PERON Stage 2 ECU Tune | xHP Stage 3 TCU Tune | BMW M140i / 440i B58
PERON Tuning Stage 2 ECU & TCU Calibration for BMW B58 (M140i / 440i)
At PERON Automotive, our Stage 2 ECU and TCU calibration package for the B58-powered M140i and 440i is the culmination of extensive in-house development and collaboration with global partners. The already-impressive B58 engine gains significantly in performance while retaining the smooth, OEM-like drivability that makes these models so rewarding.
Performance and Drivability
Our Stage 2 calibration raises power toĀ 435ā450 hp and torque to 460 lb-ftā475 lb-ft on 99 RON fuel, delivering a more potent mid-range pull and enhanced top-end performance. The map has been engineered for seamless torque delivery and precise throttle control, making it equally at home on your daily commute or a spirited weekend blast.
ZF 8-Speed Gearbox Calibration via xHP
To complement the ECU upgrade, we provide a TCU tune using xHP software, specifically tailored for the ZF 8-speed automatic transmission:
- Faster, more responsive shiftsĀ Ā
- Optimised torque-converter lock-upĀ Ā
- Revised shift logic in Sport and Manual modesĀ Ā
- Raised torque limits to suit the increased outputĀ Ā
The result is a gearbox that feels sharper, more intuitive and perfectly in sync with your engineās newfound vigour.
Fuel Requirements
While optimised forĀ 99 RON, the Stage 2 tune remains fully compatible with 97ā98 RON, delivering performance gains without compromising fuel economy or day-to-day usability.
Recommended Hardware
- OEM BMW B58 spark plugs (if not recently replaced)Ā Ā
- Performance panel air filter and upgraded intake hoseĀ Ā
- Performance downpipe with high-flow catalystĀ Ā
Tuning Highlights

- Increased stationary rev limiter for a more evocative exhaust noteĀ Ā
- Thorough throttle-map development for a smooth, linear responseĀ Ā
TCU Calibration (xHP)
- Recalibrated shift points and strategiesĀ Ā
- Improved gear hold in Sport and Manual modesĀ Ā
- Increased shift speed and reduced lagĀ Ā
