Re: What all should be changed with a custom tune? Pretty much *any* function that the PCM controls can be changed. Timing, fueling, anyone of dozens (hundreds) of characteristics can be altered.
The following is stolen from www.carputing.com (it is a partial list of the functions that can be altered using their software).
Here is a short list of some features of LS1-edit:
Engine Control:
Limiters:
four Idle Speed Tables
Five RPM Limits
RPM limit By Gear Table
RPM Limit by Temperature
RPM Limit Delay
Fuel:
Fuel Air Ratio Table
Volumetric Efficiency Table
MAF calibration Table
Fuel Pressure versus voltage
Fuel Injector flow rate Manifold vacuum
Fuel injector Offset Table
Power Enrichment vs Temp Table
Power enrichment versus RPM Table
Wide Open Throttle Hot & Cold Tables
Closed Loop Enable vs Temperature
Timing:
High and Low Octane Spark Adv. vs RPM vs Load
Base Spark Advance in Gear, and In neutral Tables
four Knock retard Tables
3 Torque Management tables
6 Knock Learn Parameters
Maximum Torque Parameter
Engine Diagnostics:
You can change the mode of 64 different Diagnostic Tests
Transmission:
A4 Shift Speed
Normal Mode Shift Speed vs Throttle position for each Up and Down Shift
Performance Mode Shift Speed vs Throttle position for each Up and Down Shift
Wide Open Throttle Shift Parameters
A4 Shift Firmness
Force Motor Current vs Temperature vs Throttle Position
Desired Shift time vs Torque for each Up and Down Shift
Torque Reduction vs RPM
TCC lock tables
Normal Mode TCC lock speed for each gear by Throttle Position
Performance Mode TCC lock speed for each gear by Throttle Position
Cruise Mode TCC lock speed for each gear by Throttle Position
Normal Mode TCC release speed for each gear by Throttle Position
Performance Mode TCC release speed for each gear by Throttle Position
Cruise Mode TCC release speed for each gear by Throttle Position
M6 CAGS
Six control parameters
System
Fan Temperature
VATS disable
Speedometer
Gear and Tire size scaling
Speed Limiters
