Datalogging with OFT and DataZap…any way to overlay two different logs?

[Silver Ignition]

I did some data logging on some various telemetry during this weekend's AutoX event and I'd like to see the differences graphed out.

Ideally lay over throttle % from my fastest and slowest runs to see where I improved, same with road speed and RPM.

Anyone know of a way to do this?

IMO, those data points aren't much use without corresponding GPS data as well. All you know from throttle, speed and RPM is what you were doing at a point in time, not where you were at that point in time. It might look like you were on the gas sooner in a corner when really you just got to the corner sooner and were actually on the gas later relative to the cone.

You have a point. I think it'd be better than nothing.

I'm already noticing from my slower runs is that I coasted more than I did in my faster runs (something I'm aware of and working on); you'll see 100% throttle, then 0% throttle and the speed tapers off, THEN you see the speed have a bit of a drastic drop (braking). On my faster runs you can see a drastic difference, either 100% throttle or braking, there's very little coasting, and I was able to keep my slower speeds higher.

So it's already helped me see in a graph exactly what I'm doing and how I'm doing it different and how it's making me faster, I'd just like to overlay the two...
