Comparison: Why Choose Toad Pro And Not Any Other OBD2 Software?

Even though there are several OBD software and dongles on the market, a few are better than the Toad Pro software. Some of the software that competes with Toad Pro are FORscan and Auto Doctor.

FORscan is a popular OBD software with outstanding features. However, this scan tool is not better than the Toad Pro for several reasons. First of all, this tool is compatible with a handful of car makes, including Ford, Lincoln, Mazda, and Mercury vehicles.

Secondly, FORscan uses only a lite version of the tool on mobile phones. Therefore, if you desire to enjoy all the features of this OBD2 software, you will need to use a tablet or windows-based laptop. Additionally, despite this software allowing some free readings, most functions have to be purchased.

Another popular software that you may have come across is Auto Doctor. This OBD2 software is popular because it is free to download. However, the manufacturer uses this hack as the software is not totally free. You will have to purchase the License, or most of the information will stay locked.

Aside from requiring a License, Auto Doctor will also need an ELM327-based adapter to function, which of course, you guessed right; you will have to buy it.

Unlike FORscan and Auto Doctor, Toad Pro doesn’t come with such challenges, and that’s why many people prefer this OBD/OBD2 software over its competitors.

What features do Total car diagnostics offer that the FORscan and Auto Doctor software doesn’t provide?

As stated above, the Toad Pro scan tool has a lot of benefits than the FORscan and Auto Doctor OBD software. Aside from that, this tool comes with more features than the FORscan. Some of these features include supporting Controller Area Network (CAN). Other features include IMMO keys, DTC lookup, ECU programming, Full Systems Diagnostics, Key programming, and reset/regeneration/calibration/relearn systems.
