Bosch diesel ECU on a Tricore core (TC1796/TC1797) — the mainstream TDI/CRDi platform of 2008-2018 — found on Hyundai and Kia (26 modifications). On the Bosch EDC17C08, CHIPOK performs Stage 1/2 — power tuning, software removal of the diesel particulate filter, EGR, AdBlue, catalyst control, disabling the intake flaps, Hard Cut Limit, speed limit removal, DTC removal, return to stock and Start/Stop Off. Flashing is done via KESS3 / Autotuner / CMD Flash / FGTech Galletto.
The Bosch EDC17C08 unit is found on 26 different engines. Main brands: Hyundai (13), Kia (13).
The Bosch EDC17C08 ECU supports: STAGE 1, LAMBDA OFF, ECO TUNING, START STOP OFF, HARD CUT LIMIT, EXT FLAPS OFF, ADBLUE OFF, STAGE 2, EOLYS/ADDITIVE OFF, CHECK STOCK OR NOT. Checksums are recalculated on the engineer's side in WinOLS5.
The Bosch EDC17C08 is supported by: KESS3 (OBD bootloader), Autotuner, MPPS V21, KTAG (Bench for Tricore), Trasdata, CMD Flash. On production models OBD reading is usually enough; on locked variants — Bench (BDM/JTAG).
Stage 1 on the diesel Bosch EDC17C08 reprograms rail pressure target, SOI/EOI timing, boost target, smoke limiter and torque limiter. The torque gain is noticeable; the HP gain depends on the specific engine.
The original bin/hex/ori is accepted after reading via KESS3 / KTAG / Autotuner / MagicMotorSport. Checksums are recalculated on the engineer's side.
OBD flashing of the Bosch EDC17C08 — 25-30 minutes, Bench (if needed) — about an hour. The file processing itself takes 5-30 minutes after receipt.
The cost of a Bosch EDC17C08 file is built in the calculator: you pick the operations you need (Stage 1, emissions removals, service operations) and the price is calculated with the package discount applied.
