On October 6, 2026, SMS-Soft shipped build 7.2026.123.5945 of ChipTuningPRO 7 — and this is not the usual round of minor fixes. The update adds full calibration editing for a handful of high-volume engine control units, headlined by BMW's Bosch MEVD17.2.9, General Motors' ACDelco E82, and VW Group's Bosch MED17.5, alongside new map support for Hyundai/Kia and the freshly launched Lada Iskra. For a tuner, that means a stack of common petrol engines just moved from "read-only" to "fully editable."
What's in Build 7.2026.123.5945
SMS-Soft structures ChipTuningPRO releases in two parts: interface and editor improvements, plus new ECU and firmware support. Build 7.2026.123.5945 delivers both. On the editor side, the update fixes a data-integrity bug where changes made in 3D surface and table edit mode were not saved when viewing graphs in isoline mode — the kind of silent failure that can quietly corrupt a tune. It also corrects a 3D map difference calculation that showed incorrect visual variance between identical axes, resolves a UI color-settings display issue, and improves the recent-files list with a custom item limit and correct chronological sorting by open date.
The more consequential half of the release is the ECU coverage. Five platforms gain new or expanded calibration support, and several of them sit at the heart of the everyday European, American and Asian petrol fleet.
The New ECU Coverage, Decoded
BMW Bosch MEVD17.2.9 — Full Calibration Editing
MEVD17.2.9 is the engine management behind BMW's N20/N26 family, the 2.0-litre turbocharged four that powers a long run of 3 Series, 5 Series, X1 and X3 models, plus the 2.0-litre Toyota Supra and a broad slice of MINI product. The new build adds full calibration editing for software ID 99U9EH0B, which means tuners can now edit the calibration maps directly instead of viewing them or working through partial patches. For a platform this common, that shift removes a recurring bottleneck in an otherwise routine remap job.
VW Group Bosch MED17.5 — Extended Calibration Maps
MED17.5 runs a huge portion of the Volkswagen Group's turbocharged petrol lineup, including 1.4, 1.8 and 2.0 TSI/TFSI applications across Volkswagen, Audi, SEAT and Skoda. The update extends the calibration maps for software versions CGYA-N08K3 and CCTA-NJ9E16, giving tuners more editable parameters on one of the most frequently tuned ECU families in the aftermarket. When a VW or Audi owner asks for a stage tune, MED17.5 is often exactly the unit under the bonnet.
GM ACDelco E82 — New Software Support
GM's E82 controller manages the automaker's modern turbocharged petrol engines, including the 2.0T LTG family found in the Chevrolet Camaro, Buick Regal, Cadillac ATS and Malibu. New support for ACDelco software version 12716345 brings those vehicles into the editable fold, extending ChipTuningPRO's reach across the North American turbo segment that tuners have long serviced with a patchwork of single-brand tools.
Hyundai/Kia KEFICO CPEGD3.26.1 — Map Additions
KEFICO is the Korean supplier behind much of Hyundai and Kia's GDI engine management. The update adds corrections and map additions for the ATRNADA3 software variants of the CPEGD3.26.1 module, deepening coverage on a brand pair that continues to grow its share of both the new and used car markets worldwide.
M74.9 Lada Iskra — A Brand-New Platform
Rounding out the list is a genuinely new vehicle: the Lada Iskra, the latest compact from AvtoVAZ. ChipTuningPRO now supports the M74.9 firmware used in the Iskra's 21129 CVT application and ships a new engineering firmware based on the same M74.9 core for the OnLineTuner kit. It is early support for a platform that will matter more as Iskra volumes build in the regions where it is sold.
Why the 3D Map Editor Fixes Matter More Than They Sound
A map editor that fails to save is worse than no editor at all, because it lets a tuner believe a change was written when it was not. The isoline-mode save bug fixed in this release is exactly that class of defect, and it is the kind of issue that produces "the car ran fine for a day, then the map reverted" support tickets. Quiet stability work like this is what separates a tool you trust with a customer's ECU from one you babysit.
What This Means for Your Workflow
Every newly supported ECU is a job you can now finish in-house instead of turning away. BMW N20/N26 tuning, VW Group MED17.5 stage tunes, and GM 2.0T work are high-volume, high-margin services, and each one previously required a separate tool, a bench setup, or an outsourced file. Consolidating them into a single calibration platform shrinks both your tool budget and your turnaround time.
To make the most of the new coverage you will want a toolchain that can actually reach these controllers. Start with a dedicated chip tuning interface and a set of ECU bench adapters that cover the MEVD17 and E82 families, then keep the software current through your software update service so the map database does not age out. For the workshop that also does fault-finding before it tunes, a solid car diagnostic tool closes the loop between diagnosis and calibration.
A Note on Legal and Safe Use
Calibration editing changes how an engine behaves, which can affect emissions, warranty and road legality. The new coverage in build 7.2026.123.5945 is a professional capability, not a licence to defeat emissions controls. Use it for authorized repairs, motorsport and off-road applications, and always verify a map on a dynamometer before releasing a vehicle to a customer. A clean, reproducible tune protects your shop as much as it protects the car.
