I have a tune from Tom for my 09. I have done a couple of datalogs for him so he can get my A/F ratio within the proper limits @ WOT. The problem is when I run multiple PIDs in Livelink, the analog channel (A/F) gets "noisy". The gauge stays at a solid 14.8, but in Livelink the ratio jumps from 14.8 to 10 at every timestamp. Now, if I only run 2 or 3 PIDs, say A/f, RPM, and fuel pressure, the A/F stays steady and matches the gauge.
Copied from a thread by PSUrivie, due to the fact that I'm having the same problem logging my '09 with Livelink 6.1 and X3 on Windows Vista.
