% of time you at at 100% Throttle

[twister95]

Hi,

I am wanting to show somewhere the % of time you at at 100% Throttle for the lap/selection/session somehow...

Im sure it is easy... any ideas welcome.

Thanks, Kelvin..

Yes you just use the stat_mean function in the i2 Pro maths.
stat_mean('Throttle Pos' [%] > 95, 1, range_change("Outings:Laps"))

This finds the average of the condition 'Throttle Pos' [%] > 95. So if the TP is 100% all the time the average would be '1'. half the time the time the average would be 0.5 etc.
The 1 in the equation is just to say calculate this all the time, and the range_change("Outings:Laps") resets the average each lap. If you want to reset on each section you can use range_change("Outings:Laps:Track Sections").

Set the quantity to Ratio, the display unit as percent and result unit to ratio. This converts the ratio to a percentage.

Hope that is what you are after?

Regards,

Thanks Darren, I have not used the maths functions much, but this looks good.

So to display the results, if I go to the normal views, and add a "channel report" and then add the field "100% Throttle" which I have created, and select "Max" that shows me a value, which I can take as the % correct?

Cheers, Kelvin

HI,
Is it possible to do this in I2 Standard.
I tried this example but it didn't seem to want to save the formula.

Thanks
Paul

No, i2 Pro only. The i2 Standard maths is only basic.

In the channel report, if you are viewing the report for laps then use the average (avg). The value is constant for the entire lap, but changes on the sample point that may not be perfectly in line with the beacon marker, so using the min and max may be from the next or previous lap, or even an interpolated value inbetween.

You can just veiw it on a time/dist graph as a channel, like i said it is constant for the lap, unless you are looking at sections ofcourse, then you might look at the min or max?

Thanks but I don't understand the second part of your answer. How does this relate to using I2 standard and getting % of lap that is at full throttle or even something close?

Thanks
Paul

[DarrenR]

Sorry for the confusion prule, the answer for you is to upgrade to Pro, you can't do this in i2 Standard.

But if you have a dash you can make a user condition that is true when > 95% TP and log that. Or a hundred series ECU make an Aux Table that is 0% at < 95% TP and 100% > 95% TP. Then the average of this channel you can see with the 'Show Measurements' and this is the percentage for what is shown on the time/dist graph.
Or if you have an ADL/2/3 you could do the whole calculation in the dash and just log that.


The second part of my reply above was to answer twister95's question.

Darren,
Where is the "show measurements" ?

Hi,
I'm getting the data from an M48 pro. The I2 Pro version doesn't want to read these log files but the standard version does.
Is there any way to get I2 Pro to read M48 log files ?

Thanks
Paul

The M48 and M4 do not have Pro logging upgrades....

Only the M8 and M400, 600, 800 and displays and the other loggers.
