9) Setup: Idle
Set the Idle Activation Criteria (the default settings may be sufficient for initial
startup). Note the other options should be adjusted when the engine is running.
10) Setup: Engine Protection
a) Set the “Max Boost Limit” [kPa] to enable a 100% fuel cut if the manifold
pressure exceeds this value under any conditions.
b) Set the “Overboost Allowed” [kPa] for use with variable boost targets. The fuel
cut will be dynamic and will be dependent on the target boost setting. The fuel
cut will activate if the manifold pressure exceeds the following value:
BoostTarget [kPa] + OverboostAllowed [kPa]
Both of these setting should be configured to ensure proper engine protection
under any overboost circumstances.
c) If an oil pressure sensor is connected, “Oil Pressure Protection” can be enabled.
d) Select “Lambda 1 Protection Enable” if an AEM sensor and harness are
connected to the ECU. Set the activation criteria, and then select “Lean Fuel Cut
Enable” and/or “Lean Spark Cut Enable”.
InfinityTuner: Basic Tuning Guide
The following basic tuning guide is intended as a quick start guide to tuning with
InfinityTuner and is not designed to be a thorough tuning instruction manual. For more

Infinity: Flash Memory Functions
Changes made to calibration tables are stored on the ECU in a temporary memory
location and applied immediately. In other words, while tuning live, all changes take
effect immediately. They are not however immediately saved to ECUs flash memory.
The menu function Target – Commit modifications (Hot Key – “CTRL + SHIFT + C) is
used to save all current changes to the flash. This feature allows the user to choose
what changes to save to the ECU during a tuning session. Target – Revert
modifications (Hot Key – “CTRL + SHIFT + R) removes any changes not previously
saved. At key off, the system will automatically commit all unsaved changes if the Key Off
Commit option is selected in the Tuning Preferences Wizard page shown below.
