Chip tuning for BMW M5 4.4 (M compet.) 625 hp ECU
BMW M5 (2017 - F90) 4.4 (M compet.) 625 hp — premium petrol engine of the passenger segment of the BMW Group (Mini, Rolls-Royce, BMW Motorrad) group (Германия, 1916). Stage 1 chip tuning raises power from 625 to 700 hp (+75 hp, +12%) and torque from 750 to 850 Nm (+100 Nm). ECU — Bosch MG1CS201. Flashing method: OBD or Bench depending on the unit's protection. The ZF 8HPxx TCU is calibrated with a separate file — torque limiter and shift maps for Stage 1. In the CHIPOK database: 2 configurations · 2 ECU variants. The 2017 generation — mid-generation petrol ECUs (MEDC17/MEVD17/Simos PCR), OBD flash on production revisions.
BMW is a premium manufacturer from Munich, founded in 1916 as an aircraft-engine works. The factory calibration on BMW petrol engines is conservative, leaving headroom for Stage 1 without hardware changes.
The BMW community is renowned for active tuning and a large pool of available Stage files. Top BMW engines confidently reach Stage 2 with a downpipe + intake + intercooler. On older and mid-generation BMWs, Stage 1 is flashed over OBD without Bench. Bench reading is the standard procedure for top engines in modern models. Top BMW engines sit at the power ceiling, and the gain is significant. A well-known base once hardware is added (downpipe + intake + intercooler).
BMW's main gearbox is a modern multi-speed automatic. The gearbox comes in versions by torque class, so its tolerance depends on the engine. The TCU rarely needs recalibration up to Stage 1+, as the torque limiter usually copes with the Nm gain.
Frequently asked questions
How much does the power of the BMW M5 4.4 (M compet.) 625 hp increase after Stage 1?
After Stage 1 the power of the BMW M5 4.4 (M compet.) 625 hp rises from 625 to 700 hp, a gain of 75 hp (+12%). Torque rises from 750 to 850 Nm (+100 Nm).
How does Stage 1 differ from stock on the BMW M5?
Stage 1 on the BMW M5 4.4 (M compet.) 625 hp is a software ECU calibration with no hardware changes. The key maps (boost/ignition/lambda/torque) are adjusted while factory tolerances are preserved. The gain is +75 hp with no hardware changes.
What does Stage 1 give on the top-spec BMW M5 4.4 (M compet.) 625 hp?
Stage 1 for the BMW M5 4.4 (M compet.) 625 hp unlocks the potential built in by the factory but artificially capped to meet mass-market targets. A base of 750-800 hp is achievable once hardware is added.
How does Stage 2 differ from Stage 1 on the BMW M5 4.4 (M compet.) 625 hp?
Stage 2 on the BMW M5 4.4 (M compet.) 625 hp means software + hardware (exhaust, intake, intercooler). The gain depends on the specific hardware combination.
What control unit does the BMW M5 4.4 (M compet.) 625 hp run?
The control unit of the BMW M5 4.4 (M compet.) 625 hp is the Bosch MG1CS201. Before flashing, the engineer identifies the exact revision and selects the write method.
Does the ZF 8HPxx transmission need calibration after Stage 1 on the BMW M5?
Remapping the ZF 8HPxx gearbox is essential to fully unlock Stage 1 on the BMW M5 4.4 (M compet.) 625 hp. Without a TCU update the factory torque cap will choke the torque gain and shifts will become noticeably softer.
Does Stage 1 void the warranty on the BMW M5?
Stage 1 on the BMW M5 voids the factory warranty on the engine and transmission — this is standard for all manufacturers. CHIPOK provides its own warranty on the quality of the remap.
How quickly is chip tuning of the BMW M5 4.4 (M compet.) 625 hp done?
The full remap cycle for the BMW M5 — from reading to writing the final file — takes 30-90 minutes depending on the ECU access method. The file is prepared at CHIPOK in 5-30 minutes.
Can you return to stock after Stage 1 on the BMW M5?
The original BMW M5 ECU is always saved before flashing. Rolling back to the factory firmware is done with the same programmer in 25-30 minutes.
How much does Stage 1 cost for the BMW M5 4.4 (M compet.) 625 hp?
The cost of Stage 1 for the BMW M5 4.4 (M compet.) 625 hp is calculated in the calculator on this page — you select the options (DPF off, EGR off, AdBlue off, DTC off, etc.) and the price is capped by the package Max Price. Payment is by credits (1 cr = 1 €), with no subscriptions.
