AEM Infinity Supported Applications - Dodge 2008-2010 Viper 4G - Manual (Page 3)

Infinity Supported Application 3
© 2014 AEM Performance Electronics
IMPORTANT APPLICATION NOTES
The test vehicle used for development of this app was a 2010 Viper ACR with ACR-X headers and a
deleted A/C system. Due to a lack of the A/C system and its components, operation of this system was
not verified on the Infinity EMS.
The coils used for testing were “stock” two-wire ignition coils (PN 1-05037127AB). For compatibility with
the Infinity EMS the use of an igniter or CDI that accepts a FALLING edge fire signal is necessary. For
vehicle development three AEM 4 Channel Coil Drivers (PN 30-2840) were used.
The 2008–2010 Dodge Viper uses the Push-Button as an input into the Factory ECU to control ground
for the Starter Relay. An external circuit is utilized to control the Push-Button Start to Starter Relay
interaction. A
schematic to build this device is provided in this document. Note if this schematic is
followed the Starter Motor will continue to spin while the Push-Button Start is being held. Continued use
of the Starter Motor once engine is no longer within the cranking RPM range may cause damage to the
Starter Motor, and Engine.
The 2008–2010 Dodge Viper uses a 12 Volt pulse-width modulated signal through the Generator Field
Control wire to control the Generator output. An external circuit is required to provide this signal as the
Infinity is not outfitted with hardware to support this function. A
schematic to build this device is provided
in this document.
Caution must be used when tuning Drive By Wire (DBW) values for this application. While creating the
Infinity base session, it was observed that aggressive DBW values may cause the throttle plate to wedge
between the throttle body housing when closing resulting in a DBW_Error_Fatal.
The stock CLT, IAT, MAP, Injectors, Oil Temperature, Oil Pressure sensors have been fully
characterized and their calibrations have been inputted into the base session.
The adapter harness used to mate the Infinity EMS to the stock wiring harness was setup to use the
stock main relay that is already on the vehicle. The stock Oil Pressure, Oil Temperature, Coolant
Temperature, Battery Voltage, Speedometer, and RPM gauges are not supported by the Infinity EMS.
