Infinity User Manual
The Infinity is a tool that allows the user to custom tune an engine by specific requirements. This
is extremely useful and usually necessary when upgrading the engine for maximum performance,
especially if installing a turbocharger, supercharger or building up a normally aspirated engine.
The Infinity completely replaces the factory ECU and features unique plug and play technology,
which means that each system is configured especially for the make and model of car. There is
no need to modify the factory wiring harness and in most cases the vehicle may be returned to
stock in a matter of minutes. The Infinity Tuner software is configured to work with the factory
sensors and equipment, so that there is no need for expensive or hard to find sensors making
replacement and repairs as simple as with an unmodified car.
Background
The Infinity platform is very different from previous generation AEM EMS products. The hardware
(circuit board assembly) is designed around a very advanced automotive grade microcontroller
(processor or “chip”). Several layers of software reside on this chip that allow for real time
firmware programming without the need to write computer code. This technology has allowed
AEM to develop advanced control models never before used on other AEM EMS products.
We’ve listened to our customers over the years and have attempted to simplify the tuning
process by employing an airflow based fuel control model eliminating many of the lookup and
trim tables from previous generation ECUs. The look and feel is very different and it may take
some time to adjust to the new tuning environment.
Our new tuning tool, Infinity Tuner is also a brand new product built from the ground up to interface
with the new hardware. It features a modular design that allows users and developers to build
completely customized templates and even design “plug in” applications that can automate many
tuning tasks. Unlike previous AEM Setup Wizards in older products like AEM Pro and AEM
Tuner, the Infinity Tuner Setup Wizard “plug in” is a completely stand-alone application that will
evolve with Infinity Tuner. It is much more integrated with the ECU hardware and performs
complex validation checks for all requested changes.
Among other things, Infinity Tuner is a powerful math processor. Special features allow users to
create completely custom conversion channels for table data. Virtually any function can be
employed to display data in different formats or units. Math functions are also used for table
edits. ANY MATH function can be used not just a list of pre-defined selections. Advanced users
will really enjoy the flexibility this feature adds.
A built-in logging playback/controls synchronization feature allows tuners to view live plot data
and make changes to their calibration values on the fly, knowing exactly where the ECU was
accessing table data. For more detailed post processing of data, AEM offers its new analysis
package, AEMdata.
