What did you use to learn it?
And is there any way to 'wipe it' to start over again?

Today, messing with the device, I got it to rotate (randomly) the sensor data to all 5 wheels! None of the data changed mind you...just the position.

Also, ALL the software for this reads the USB device, not the TPMS. There is no direct way to check to see if the device is actually functional? i.e. can read the sensor data?
All the software tells me it's reading the USB portion of it, and the 'learned' data store on it...

Erm, correct me if I'm wrong here - you actually paid for the hardware and firmware - the software applications are all freeware, and not guaranteed to work on all different incarnations of carputers out there.

Maybe write your own application might fix the problem for you, or making use of different (proven) pc hardware that is happy with the mentioned applications.

As long as people (like you) realize that the plugin developers are doing this for free, and they are actually under no obligation to spend 100's of hours to test every possible combination out there.

Time you start doing a bit of reading through this thread, as most of your questions have been dealt with in the previous posts, ie, for example, how to clean the buffer of previous sensor's data, etc.

Enjoy. Sorry if I sound ****y, but to many guys just demands this and that, and it is not on, especially when it comes to guys that developes applications for free.

Enjoy getting it sorted.

I've been thru this thread...pardon me if I don't remember which page outta 50+ pages mentions clearing the buffer...

Maybe if you know you could tell me...which would probably be much more helpful than what you just posted...and I wouldn't have to keep going on with this rant...

I'm looking for help from the developers here...I'm only an end user, and know nothing of programming or even how the software works. I do however, know quite a bit about computers, and I've tried everything possible to make this thing work...to no avail, obviously.

As far as hardware, USB interface is a pretty standard, 'universal' protocol. And even if it were the controller, I've tried 2 separate hubs and on two PC's...
I've even used XP and Vista OS's trying this out...

Maybe the plugin dev's are writing the plugins for free, but I paid money, just like everyone else here, to have a working TPMS...and I'm outta ideas on trying to make it work...

Sorry if I sound *****y, but I'm at the end of my rope with this thing!

I think the TPMS doctor shows the raw data of the sensors in hex, don't know if that data changes with different pressures. Where do you have your unit placed at? Have you tried using a different antenna?

WuNgUn,

I am afraid, I agree with Mr Bean, who I can confirm is a very easy going person, and is mostly very willing to assist all with those technical issues when he is able to.
Most of the questions you ask, hasve already been asnwered earlier in the thread, and I guess he is asking that you should at least try to understand the issues been brought up and clarified before asking someone else to do your reading for you.
My suggestion is that you completely revove the software, and reinstall the latest version. Then start the learning process as has been described in the recent posts.
To do a complete reset, take a look at the image on Page 17, and in the lower left hand corner,, while holding doen the **** Key, click on ROBBY. That will display 2 switchwes. The MASTER, will wipe all settings and allow you to start from scratch.

Please be patient with these developers, who have no charged a cent for their efforts.

WuNgUn · 10-26-2008, 09:09 AM

I appreciate the help, honestly...
It's just really frustrating trying to make this work. I mean, driving to the local gas station 12 times playing with the pressures isn't much fun! And it isn't even the closest gas station...the closest gas station wants 50 cents to use their pump!

I went thru all 53 pages last night, twice, searching for 'buffer', 'reset'...
I couldn't find a SINGLE post about resetting the buffer data! When I'm told to do the foot-work myself, I don't have a problem with it. But I really don't appreciate being led on a wild goose chase...

Ally, your post is censored...lol
What 4 letter key would be censored on the forum?
**** key?
**** key?
**** key?
lol
Not 'home' key? Or CTRL...

