Other factors include the number of Chinese/EU cloned tools on the market, which try to emulate the real equivalent, however these will always let you down at some point. There are many different tool manufactures on the market now, all competing by price and range of protocols they support. Some franchise operators can be very unclear about this, it is becoming more common to see unhappy clients looking to use another tuning file supplier only to find they didn’t know that ‘their?’ equipment is slave and the limitations of options moving forward as the 2-3 k they invested has been little more than a rental for a year, where for truth and just few pounds/euros/dollars more all could have been so different. Main reason businesses are realising that if they invest a little more money for a master tool, then they will have more options in terms of the chip tool, tuning file suppliers and at the end of the day, the result will be a free and clear asset to your business. The traditional master / slave tooling business model used by current car tuning companies is slowly being phased out for a number of reasons. Chip tuning / ECU remapping through the last year or two has started to take a turn.
