Help Understanding Logged Data

vetpet · 10-31-2005, 08:08 PM

On the weekend I did my first data log using EFILive. The data has been saved as a log file and I'd like to look at some of the different MAPS. What is the correct procedure for opening up a map for the different PID's that I recorded? Do you use the Ctrl & M function and then choose the map you want and specify the row and column values? I noticed that the other map option opens a file in EFI that has predetermined map properties. Are these good to use or should I create my own? When I opened a map for the LTFT the values were in %, not digits. Looking at the LTFT PID's there is no metric or imperial option for it. Which maps would you consider to be most useful to look at? I'm sitting at the bottom of the learning curve and it's a steep climb up!

Thanks for any help.

Download your tune or look at a stock tun for your car. Look at some of the tables you have access to, VE tables Spark tables, etc.. and see how they are linked Then log some of the parameters you are interested in. After logging, open the log file and go to maps, you will see all the parameters available that you logged when creating a map. You can then build any of the maps you want to see, some will be real data and some will be in factor or average, depends on what you select. Look at the AUTO tune PDF file on EFIlive, they will show you what some of the tables look like and how to make them.
Good luck, the ladder is not as steep as it looks at first. Welcome aboard, EFILive is a nice ride.

Thanks Purrv, Would it help me to look at some of the example tune files and log files that came with EFI first? From everything I've read so far the LTFT table is what you want to look at first but when I look at the table the cells are in % format. Can these values be converted to a positive or negative whole number? My understanding is that you want the numbers to be either slightly negative or zero in the cells so that you don't add extra fuel at WOT to the PE table. I'm probably jumping ahead of myself but do you make your cell changes in the logged map table and then copy and paste it into the tune map table for downloading into the PCM?

Thanks for helping a newbie.