WuNgUn · 10-26-2008, 11:18 AM

Okay...cleared the data...
Didn't want to learn after that. Maybe my receiver is dead? I noticed one of the traces 'lifting' a bit with all the handling it's been getting...but it still looks connected.

allypally · 10-27-2008, 04:05 AM

The word I typed was s,h,i,f,t. Don't know why the censor saw that as a 4 letter word.
I think you will find, that if there is no signal comming into the software, TPMS Doctor, it will show as OFFLINE, so if that isn't the case, there must be some wifi going on.
All I can suggest is again to do a hard reset, then, while ensuring all other programs are closed, try learning 1 tyre to see if it is picked up. Others have suggested that after you learn a tyre, you should close the software, and then a few mins later, restart and learn the next tyre. Also, make sure your receiver is not being blocked by metal. If you can, place it outside of the car while learning. When you do get all tyres registerd, ensure they all have different HEX code. I have experienced a learning process, where I thought I had all tyres, but to find the codes were duplicated.
I am certainly not an expert in this matter, but have read some of the threads, and had similar frustrations to yourself. I suspect mine are not working properly, but I do not have the time, or patience to resolve the issues.
Good Luck.

Thanks for the help Ally...
After many complications with this (and HDRadio/BT, CF etc) I've gone and wiped out Vista in favour of XP (again!).
HDRadio is functioning perfectly, and I'm getting closer to putting this back in the car and learning the sensors (fingers crossed)...
Perhaps the TPMS works better in XP? Who knows...
I'll find out today...

Thanks again

2 questions :
As european kits generally use the 433.92 MHz freq, is it possible to use an 433.92 MHz Aurel RX module, rather than a hacked receiver, as long as it can handle the sensors output format ?

I was thinking (aooch my head.....), (correct me if I'm wrong)
Basically the pic reads the receiver output, recognize datas, format them and send them along the USB. In different kits (for a given frequency), what's supposed to change is the sensors format ? So the big question, is there a way to make the pic act like an oscilloscope ? I mean as long as the sensor format is unknow, the pic could work like a scope, sending raw datas to the computer . Once the format is figured out by the user, the decoding piece of code is send to the pic, which now knows how to deal with the sensors.

Kosti · 10-29-2008, 01:21 AM

How does one go about getting this kit chaps, I'm in Sydney Australia

I sent a PM to u Lok for some assistance

Hey guys, well it looks like we have some uphappy folk in the this thread so let me try to help those in need out. Wungun and others that have joined a bit late bes51659 has done us all as sevice and made a website that has all the 50+ pages worth of stuff condensed down to something that most of you should be able to understand. here is the link ( http://web.comhem.se/bengt-olof.swing/TPMS.htm ). Second I know I am probably going to regret this but if you think your reciever is busted I will offer to look at it as long as you pay for all the shipping costs (some beers wouldn't hurt either

). What I can do is take your reciever board clear the data and all the learned sensors, I will then use some of my test sensors to see if they will learn with your board. I know the sensors that I have work because I have tested them so at that point you will be able to narrow down the cause of the issues. Also I am not going to bend over backward so I will only ship using UPS and you will be responsible for shipping both to and from me. If you want some help send me a PM. Oh and the kits are getting there, I think we should have them ready by Nov5th only problem is that I am going to SEMA so I won't be here to ship them out. I will try to get someone else to ship them for me but I am only going to SEMA until the 6th so you won't have to wait too long either way.

Sounds like bending over backwards to me.

Thanks for all your hard work putting this together.

I, too, initially had problems, but this is a hobby so I know incorporating new tech is rarely plug-n-play. I kept experimenting till I got it to work and published my findings for others to know. That's what this forum is all about. I trust that the systems you'll have ready next week have all passed your quality control, so its up to me to get it to work with MY PC, MY car, and MY conditions. There are going to be those rare occasions where TPS doesn't work in a specific car with a specific PC installation (I just hope it doesn't happen to me).

Good luck to everyone on the prebuy list, I intend to make mine work - come Hell or high water!

WuNgUn · 10-30-2008, 04:36 PM

I'm convinced my receiver is busted...I was a little rough with it, and I lifted one of the traces off the board where the pin solders to it (by pushing down on the PCB)...I didn't notice this until yesterday.
But I did get a successful 'learn' off of it once...but only once.
On the plus side, all the sensor batteries were at full charge, so at least I don't have to pull the tires off any time soon...

I'll just wait my turn in line for the receiver...
Thanks for all the help everyone!
