The Autronic analyzers will display either air fuel ratio or lambda. Select between the following fuels for air fuel ratio display, Gasoline, Diesel, LPG, Alcohol.

Analyzers control the heating of the sensor and display a corrected output to the screen, based on sensor temperature.

These analyzer are supplied as standard equipment with Dyno manufactures.

Both models provide a corrected 02 output that can be used by a ECU or data logger. To use this feature requires a Pwr/Log cable to be ordered with the analyzer or modify the existing Pwr cable as per the example in the manual on the Techdata page


There are two models of the exhaust gas analyzer.

A Model: Uses a Bosch four wire wide band sensor and has a air fuel ratio range of 10:1 to 36:1. This analyzer is ideal for 90% of all tuning requirements.

B Model: Will use a wide band Bosch sensor or a UEGO high precision sensor. The high precision sensor will update every 0.10 of a second, it is more accurate than the Bosch sensor at very rich or lean air fuel ratios. It also has a air fuel ratio range from 9.0:1 to 75.0:1.
