Jac tune files, map packs & software solutions

18 models · 42 engine/ECU combinations · 20 ECU types · files for Autotuner, KESS3, Flex, Dimsport DFOX / New Genius, PCMflash, MMCFlash, BitBox and more

Every Jac below can be read and written with a current flashing tool — Autotuner, KESS3, Flex, Dimsport DFOX / New Genius, PCMflash, MMCFlash, BitBox and more — and we build custom files for all of them from your own read: Stage 1 and 2 calibrations, towing and economy files, DPF/EGR/AdBlue solutions, DTC work, speed and rpm limiters, TCU shift and torque tuning, plus WinOLS map packs and DAMOS files where we hold our own definitions. WhatsApp Josh directly on 0466 659 997 — you deal with the person building the file — or upload at tacfiles.com for an automated return.

Vehicle, ECU and read-method data compiled from the published compatibility lists of the flashing tools we work with; files are returned in the format your tool writes — Autotuner, KESS3, Flex, Dimsport DFOX / New Genius, PCMflash, bFlash, BitBox and more (see the tools page). Read methods are as published by the tool lists. Listing here means the ECU can be read and written with a current tool and we can build a file for it — WhatsApp us to confirm your exact software version. All tuning files are intended for off-road, motorsport, agricultural or commercial use only.
