About this calibration file

The Stage 3 calibration for the 1992 Audi S4 2.2L Petrol targets a hardware-upgraded setup — hybrid or larger turbocharger, upgraded injectors, high-flow fuelling and in most cases a full exhaust. Maps are redrawn for the new airflow envelope with re-scaled MAF/MAP, torque limiters, smoke limiters and boost PID re-tuned.

This file matches a Bosch ECU with hardware number 0261200465. Verify both identifiers in your flashing tool before writing — an ID mismatch is the most common cause of a bricked ECU. If you are unsure, upload a read of your original file via the file-request wizard and our engineers will confirm compatibility before you flash.

The file is delivered as a ready-to-flash BIN (and ORI backup where applicable) compatible with all major tools — KESS V2/V3, KTAG, AutoTuner, CMDFlash, Dimsport New Genius, MPPS, Flex, BFlash, PCMFlash, MMFlash — via OBD, bench or boot-mode as supported by your ECU family. Checksums are pre-computed and verified; no additional checksum tool is required. All files include a free revision if post-flash logs reveal a fuelling, boost or EGT issue.

Frequently asked questions

The file is written for the exact ECU hardware 0261200465 (Bosch) listed in the specifications. Read your ECU with any supported tool (KESS, KTAG, AutoTuner, CMD, etc.) and compare the hardware + software numbers against the ones on this page. If they match exactly, the file is a direct fit. If you're not 100% sure, upload your original read via the file-request wizard and our engineers will confirm within minutes — no cost, no obligation.

This stage targets a built setup — hybrid/larger turbo, upgraded injectors, high-flow fuelling, and in some cases upgraded transmission/clutch. Running the file on stock hardware is not supported and can cause detonation, EGT spikes or overboost fuel cuts.

Re-flashing the ECU leaves a flag that a franchised Audi dealer can detect with their diagnostic tool. Most markets treat this as a basis to deny powertrain warranty claims that the modification could have caused. Emissions-sensitive components (DPF, EGR, SCR) remain fully functional with this calibration — we do not remove, disable or alter any emissions hardware.

The power and torque numbers on this page are healthy-engine crank figures. On a well-maintained 1992 Audi S4 running a known-good fuel brand, you should see a clearly perceptible increase in mid-range pull — typically from 1,800 to 4,000 rpm on diesel, 2,500 to 6,000 rpm on petrol — along with a shorter 80-to-120 km/h in-gear time. Thermal performance and fuel consumption depend on how you drive post-tune.

Instant. Immediately after payment clears (typically < 30 seconds on Stripe / PayPal), the download link appears in your account dashboard and is also emailed to you. The link is a signed, expiring URL — download it within 24 hours; if it expires, just re-generate from the dashboard at any time.

Pre-corrected. Every tuning file we sell is processed through CHKSuite (our in-house checksum engine) before it reaches your download link. You can flash it directly with KESS, KTAG, AutoTuner, CMD, Dimsport or any other supported tool — no extra checksum step required. A zero-CRC write to a modern Bosch/Siemens/Delphi ECU bricks the unit, so this is non-negotiable.

Contact us on WhatsApp or through the dashboard support thread. Free revisions are included for the same stage on the same ECU — send us a live log (via VCDS, INPA, EcuConnect, OBDeleven or similar) and we'll adjust timing, boost, rail pressure or smoke limits and re-issue the file. A failed flash itself (write aborted, bricked ECU) is recoverable with our Original file and a bench tool.

This product contains a calibrated Stage3 tuning file for Audi S4 2.2 Turbo 1992 Turbo-Benzin 169.2KW with Bosch 0261200465 and software ID 4A0907551A (Bosch software number 356703 ( 1037356703 )). The base stock vehicle for this calibration has a factory output of around 169.2 kW (~230 HP). This high-stage file targets heavily modified setups (bigger turbo, injectors etc.) and should be used by experienced tuners only.

All ECU tuning files from TUNING-DATABASE are prepared for professional use. They are useful whenever you search by ECU ID, hardware or software number such as 0261200465, 4A0907551A, 356703 (1037 + SW code). Use this file for diagnostics, cloning, recovery or as a base for custom remapping.
