Calibrated from your logs.
No dyno appointment. You flash a base calibration, log the car and send it back, then we read the data and revise until it is clean.

Submit your build
Chassis, engine, full mod list and target fuel. This defines a safe calibration starting point before any file is touched.

A conservative calibration matched to your hardware and fuel, flashed with your own software at home.

Log and send back
Full-throttle pulls and part-throttle data captured on our channel list, then sent over for review.

Review and revise
We read the logs, adjust the calibration and repeat until the car is running clean and on target.

Technical reading for the N20, and the pages around it.
- Tune pathBMW B58 Stage 1 TuneB58 Stage 1 is a custom ECU calibration on the factory turbo and factory exhaust. What it changes, what your car needs first, what to log, and what it costs.
- Tune pathBMW B58 Stage 2 Tune (Downpipe)B58 Stage 2 is the calibration for a downpiped car: less backpressure, different wastegate behaviour, and a charge-air load the stock intercooler was not sized for.
- Tune pathBMW B58 E30 TuneA B58 E30 tune is a calibration for a fixed 30% ethanol blend. What E30 buys in knock resistance, what it costs in fuel flow, and how to mix it repeatably.
- Tune pathBMW B58 E85 TuneA full-E85 B58 calibration asks 30-40% more fuel mass than pump gas. What the fuel system must support first, and why E85 is a hardware decision before a tune.
- Tune pathBMW N55 Stage 1 TuneN55 Stage 1 is a custom ECU calibration on the stock turbo and stock exhaust. What it changes, why the E-series and F-series cars differ, and what to log.
- Tune pathBMW N55 Stage 2 Tune (Downpipe)N55 Stage 2 is the downpiped calibration: lower backpressure, re-scaled wastegate control, and an intercooler that becomes the real limit on repeat pulls.
