What going to kill the engine ? If car is snatched how user goona activate the timer for engine kill?

engine is killed by MOSFET based digital logic circuit, if the car is snatched the timer is activated by circuit itself.

salam bro can u tell me kindly what will be the cost of full digital speedo meter for suzuki baleno?whch can show correct accurate reading especially cng nd fuel reading nd fuel average per kilometer kindly tell me asap nd also where i can get it fitted from in rawalpindi islamabad because its not easy to install it nd i dont hav any knwlg i live in rawalpindi....baleno 2004 1300cc...w8ng for ur reply

i have not made any speedometer type circuit,:S

How MOSFET goona kill engine by shutting off ignition or fuel? How the security system would know that the guy drive the car isnt own any chipped key or something?

[zaeem9236]

yes, by cutting fuel pump, ECU, and ignition.
the circuit is connected with all doors of cars.
car is in anti-snatch mode + the door open=timer activated.

nope, primary circuit is connected with fuel pump and ecu, if the car is in lock mode and some one bypass one of these thing,
the second circuit gets activated which will burn ignition coil fuse.
after all i am interested to kill engine by ECU, which is too difficult but hope is everything(H)

good work dear
you can cut signal from crank shaft position sensor connect to ECU, when you disconnect this single engine could not start.

yes, thanks for suggestion

I think best way to anti theft technology is to modify ecu .... for example when you insert the key , key should have encryption on it ... and ec should have decryption ... car should not start untill encrypted car key is entered to switch and let the switch send the signal to ecu .... encrypted key can not be opened anyway unless someone remove ecu....

What if the theif come with a ecu immobilizer equipped are stolen the same way

I was thinking about this issue right now ...

A master control (small processor) having a serial no and ecu having same serial can do the trick if ecu serial codes doesn't match with master control ki all door get locked and alarm triggers (H)

If thief cut master control and insert genuine witing to ecu... then?

Master control would have control on fuel pump master control wirring cut =non working fuel pump now theif won't waste his time finding the source of problem

I also use some technique to protect my car .... a very simple but confusing technique ..hope u r familiar this ine with fuel supply related... i dont want to mentiin there for protection

@saboor73 , @searchingeyez thanks both of u for your suggestions,
i am doing work on my next project obd2 using micro-controller,
is there any way to disable engine by obd2?

U can stop injectors power supply....

I think main object for fool proof theft and stealing is to protect ecu swapping .....

There is a need of creating a system nd algo that let the ecu to authenticate the car on which its belongs to and thats the issue how to authenticate the car withiut the wires ....

bro whats the price for honda city idsi 2005?

[humayun.chughtai.7]

Any update regarding your project ...

[umairalvi815955]

price for mehran??

@moreumair,
@humayun.chughtai.7
sorry for late reply, i am working on new RFID based systems for car protection.
