floor(val) |
| ceiling |
Returns the smallest (closest to negative infinity) integer value that is greater than or equal to the argument. |
ceil(val) |
| exponent |

exp(val) |
| isNaN |
Checks the output of an expression to result in a invalid number |

| smoothFiltered |

smoothFiltered(val) |
| accelHp |
Calculates HP based on Acceleration rate. |
accelHp(
velocity (MPH),
deltaVelocity(MPH),
deltaTime(s),
weight(lb)
) |
| Aero Drag |
Calculates the Aerodynamic Drag |
aerodynamicDragHp(
velocity (m/s),
airDensity (kg/m^-3),
dragCoefficent,
frontalArea (m^2)
) |
| Rolling Drag |
Calculates estimated rolling resistence |
rollingDragHp(
speed (MPH),
tirePressure (psi),
weight (lbs)
) |
| Last Value |
Returns the last record value for the specified field or expression |
lastValue(anyField) |
| Historical Value |
Returns the value for the specified field or expression from n records back |
historicalValue(anyField, n) |
| Min |
Returns the minimum value resulting from 1-n expressions or variables |
min(exp, exp, ...) |
| Max |
Returns the maximum value resulting from 1-n expressions or variables |
max(exp, exp, ...) |
| Max Value |
Returns the maximum historical value for the specified field or expression |
maxValue(anyField) |
| Min Value |
Returns the minimum historical value for the specified field or expression |
minValue(anyField) |
| table |
Perform a table lookup using an inc file |
table(expression, 'fileName.inc') |
| tableLookup |
Perform a table lookup on 1D or 2D arrays based on specified OutputChannel(s) and 1D array lookup references.
It will provide the interpolated value for the relative position of the lookup.
|
tableLookup([array.valueArrayName], [array.lookupArrayName], [lookupChannelName])
tableLookup([array.zParamName], [array.xParamName], [array.yParamName], [xChannelName], [yChannelName])
|
| Accumulate |
Accumulate and sum the expression
This allows totalling distance, milage, fuel consumption, etc. |
accumulate(expression) |
| Persistent Accumulate |
Same as accumulate, except the accumulated value is persisted to the next session. Allows for an Odometer. |
persistentAccumulate(expression) |
| arrayValue* |
Gets the interpolated value from a Constant array. The right of the decimal for index expression will be used for interpolation |
arrayValue(Constant, indexExpresssion) |
| if* |
Excel style if function. |
if(condition, then, else) |
| sum* |
Excel style sum function. |
sum(exp0, exp1, expN...) |
| timeToExceed* |
Resets timer when expression is <= 0
Once expression resolves to > 0, the timer begins and will count time in seconds until expression >= targetVal expression.
Time expression is optional, if not provided the local clock is used. Thus in MLV it is required if you wish to use the Log time. |
timeToExceed(targetVal, expression, TimeExpression[optional])
Example for 0-60 in MLV:
timeToExceed(60, [VSS1], [Time])
|
| timeTrue* |
Evaluates the TrueFalseExpression and begins tracking the time it has been true (non-zero) in seconds. Once it is false, the time resets. |
timeTrue([TrueFalseExpression])
Example for 3 seconds after RPM > 600
timeTrue( rpm > 600)
|
| timeTrueFor* |
Evaluates the TrueFalseExpression, will return false (0) until this expression evaluates as non-zero consistently for the period provided in seconds. |
isTrueFor([TrueFalseExpression], [SecondsTrueExpression])
Example: Will return 0 until rpm over 600 for 5 seconds
isTrueFor( rpm > 600, 5)
