I added a column in EXCEL.
I use the marker column.
=(C50-C46)/(B50-B46) for example. Takes RPM vs time over a 4 cell span. Smoothes it out a little. I do it through the range to see where the car starts falling on its face. Fun way to compare your car to previous logs. See effects of mods, or weather or whatever you want. Doesn’t work well to compare vs. other cars, but it’s all we have for the R8 in question so it’s fun to do.
On my B7 S4, I believe I was around 450 RPM/sec from 3k to 7k stock or something and closer to 525 when modded. I should look it up. Do we have a log thread here? I think we try to suppress this type of discussion or comparison because some dork will always log straight down a mountain and not disclose it in order to make his tuner/car look great. Of course that won’t happen here.
beemercer was thinking of writing a program of some sort that would sort out the log file for you. Not sure he still wants to.
