Flash ECU by OBD port (procedures)

In this post i talk about flash the ecu by obd port.
I recommend some procedures to everything runs good.

If you do not have this i recommend you to buy and so before you can flash your ecu:

*battery charger
*Extension Power Supply
*recovery tool (optional, but important)



Verify the car
Turn Off all ancillaries if you know of any large power drains, turn it off, you can make it only need pull the fuse in the fusebox car .
I recommend discard the plug or withdraw the fan fuse, because If the car is still hot the fan can turn on.
Verify the car battery, see if it is good (12,5v) and connect the battery charger.
In my case, i always make this (i recommend it).

Verify your laptop
Verify the laptop battery, see if it is good and connect the charger to extension power supply (i recommend it).
Close all other programs on your laptop.
Disable all hibernate, standby and screensaver options. Turn off the antivirus software.
Only open the software to flash your ecu.

Verify the file
If you downloaded the file from a site or someone that you do not know handed him, please confirm with other chiptunner if the map is good or not (many files in internet are garbage, and can damage your engine) and make sure that the hardware and software are the same.
Ensure the file you wish to flash has definitely had the checksum corrected or your tool can correct it for you (make this always, I use two program the last is to confirm if the first did a good job).

Recovery
I recommend to have a tool to make recovery. If something goes wrong you can repair it

You are ready
After this you can flash your ecu.
Has only attention to any disconnect in tool when you flash the ecu.
