MD-Lambda-View: Carburetor adjustment with a lambda sensor made easy!

MD-Lambda-View is a data logger for lambda value, engine speed, and throttle position (or carburetor slide position). MD-Lambda-View works with a Bosch LSU 4.9 wideband lambda sensor to determine the current lambda value. Engine speed is measured via terminal 1 on the ignition coil, while throttle position (or carburetor slide position) is measured using a simple potentiometer, the existing throttle position sensor (if 5V), or the MD-Lambda-View cable-operated sensor. The logged data is stored in internal memory and can be renamed, saved separately, or downloaded via the web interface for analysis with the MD-Lambda-View evaluation software.

WIRELESS

Connection to mobile phone, tablet or PC via integrated WIFI hotspot

EASY INSTALLATION

The connection to the vehicle is uncomplicated and quickly done for the experienced mechanic.

ALWAYS READY

MD-Lambda-View is operated via the on-board electrical system of your vehicle.

SMALL DIMENSIONS

MD-Lambda-View is 70mmx36mmx17mm (without wiring harness). MD-Lambda-View always finds a place.

SIMPLE USAGE

The visualization, operation, and settings via a web interface are intuitive and easy to use. No app is required!

HIGH COMPATIBILITY

MD-Lambda-View can be individually integrated into your vehicle environment using additional adapters.

With MD-Lambda-View, you have a complete overview of all important engine parameters at all times – precise, in real time, and directly while driving. The integrated Wi-Fi web server clearly displays all measured values on Wi-Fi-enabled devices. You can easily access the data via smartphone, tablet, or laptop – no app required, directly in your browser.

MD-LAMBDA-VIEW DATA EVALUATION

3D Analysis

With the MD-Lambda-View data analysis software, you can visualize and analyze your saved logging data in detail. The web application creates a clear 3D surface diagram from lambda values, engine speed, and throttle position, showing you how the mixture behavior changes in different load and engine speed ranges. Various display and filter settings help you optimally adapt the visualization to your needs, ideal for EFI tuning or analyzing engine performance and lambda values.

2D Analysis

With 2D analysis, you can visualize your logging data if you only log the lambda value and the throttle valve or carburetor slide position, as is common with a carburetor.

2D data analysis

Both data analysis tools are freely available web applications that work in any modern browser. No installation is required; simply open the application, load the CSV logging data, and immediately analyze the most important engine parameters in 3D or 2D diagrams.

MD-LAMBDA-VIEW CABLE PULL SENSOR

smart cable pull sensor for carburetor tuning

Reliably determining the throttle valve or carburetor slide position is a challenge on many engines. While a sensor can often be retrofitted to the throttle shaft of a modern throttle body, usually requiring considerable modifications, the situation is significantly more difficult with classic carburetors. Suitable mounting points are often completely lacking, making precise load signal measurement virtually impossible. This is exactly where the MD-Lambda-View cable pull sensor comes into play.

MD-Pico, the display for MD-Lambda-View in matchbox format

MD-Pico is a mini-display, specifically designed for MD-Lambda-View, and is about the size of a matchbox. It is extremely compact, lightweight, and perfectly suited for test drives. Despite its small size, MD-Pico offers powerful features and also functions as a mobile lambda data logger. MD-Pico has an SD card slot, through which all important engine data is permanently recorded as soon as an SD card is inserted.

ABOUT ME

I'm a qualified engineer, a passionate motorcyclist, and a keen mechanic. Whenever possible, I try to do all the work on my bikes myself. It's always bothered me that there isn't a "tiny" module on the market that displays the engine's lambda value in a simple, straightforward way. Everything currently available is either too large for my needs or lacks the necessary functionality. That's why I developed MD-Lambda-View.
