Gear Graph Feature for i2

Postby JayDee on Fri Feb 13, 2009 1:34 am

Hi, This is one is basically an i2 features request.
But any feedback would be good to see who else would find it useful and help justify the time it would take to implement it in i2...

Below is a sample of log data, wheel speed/RPM to give a standard geargraph.
I have then drawn additional lines onto the graph, it is these lines that I wish to replicate.
I have tried to create somthing similar in i2 maths, but I don’t think I am currently able to overlay them onto the scatter graph anyway..

The purpose of this graph is mainly for training / reviewing driver data and as a scrutineering tool.
>It should help drivers to understand their shift points.
>Quickly see where they may be changing down at the wrong point, thus dropping out of the power band
>High revs before changing may not place you into the most efficient part of the next gear.
>consistent deviation from the ideal lines would indicate an illegal/incorrect ratio being used.

I would like to be able to.....
Plot the gear lines. (lines in grey)
Plot the idealized shift sequence ( lines in green)
Plot upper and lower limits for the RPM (Line in blue)
Ability to overlay another set of log data to highlight driver differences.

Its a big ask for sure but what are the odd's? J. :)

it is a reasonable request, but I dont know when it would get done.. I will add it to the request system.
