Reading data

[PugLover]

Hello everybody,

You may find this question a bit silly but I am curious about answers and where it goes.

I have a Peugeot 2003 model 307 SW. I want to build some projects on 307's electronics. I don't know if anybody else has already tried this but I just want to read some data from the bsi of the car, i.e. current speed, current rpm. I don't know if I am even allowed to do it. Could you please shed some light to me?

Thank you.

Can you not just look at the instruments Explain

Here is an example.
As you know, there is a property in some cars that after certain speed, doors are locked. I don't have this property in my car. If somehow can read the current speed from BSI, I can easily implement an application to do so. This is just an example and I have another ideas that can be implemented if I can read some data from BSI like speed, RPM and so on.

On my 407 there is a button on my dash that changes the locking procedure , and yes you can read live data through the parameters on different ecu`s in the car giving you all the info you need.

Could you please give me more info in detail? What kind of interfaces, tools or circuits I need? Where should I start?

I googled it and encountered with this sentence. Is it important for me because I have 307 SW. Can you comment on it?

It compatible with most Peugeot cars from 1995,but it can not work good with Peugeot 307.

It works with 2002 ,2003 , 2004 , 2005 307`s because i have used it on them, somebody selling something they haven`t used i suspect, no worries.

I appreciate your helps betty.

As far as I understood, I always need to have a laptop in the car in order to read data from Lexia 3. I am aiming to read data via a microcontroller. Do you think my idea is way impractical?
