5.0.1

given that you targeted 2500 rpm, the LTFTs from this log are calculated from only 349 data points. The number of data points making the calc is in the second tab. More the better.

This is not a good representation. Re-Log targeting 2000-2300 rpm at cruise and lets take another look....

k, you're using an old version of the app...

if I go by the older version, your average ltft's are 1.38 and 2.26.... which coincides with the info you posted...

update to the latest version please...

BriVG - uninstall the version you currently have installed...

download and install the latest version from our site...

then run that csv log file through it again...

there's no way you're getting 2.2xxx as an average ltft result...

see my post above ^^^^^

as I mentioned, when I run your csv log you posted through the 5.0.0 and 5.0.1 versions, your average ltft's are at 1.32 and -1.65.... so that's why it's saying that no adjustment is necessary...

cuz your lowest bank ltft is already at -1.65...

if it was to say to adjust your slope to -2%, then that would put your lower side down to -3.65... which is out of the ideal range...

I went through the log manually, and it confirms both sets of results. both with the new and older versions.

so, uninstall the version you currently have installed... control panel > add/remove programs...

download and install the latest version from our site...

then run that csv log file through it again...

thanks!

My version (5.0.1) says what your saying, and i understand that> the part i don't understand is that when you look at the log maually, all steady runs at around 2500 rpm are overwelmingly 1.56 and 2.34, shouldn't they be closer to zero or slightly negative at that rpm?

Guys?

you need to re-do your log... keeping it in the 2000-2300 rpm range...

your other data is outside of the range, and the data that is left to calculate your ltft's on is a pretty small sample set.

re-do the log and let's check it again...

Why is the range between 2000-2300 rpm?

Post by **06MonteSS** » Mon May 12, 2008 2:38 pm

to ensure a steady cruising log, so RPM's aren't all over the place from speeding up, slowing down...

and also to have an adequate amount of engine load to get accurate/correct data...

this is the rpm range that was recommended by diablosport...

OK, here's my latest log that DSLogRedux says no change is necessary. Cruise is at about 2280 rpm (cruise control), when I looked at my predator every few moments the ltf's were at +0.78 each, from that wouldn't you adjust -1? I know what the program says is the averages (not +0.78), but my manual look see at the data (cruise portions only, not every time the rpm's went through the specified range either up or down) gives the +0.78 as the outcome.
Am I too picky in my data point selection, or am I overthinking this?

Thanks again,
Brian

your average ltft's are at 0.33 and -0.57.... your log is one of the very few that are ever that close to being right at 0... so that's why it does not recommend any change...

you can leave your settings as is, or you can go -1% to make them -0.67 and -1.57 - it's up to you. But you do not have to.

the cruise data csv file is attached below, so you can see the range of data that is used to calculate the results.

Thanks Monte!
