Finally got the time to start fooling around with the ODBII software. Export is effortless to a .cvt file which can be read by any number of programs.

This one is two blasts up the parkway in 3rd, 4th and 5th with a wait in between.

All of the data is raw except for the boost which is inHG so I multiplied it by .4912 and subtracted 14.7. It looks a bit low but that's probably from not taking into account the barometric pressure.

In another graph I was trying to spot the advance backing off as the IAT got high but with an ambient temp of about 55 degrees I don't think I am going to be able to recreate this situation till next summer. Probably one of the reasons it has felt so strong since it got cold.

If someone would like to help me understand exactly what all of the ODBII data fields mean I would greatly appreciate it.

 

 

 

Nice graphs. Now what the hell do they mean? Andy? Eric? Anyone?
