What the car needs
Required modifications: Stage 2, Petrol.
Hardware
- Sport / decat downpipe (or sports-cat)
- High-flow air intake
- Optional: front-mount intercooler upgrade for sustained boost
Software / calibration
- Cat-warm-up & secondary lambda re-mapped for decat hardware
- Boost target raised in line with cooling capacity
- Knock / ignition advance re-trimmed
- Idle and load-transition tables refined
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.

About this calibration file
The Stage 2 calibration for the 1999 BMW E36 318i Petrol 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 with hardware number 0261201159 and software version 377861. 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: 164 HP and 228 Nm at the crank — a gain of +23 HP (16%) and +32 Nm over the factory 141 HP / 196 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.
