AutoTune
The AutoTune will tune the engine with no input from the operator. To do this
there is a closed loop target air fuel ratio table, that you edit and input the
air fuel ratios that you require at the various engine RPM and Load points .
Autronic exhaust gas analyzer is required to be connected to the ECU O2 I/P. This
input is configered as the actual air fuel ratio. As the engine is driven through
the
various RPM and Load points the AutoTune algorithm will adjust the volumetric efficiency
entries in the main fuel map to "Hone" in on demand air fuel ratio.
During the AutoTune process you do not need to engage with the keyboard.
When tuning is complete, you can go directly to the Air Fuel Ratio table and
enter the new A/F ratio at any RPM/Load site. Providing you make no
changes to the physical engine, intake or exhaust, then you need not alter the
volumetric efficiency entries.
If you do modify the volumetric efficiency then you will need to use the
analyzer to AutoTune the engine again.
The AutoTune is much faster then a good operator. It is not possible to manually
tune as quick as the AutoTune. A typical engine will take less than 20 minutes
to fully map on a engine dyno.
I have tuned many engines in my business and it is AutoTune is an indispensable
tool.
Overview
Autronic "AutoTune" software provides rapid hands-tree tuning of
Engine Air/Fuel mixtures. This automated operation frees the engine tuner,
allowing total concentration on safe engine/dyno operation. On road tuning of
motor vehicles is even possible.
This software uses a complex combination of math, including statistics,
trigonometry and fuzzy logic to intelligently adjust the fuel delivery tables.
Initial tuning is rapid usually occurring within 1 second. High precision can be
achieved by allowing the "AutoTune" to operate for an extended time at
each engine operating point. The operator has control over the balance between
tuning speed and accuracy. Accuracy is ultimately limited by the accuracy of the
attached Air/Fuel ratio measurement equipment.
The program provides visual indication of the tune status. Any
programmable alarm conditions will indicate and sound if requested in
status bar. Automatic and manual storage of tune status allows the user to
monitor the tuning progress even if undertaken in several sessions. Tuning
usually proceeds 2 to 5 times faster than possible by manual means. Fuel savings
of as much at 90% have been reported. The considerable savings in engine life
are obvious.
This program also has elaborate diagnostics facilities and allows
simultaneous operation of the ECU internal data logger and external PC data
logging.
Versions will soon be available that have live engine operating data graphs
while tuning, and a live 3D graphical presentation of the tuning process.
Old modelECU's can be upgraded with a chip change and new software
