Log File Analyzer - Version History
v11 – September 24, 2013
Changes were made to eliminate all samples where Injector BPW = 0. This was done to better report Average BLM and INT values because BLM and INT values are frozen in sample data at the value immediately before BPW goes to zero during deceleration:

• Injector Tab
  
  • Now reporting both Batch Fire and Sequential Fire Duty Cycles
  • Now showing Averages of Battery and Pump voltages as well as Time Between Reference Pulses without regard to BPW=0
  • BPW Min and Max values show zero if all samples detected have BPW=0.
  
  
• VE Tables Tab
• Added section of VE tables for BLM and INT that excludes samples where BPW=0. Not eliminating these samples has the potential of distorting Average BLM and INT values.

v10 - August 17, 2013

• VE Table Fueling Tab
  
  • Both Upper 3D VE Tables were incorrectly in Lower VE Table format. Can’t remember why. Likely because copy and paste was used to easily create the Upper tables once the lower table was developed.
  • Minor formula errors were corrected in both of the 3D Upper VE tables. Apologies to those using the upper table BLM and INT values for VE Correction. The “Average VE Table Change Factors” in the column to the left of the VE Tables are correct and did not require change.
  
  
• VE CORRECTION Tab
  
  • This new Tab was added to the right of the “VE Table Fueling” Tab to allow copying of data from this new Tab to a VE Correction Spreadsheet. Data cannot be copied from the VE Table Fueling Tab because it is Protected to avoid inadvertent formula changes

v09 11/21/2012

• Analyzer now provides 3-D VE and Spark Tables in TunerPro format. Each cell of a table that was accessed during a logging session shows the average BLM or INT value (VE Tables), or SA-TDC value (SA Tables).

• Uploaded with this post a Speed Density Log File Analyzer program I’ve been working on and using for several months. It automatically reads and analyzes all samples in a TunerPro log file and presents the analyzed data in BLM Table and VE Table formats. BLM and INT Change Factors are provided for use in quickly adjusting the VE Tables based on RPM and kPa. Other data are also provided to aid in tuning.
  
  Would appreciate your feedback.
