Starting a remapping business almost always begins with the same question: which tool should I buy? Behind it hides a structural choice, the operating mode: slave or master.
Slave and master, the real difference
A master tool reads and writes files in the clear. You see the data, you can modify it yourself or send it to whoever you want. A slave tool reads the same ECUs but encrypts the file: only the file service it is tied to can decrypt and modify it. In exchange it costs significantly less to buy and is far more forgiving in daily use.
Slave: the right starting point for most workshops
If your trade is the workshop, taking vehicles in, diagnosing, flashing, testing, slave is almost always the right first choice. The investment is reasonable, protocols are kept up to date by the manufacturer, and responsibility for the calibration stays with the file supplier. You invoice the job, we answer for the map.
It is also the safest way to build skill: you learn reads, protocols and the traps of each platform without carrying the risk of a badly built file alone.
Master: for whom, and when
Master makes sense when file modification becomes your core business: serious volume, specialisation on certain platforms, the ambition to develop your own calibrations. It also means owning everything that comes with it: proper training, serious testing means, and direct responsibility for every modified byte. Many workshops move to master after two or three years on slave, once volume and experience are there.
Both work with our file service
We take slave reads from the common tools as well as master files. The portal identifies the format on upload and the file comes back ready to flash, checksum corrected. If you are still hesitating, write to us with the brands you see most in your workshop: we will tell you frankly what we would choose in your position.
