Dustin has been working on road dyno software (designed in excel). It works but it could use some cleaning up. Any takers?

I wouldn't say I am an "Expert" but I do use it a lot. Send it to JJ_008@hotmail.com

 

I have done alot in excel plus my wife is certified in excel. i will pm you my email address

 

I've also done some work with Xecel and and VBA (Visual Basic for Applications - Basically MS Office VB). I'd also be interested in taking a look. You can send it to m1_mtkg@yahoo.com

 

Awesome guys. Thanks for being so willing to help. Attached is the spread sheet we've been working on so far. Give it a look and see if you can make heads or tails of what we are doing. Our deranged thought processes may be hard for healthy people to follow

Interesting, some questions:

1. I assume all of the datapoints were generated by the XEDE ... what format were they originally in? plain text file?

2. Assuming 1. is correct, all you're looking for then is to convert and chart the initial values, right?

out of curiosity, I see how your calculating horsepower, but where is the torque value being determined?

 

Yes, plain text file.

We have the initial values all plotted correctly, along with some formulas for Torque and HP.

 

Free Red Bull to the first person to figures that out

I almost posted how to do it....but shiv said free redbull, so i decided against it.

 

who ever decided to use black cells should be shot.

 

Using RPM and time you should be able to determine the torque value.

 

Free Red Bull goes to Jeremy.

Yay!!

 

Is it cause you only need one value to plot hp & trq due to the conversion factor? :

- HP = torque * RPM / 5252
- torque = HP * 5252 / RPM

 

F=ma or as Newton would have written it F=m*dV/Dt
