To use the module, you need to purchase a BitEdit USB protection key . The key can be purchased in our store. You can purchase an unlimited number of modules for one key.

Updates of descriptions for new software versions within the module are free.

Module activation is done within 1 hour on business days (usually 10-15 minutes). Activation may be delayed on weekends and holidays (up to 2 hours).

Only the serial number of the key and email are required to activate the module.

Important Information

1. No Refunds or Modifications for Digital Licenses

Activated modules or licenses cannot be returned or refunded.
If an incorrect key or device number is entered by the customer, the purchase is not eligible for return.
Licenses cannot be modified, transferred, or reissued for another device under any circumstances.

2. Irreversible Order Processing

After the order status changes to “Waiting for activation”, the data has already been sent to the developer.
From this point onward, the order cannot be canceled, edited, corrected, or refunded.

Octane Number FAQ

Important:

This function is available only on certain BMW engines and is NOT applicable to other vehicle brands.

The information below applies only to stock engines with factory ECU software and a standard exhaust system.

What This Parameter Actually Represents

This is NOT a direct measurement of fuel octane and is NOT a direct octane reading calculated by the ECU.

The value is an adaptation factor ranging from 0 to 1, where:

0 = no correction
1 = maximum correction

According to BMW’s internal definition:

Faktor adaptierte Kraftstoffqualität (0 = ROZ98 / 1.0 = ROZ91)

0 corresponds to 98 ROZ
1.0 corresponds to 91 ROZ

ROZ is the German equivalent of RON (Research Octane Number).

The device converts this multiplier into a more intuitive octane value for user convenience.

⚠️ The device does not measure anything itself.

It only displays the data provided by the engine control unit (ECU).

How the ECU Evaluates Fuel Quality

Each ECU has different calibration sensitivity:

Sensitivity to the adaptation factor
Sensitivity of the knock control system

Fuel quality is evaluated subjectively by the ECU, primarily based on:

Knock ignition timing corrections
Overall engine noise levels

BMW G-Series & LCI F-Series (B-Engines)

B38 / N63 / S63 / N74

These engines are highly sensitive to octane adaptation.

During warm-up and cruising, the displayed octane may frequently drop to 95 or lower.
This does NOT automatically indicate poor fuel quality.
Under load, the value should increase.

⚠️ If the value continues to decrease under load, this may indicate a problem.

B46 / B48 / B58

These engines have low sensitivity.

During cruising, octane will typically display maximum values even with mediocre fuel.
Under load, the value will decrease if fuel quality is truly poor.

S58

Octane correction is virtually inactive.

It will typically always show 98.
If it drops below 98, fuel quality is genuinely very poor.

BMW F-Series (Pre-LCI) with N/S Engines

Most pre-LCI F-series ECUs do not calculate octane adaptation.

Do not expect this parameter to function.

S55

Octane parameter not used by the system
Display not supported
However, display of the last 5 refueling quality events is supported

S63

Octane parameter not used
Display not supported
Refueling quality display not supported

BMW E-Series

Octane parameter not available. Display not supported.

Important Notes About Tuned Vehicles

With modified hardware or custom tuning, behavior may vary significantly. Always consult your tuner regarding expected operation.

Key principles:

If octane drops under load, it means fuel quality is worse than expected under those conditions.
This does NOT automatically mean the fuel itself is bad.

Examples:

If a tuner increases ignition timing and boost pressure, even good fuel may cause knock corrections, and the ECU may interpret it as poor fuel.
Thin-walled or poorly mounted exhaust systems may create parasitic noise, which the ECU may interpret as engine knock, causing negative correction.
Conversely, if knock sensitivity is reduced or octane correction is disabled in tuning, readings may appear ideal while actual engine safety is compromised.
