Flash programmers are aimed at enthusiasts wanting that little bit extra from their cars. Like most electronics, there are many factors to consider as below.

Some vehicles may even struggle to use all of the features that a flash programmer has. Many include hundreds of features to perform more alterations to your vehicle from speedometer modifications to gearbox adjustments.
You may also notice that a brand will separate a gas flash programmer to a diesel alternative. This is a common mistake made, so be sure to check both the car manufacturer and the fuel type before buying.
