I appreciate it, don't want people confusing mine with yours

Here is how i save my stuff.

Folders laid out like this

Year
+--CarModel
+---CustomerName
+---Date
+----- time_and_dynorun.dat - cal
+----- time_and_dynorun.txt - notes about cal


I'll add to your tips by saying, learn to tune in lambda, lambda 1.0 is always lambda 1.0 regardless of the fuel type used, then you don't have to convert it.

If you tune on a cell by cell basis either on steady state, street driving or whatever, don't just select the whole or large block of the map and apply the smoothing algorithm to it to interpolate/smooth out what look to the human eye like disagreeable bumps, since you'll have just wiped out a lot of the work you just did, if it was correct on the dyno, don't worry if it doesn't look right ( obviously this isn't including glaring errors, but this shouldn't be fixed with a smoothing algorithm either).

If you're not steady stating and you're just working through the map quickly it might be of some use, but the ECU already interpolates those values, and there is nothing a smoothing algorithm knows about your engine.

Reset the map, set the rpm/load, correct the cell to the right lambda, next load point, copy over that column to the next column and repeat, do fuel then spark, don't tune for detonation since power normally drops off before you start to detonate, so you can tune by that power loss instead.
