Please help with analyzing a data log
I know this is the n54 section but it seems like nobody in the n55 section does any custom tuning, this board just has a lot more enthusiasts.
http://www.datazap.me/u/tke344/e40-r...18-19-20-21-22 The beginning is a little odd in that my timing is very low, nowhere near what my table says and there's a pretty good gap between load target and actual load. I feel like it has to do with my WGDC spool table? Seems like peak boost is coming in a late. I raised the values in red a few points. I also have a drop in timing at 5100-5300rpm that I can't really explain. I'm not seeing a timing correction but it just drops off. The only thing I can correlate is that it's the same time my boost peaks. |
