for those of us who are not engineers, can you explain that to us?


thanks!

And where did you get the software for the Skyline style Commuting Log? That's awesome! Can it record G-forces or anything like that?

 

Fifth gear aside, I'm jealous of the 5 1/2 minute commute.

Aside from no appreciable heatsoak after idling for a minute, and the fact that you live really close to work, what's the run through the gears (not all of them though) mean?

The boost plot is strange. It looks like 500 mBar is equilibrium and you're only getting spikes when your foot's in it. Just don't get that one...

You have the new temp diff. gauge in yet?

Andy,

Do you have the boost values for the Y-axis? Also do you have a higher resolution plot? It would be nice to see it in 5 second interval instead of 25 second. I know we are picky.

Were the sensors calibrated against NIST traceable sources? :smile:

 

Well, I'm in 6th gear now (or at least I should be).

RCristiano,

That was logged with prototype BiM-COM software:

friedduck,

My commute is 1.4 miles, averaging 4-6 minutes depending on lights. Absolute pressure in the manifold is about 500 mbar at idle.

I saw the thread title and thought you broke your transmission and I was worried that the torque of the 19% was what caused it - I'm glad I was wrong
