Found two more diagnostic scanners, one is the cheapest option I have seen.
CarMD is a basic scanner with limited reporting and diagnostic for the unaware end-users, costs only $99. Very simple to use and understand.
Autotap is a more comprehensive solution providing a detailed diagnostic and live data on the sensors and running vehicle. Costs $200 for the Hardware & software + you can buy more enhanced parameters.
Remember, both are diagnostic scanners only and cannot be used for tweaking the ECU. Please view their Demo videos for better understanding.
Ehhh!!! anyone in/ going to US and will be back soon,
