Hardware
  • Sport / decat downpipe (or DPF removal where legally permitted off-road)
  • High-flow air intake (recommended)
  • Optional: catback exhaust for lower backpressure
Software / Calibration
  • DPF / EGR / AdBlue switched off in software (where lawful)
  • Boost & rail pressure raised to match new airflow
  • Smoke limiter relaxed in line with hardware
  • Lambda + EGT safeties retuned

Stage 2 keeps the factory turbo and internals. Final figures vary slightly with the exact hardware fitted.

Engine performance matrix

Power, torque and fuel-economy figures for every tuning stage on this engine, sourced from the tuning-database Gains API. Values are healthy-engine crank numbers; real on-road gains vary with fuel, altitude and mechanical condition.

Fuel economy gain (vs. factory map, same driving profile): combined cycle −8% , full-load cruise −12%. Diesel calibrations typically net bigger combined-cycle savings thanks to shorter duty-cycle on low-load driving.

About this calibration file

The Stage 2 calibration for the 2002 BMW E90 E91 325d Turbo Diesel is written for vehicles with supporting bolt-ons: a higher-flow downpipe or sports catalyst, upgraded intercooler and upgraded intake are recommended. Boost targets, fuel-rail pressure, injector duration and VGT positioning are pushed further than a Stage 1 map while keeping exhaust-gas temperatures inside safe bands.

This file matches a Bosch ECU. 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.

Projected output on a healthy, stock-hardware example of this engine: 232 HP and 499 Nm at the crank — a gain of +39 HP (20%) and +89 Nm over the factory 193 HP / 410 Nm baseline. These numbers are sourced from our Vehicle Performance Database, which aggregates dyno results across this engine family. Real-world gains depend on fuel grade, ambient temperature, mechanical condition and intake/exhaust state.

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 (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.

Stage 2 benefits from a higher-flow downpipe or sports catalyst, an upgraded intercooler on forced-induction engines, and in some cases a cooler intake. The map will run on stock hardware but will not reach the quoted figures without the supporting bolt-ons.

Re-flashing the ECU leaves a flag that a franchised BMW 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 2002 BMW E90 E91 325d 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 Stage2 tuning file for BMW E90-E91 325D 2002 Turbodiesel 144.9KW with Bosch O and software ID 11JAD4 (Bosch software number 390114 ( 1037390114 )). The base stock vehicle for this calibration has a factory output of around 144.9 kW (~197 HP). Stage 2 is intended for cars with supporting modifications (exhaust, intake, intercooler) and delivers a stronger performance gain.

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 O, 11JAD4, 390114 (1037 + SW code). Use this file for diagnostics, cloning, recovery or as a base for custom remapping.
