Yeah thats what I thought was the case. I have calculated the spring rate and have static damper pot values as they are now, but im uncertian what the next stage of calculating WT is.

One for the PI match guru's

For reasons I won't go in to (unless you push me) I need to calculate the distance so far of the current lap.

I have a formula for the total distance so far but don't know how to 'reset' it for each lap.

Any ideas?

My current formula thingy is -

register @R;
@R=@R+([CAN Car Speed]*1609.34*0.1*5/(60*60*8));
@R;

Any guidance appreciated.

Fair enough, well good luck with the end of year exams. I remember them being pretty tricky.

Its a section of my dissertation I have to do and I'm basing it on the 1275cc Locust. Rodger always uses it for tests. If you have got any more info that would be great.

i thought it would be, its either that or the MCR. I have a load of details on the locost with the fireblade engine in but the weight transfer will be different atm without it being fitted out properly and without a rollcage. I do like how it cuts out when turning right because it starves itself of fuel

Thats ok no worries. But the power point is useful so thanks for that. You on the Locoblade team then? or is this for rodger? yeah dave says that problem is sorted now, but he said that last year!

Pi Toolbox: Advanced Math

I am looking for someone who is able to help me out starting up with Advanced math scripts in Pi Toolbox.
Is there perhaps some kind of startup guide available somewhere?

I found the help function not very usefull on this particular subject.

I have to note that I basically have no real programming experience with C#.

I've merged a couple of PI threads into one, to stop this forum becoming the PI support forum

Please post questions/answers about PI toolbox here, and nowhere else.

Hello,

In our championship we need to make pitstop that last a certain period of time. Now we are working with a stopwatch mounted on the steering wheel. I want to make a math channel that starts a timer at the moment the driver pushes the pit limiter button. I want to place the outcome of this channel as an alarm or something in the display so we can remove the stopwatch and make it easier for the driver.

This for PI offcourse

Matti

PI Toolbox generally works from downloads after the event and so would not be of much use. Are you using telemetry?

Hello,

we are not working with telemetry. I thought that i could create a alarm channel activated by the pit limiter. and display thie "alarm" in the display. Maybe there is an outcome with a GPS beacon?

So this isn't a PI Toolbox question but an ECU/Data logger/dash question.

What ECU/Data logger/dash are you running?
