• Repeat for the maximum reading on that gauge. Write it down. The minimum value will be for -9.81ms-2

(-1g) and the maximum will be for +9.81ms-2 (+1g).

• Repeat for all three axes.

• Return to the Generic Sensors screen and turn off the three inputs you deﬁned.

• Go to the Accelerometer dialogue and enable the three inputs and enter the pairs of calibration data you

captured.

• The process is now complete, and in future the acceleration will be recorded in datalogs as accelX, accelY,

accelZ.

7.8.6 Traction control settings

The MS3Pro offers several strategies for traction control:

• VSS Slip %: The MS3Pro compares a speed sensor on the driving wheels to one on the non-driven wheels,

and reduces power if the driving wheel speed exceeds the non-driven wheel speed by a speciﬁed amount.

• Perfect Run: The MS3Pro monitors a single speed sensor. You specify the maximum speed the vehicle can

reach in a given amount of time, and the MS3Pro considers any acceleration faster than this to be wheel

spin and engages traction control. As this strategy is intended for drag racing, Perfect Run traction control

requires starting with launch control active to engage.

• Perfect Run RPM: A variant of traction control for racing events which do not allow the ECU to monitor

vehicle speed. In this mode, you specify the engine RPM as a function of time. The MS3Pro will engage

the traction control if the RPM increases faster than the speciﬁed curve. Like regular Perfect Run, this mode

requires starting with launch control active before it engages.

• Switch Input: The MS3Pro engages traction control in response to a signal from an external traction con-

trol module. Used on cars with OEM traction control modules which send an on/off signal, such as some

Corvettes.

Traction control allows several different responses to reduce power, depending on what features you are using.

• Retarding the spark timing.

• Using a rolling spark cut.

• Adding fuel.

• Reducing or shutting off a nitrous oxide injection system.

• Reducing boost on a turbocharged motor.
