We hope by now you know that there are loads of features that make COAD®

stand out but couple main ones are as following

COAD® Complete OBD & ECU Auto Diagnostics is a 2-in-1 package:

Most competitors either provide:

  • OBD software: Performs car diagnostics, scanning, reading, fault analysis, etc.
  • ECU Remapping software: Changes cars actual operating procedure. For example more/less fuel injection, 
    editing maps, etc...

Whereas COAD® applications do both.

Personalised database supporting Generic and Car specific OEM fault codes/parameters:
Most competitors will only provide software that deals with generic universal OBD codes/parameters (applicable to all cars). Meaning most of car-brand-specific factors won't be read. Usually limiting the software at 50% of it's capabilities.

Where as COAD® has it's own database which comprise of generic and car-brand-specific codes/parameters. Meaning you'll have equal control of the car's OBD/ECU as dealership

Professional support, free guides and repair manuals:
COAD® contains manuals that include thousands of pages on fault codes, patches, PCB layouts, pictures, schematics, repair instructions, etc...

The Manuals are all layed out in a step-by-step, structured order and easy to understand, even for an average home person. However it does have comprehensive sections for advanced mechanics/service repair shops.

For example, each chapter shows trouble codes, their probable causes, their locations, and their solutions.

In addition, it also lists all the car models throughout the world to whom those codes, faults and solutions apply. So it doesn't matter what car you own or dealing with, because it's included with sections of dedicated material on it.

Meaning you'll save time and frustration by quickly pin-pointing the problem and how to fix it using the most cost-effective way.
