M5.2 ECU Remapping

Raw Code. Real Results.

The Bosch M5.2 ECU – used in early BMWs like the E36 328i and Z3 – leaves plenty of untapped performance on the table. At Ozworx, we don’t just copy and paste generic maps. Every M5.2 remap is tailored with precision for your setup – whether you’re chasing more power, torque, or sharper throttle response.

We strip away factory limits, correct fuel and ignition tables, and give your engine a true performance edge – without compromising reliability. Cold start roughness, speed limiters, and soft fuel cuts? Gone. What you get is clean, consistent pull across the rev range, and a car that finally responds the way it should.

Features:

• Custom fuel & ignition mapping
• Rev limiter & speed limiter adjustments
• Cold start smoothing
• EWS delete & immobiliser defeat available
• Lambda/O2 delete for decat setups
• Pop/bang or overrun tuning (optional)

This isn’t off-the-shelf. It’s code rewritten for your build, your goals, and your drive.
