Anyone written anything on how to read WINALDL data? I have the program and the cable and have been logging data but I have a hard time understanding what it tells me.

I have never really "Tuned" a car before. Every car before this one has just been jump in and drive. What columns are most important? How much knock is normal and how much is too much? When you read the data, how do you interpret it? What do you look for?

If this had been covered somewhere already I apologize I tried a search but didn’t find the answers I was looking for.

Thanks in advance

I like to import it into excel and then sort by map then by rpm and then look at the blms in those map areas to see if the Blms are to low <128 (rich) or to high >128 (lean). I also insert a line at every 10kpa since the fuel tables in the chip are in 10kpa increments.

 

Thanks for the reply it should get me started. BLM's I think I get. What are KPA's? What do they do and how do they work?

Map values are measure in KPA (metric) not inches. I am not going to try and spell what KPA stands for. Its the metric equivalent for measuring atmospheric pressure. I sort by that so I can see how the engine is running through those kpa's and know if the engine's fuel curve needs to be altered. If the engine is running 122 BLMS from 800-1600 rpm at 20 KPA and then switches to 132 BLMS from 2400-3200rpm at 20 KPA then I know I need to take fuel out of the lower rpms and add more in the higher rpms. At least that is the watered down generic version of what I use those values for but it should get you started.
