IMPORTANT BACKGROUND INFO
The Infinity platform is very different from previous generation AEM EMS products. The
hardware (circuit board assembly) is designed around averyadvanced automotive
grade microcontroller (processor or “chip”). Several layers of software reside on this
chip that allowfor real time firmware programming without the need to write computer
code. This technology hasallowed AEM to develop advanced control modelsnever
before usedon 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 andfeel is very different and it may take some time to
adjust to the newtuning environment.
Our new tuning tool, InfinityTuner is alsoabrand new product built from the ground up
to interface with the new hardware. It features amodular design that allowsusers 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 InfinityTuner SetupWizard “plug in”
is acompletely stand-alone application that will evolve with InfinityTuner. It is much
more integrated with the ECU hardware and performscomplex validation checks for all

RevC 07/15/13 Page 4
requested changes.
Among other things, InfinityTuner is apowerful math processor. Special features allow
usersto create completely custom conversion channelsfor table data. Virtually any
function can be employed to display data in different formats or units. Math functions
are alsoused for table edits. ANY MATH function can be usednot just alist of pre-
defined selections. Advanced userswill really enjoy the flexibility thisfeature adds.
Abuilt-in logging playback/controls synchronization feature allowstuners to view live
plot data and make changes to their calibration values on the fly, knowing exactly where
the ECU wasaccessing table data. For more detailed post processing of data, AEM
offers itsnew analysis package, AEMdata.

similar displacement, sensor setup, and injectors. Every vehicle must be tuned before
use.
1) With the Ignition in the ON position and InfinityTuner Running, click on the
Connection menu item and select Connect to USB from the dropdown list. A
progress bar will be displayed as the laptop gets the calibration info from the ECU.

have a .itlyt extension and should be saved in the My
Documents\InfinityTuner\Layouts folder.
3) Save the session file by selecting File –Save session. Session files have a .itssn
extension and should be saved in the My Documents\InfinityTuner folder.

InfinityTuner: Setup Wizard
Setup Wizard
The ECU setup wizard is designed to simplify the initial configuration of the Infinity ECU.
AEM recommends using the wizard only when connected to the ECU via USB
with the power on. Most of the setup wizards require the engine to NOT be running.
Exceptions will be clearly stated in the function descriptions.
The setup wizard contains general and detailed descriptions with each major function.
The most imperative functions are discussed below. Use the descriptions in the wizard
to assist in the completion of all other setup features.
1) With the laptop connected to the Infinity ECU via USB and InfinityTuner connected,
Go to the Plug-ins menu at the top of the InfinityTuner layout and select Wizards >
Setup Wizard.
2) Setup: Basic
Select the appropriate engine descriptions for Displacement, Number of cylinders,
cycle type, Ignition type and firing order. Choose the following Airflow Calculation
Method: VE (using MAP sensor), 0-5V MAF (analog MAF sensor), or Frequency
MAF (Digital MAF sensor). Then describe the Load Axis vs. RPM for Main Spark
Map and VE Table (if using VE for Airflow Calc Method). MAP [kPa] is a typical
selection for most cars using the VE airflow calculation method.
3) Setup: Cam/Crank
Choose the Cam/Crank timing type that will be used. The description field notes
important information about edge selections and wiring requirements.
4) Setup: Ignition Sync
The Ignition Sync is used to ensure that the timing measured at the crankshaft
matches the channel displayed in InfinityTuner. This step is crucial and must not
be skipped.
Two separate procedures are required depending on the Infinity application: Plug
and Play, or Universal Application.
Plug and Play
a. In the Ignition Sync wizard, select the checkbox “Lock ignition timing at” and
set the “degrees BTDC” (10.0 deg BTDC is the default).
b. Start the engine and use a timing light to verify that the crankshaft timing
matches the locked ignition timing set point (10.0 deg BTDC if using the
default setting).
c. If there is a deviation between the locked set point and the actual timing
observed with the timing light, use the Sync Adjustment arrows to match the
wizard-displayed value with the actual value. As the Sync Adjustment arrows
are advanced or retarded, the timing observed on the crankshaft will change,
while the “Lock ignition timing at 10.0 degrees BTDC” will remain constant.
