Hi,

Can someone tell me how do i analyze the OBD information recieved from ECU?
I am using CAN interface and i need to analyse the different data (DTC, Freeze frame ..) and display the recieved information using display interface.

So how do i analyse different types of data recieved from ECU ?

There's nothing that'll simulate the entire flash procedure available at any reasonable price. Many ECUs have a boot-block so you won't kill the ECU even if you have a bad reflash. Ford, Chrysler, newer GM's you're ok. Really it's the older VPW GM's that you have to worry most about killing.
