An ECU/TCU remapping tool (Alientech KESS3, Autotuner, bFlash, Magicmotorsport FLEX) is not enough on its own: each operation in OBD, Bench, or Boot mode requires the right cable, the right adapter, and a stable power supply to avoid any interruptions during ECU writing. This category includes everything you need to make these tools work properly, workshop after workshop.

Accessories that protect your calculator
Engine remapping requires a stable electrical voltage throughout the ECU's read and write process. A drop in voltage during the operation can permanently damage the ECU or TCU (permanent blocking of the control unit). A suitable battery charger, kept connected throughout the intervention, remains the best protection against this risk.
OBD, Bench, and Boot cables, on the other hand, determine the compatibility of your device with the various ECUs on the market (Bosch, Delphi, Marelli, Siemens, Continental...). A poor connection or an unsuitable cable can distort the reading or interrupt the writing in progress of your engine remapping tool.
RS-Tronic offers a selection of compatible accessories with leading brands (Alientech, Autotuner, bFlash, Magic Motorsport) to fully equip your workshop.
