooth) - the GPS GSM unit sounds great though. In truth, if I had found such a unit about 12 months ago when I first started toying with this project, I probably would have just grabbed one of those :rofl:. I only developed the software because I couldn't find something that didn't have an annual monitoring fee.

However the price can't be beaten, the Motorola phones are cheap ($40-$50 second hand these days), so total cost would be in the order of $120-$130. I was also having a look to see if there exist bluetooth activated power relays (so you could perform remote commands on your car). Sounds like the device mentioned in previous post might have that covered, would be excellent if the price is right.

Just a quick question, I have ordered the Globalsat BT338 GPS reciever off ebay, and the seller told me that they don't sell that model anymore, they now sell the BT339 model, would you know if this will still be compatible with the motorola l6 and the software that you are using?

Should get the GPS reciever next week, and also should get the Motorola L6 this week( from ebay $45 incl. freight :rofl: )

Will get it all setup up when i get all the stuff, and will let you know how it works.

Thanks for the hard work in putting everything together.

Can't wait to install it and put in my new R34 1999 Model GTT.(Imported June 2008, first owner)

see www.nagoyamotors.com.au for great deals on nissan skylines, recommend this dealer to anyone.

Just started testing the unit.

This is what I currently have:

Motorola L6, HP BT308 GPS Reciever(Using for testing before i get the BT339 reciever)

Software all setup and installed in corelet mode.

I tried it at work, and i got one of my collegues at lunch time to go somewhere and call me when they stopped. I setup the resend message time to 3min. As soon as my collegue started driving around 2-3min later i got a meesage with the coordinates. I started geting corodinates every 3-4min, when he called me i did a ping, and told him where he was, and he said that its correct. So im happy that it all works great.

Will install it in my skyline very soon, and see how long it will last.

I recommend to get a vodafone prepaid sim, and get the 365day plan. No need to recharge for a whole year, only when ur credit goes low, and you can recharge online, no need to touch your phone. Plus you can check your credit online too which is great.

Thanks again for a great DIY car tracking tutorial. :P

One thing that I would like to see is if the software can also send a speed data. Is this possible?

Plus if the GPSremote software can be written to work with iphone.

:kiss:

Will let you know how i go with the install in my skyline.

Hi good to hear it seems to have gone smoothly, were than any bits of the install guide that had you confused (felt needed more detail?). The BT339 should work fine, I'll be interested to hear how it goes.

As an update, a little after 3 months I got the dreaded "GPS tracker offline" from my car :ermm:. There's not much I can do for the BT338/Motorola L6 combo, I can only hope newer models fix this problem. In the meantime I'm content to reboot the GPS unit every 3 months after getting this notification :(. The most important thing is that it never goes offline without you knowing about it, which is what happens currently.

One thing that I would like to see is if the software can also send a speed data. Is this possible?

Yeah it wouldn't take much to parse the speed information sent out by the unit, I'll note it down and add this for next release.

Is there a way that we can install .jad or jar files on the iphone??

I need to install the GPSremote java software on my iphone.

I'm pretty sure the iphone cannot run java applications, unfortunately this is the only platform I know how to compile on mobile phones. I recall the iphone can be left in bluetooth discoverable mode, so at least it can be used as an arming device no problems. The GPSRemote application is *really* basic, it simply sends an SMS message on a specific port (for example, sends sms to number '0123456789:1111'). If you can find out how to get the iphone to send messages on a port, I can give you details on how to use it to perform remote queries. Maybe the default message client allows this, I just know the Motorola won't allow you the use the : character in the phone number field.

So far so good, all hardware installed in my skyline and working great. The only messages I've been getting so far is the Battery low message, I think this is because the battery might be getting old on the Motorola (Bought it second hand from ebay), plus I get this message more frequently when it is a hot day.

Could you please let me know the details on how to send messages on a specific port. I will try it on my iphone and let you know if it works.

Will be waiting for your next release with speed info. :P

Been a while since I've checked in on this thread, but a while back I packaged all the source code up and provided comprehensive instructions on how to compile the source code. So if you have basic to intermediate level programming, you should be able to compile (and tweak/update as required), for newer model phones.

I used this succesfully for 1-2 years, main problem was when I went on holiday for a few weeks, my car battery would go flat if I forgot to disconnect it all.

only works in areas of good cell strength, right now Im on to the TIO for unresolved cell site problems in my area. shared between two telcos. line of sight , 500 meters from the tower you can only get 1 bar tops of signal, outside !!!

near the beach, no signal due to wave refraction and salt refraction in the air. the thing drops to emergency or no signal.

this is in the adelaide area not whoop whoop.

other times you get signal propagation to a cell tower 20 km away and no ability to triagulate from the tower, since it can't see your close in towers ? so its not a perfect solution but better then basics

be easier if people didn't steal cars here but thats asking to much ? lol

    • Stock ECU (or more accurately stock tune) absolutely refuses to go over 10psi and behaves like you have seen. The Nistune is the same if it is the stock tune. If the Nistune chip has been tuned, the resulting tune could be literally anything for any combination of parts. The Nistune just makes the stock ECU Tunable.
    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way.
