Hey members,

Got a log file for someone to take a look at and provide some advice (hopefully). There's a few things I'm concerned with, but would like a second set of eyes to look at it.

Potential Concerns:
  • Bad MAF
  • Bad TPS
  • Bad O2s
  • Tune Issue


Issue: Sluggish Accel - after 2-3 shift and after 3500-4500rpm in any gear

Most cars I've tuned, the O2 sensors fluctuate when car goes into CL mode. This one seems to hover around the same voltage, and dips when acceleration pedal is pressed. The MAF reading looks odd as it never changes. The TPS sensor also doesn't seem to be affected wildly when adjusting commanded ETC vs Accel Pedal. The tune is a stock tune from HPTuners.
