Subject:	Minutes of the Mack T-11 Task Force Conference Call of April 4, 2003
Here are the unapproved minutes of the Mack T-11 Task Force Teleconference of April 4, 2003.
The meeting began at approximately 11:10 am Eastern time.

Participants:
Jeff Clark, Jim Matasic, Dave Venhaus, Jim Moritz, Tom Franklin, Jim Gutzwiller, Lew Williams, Scott Richards, Wim van Dam, Bob Campbell, Charlie Passut, Riccardo Conti, Ron Buck, Gita Krishnaswamy, Pat Fetterman, Andy Ritchie, Greg Shank, Ken Goshorn, Steve Kennedy

Summary of Action Items:
1. Labs to provide injection timing data to Jeff Clark.
2. Labs to use oil sample purge volume of 8 oz.
3. Labs to obtain new ECUs that better meeting the fuel flow spec from Ken Goshorn.

Review of Tests and Data:
ExxonMobil is running a reference that is two days from EOT. Ethyl has completed their first reference. They had to move timing 7 degrees from initial timing to meet soot window (from 14 to 7, eventually moving back to 10.8). SwRI has completed two references and has two running that will be done prior to the meeting. PerkinElmer has completed two. Lubrizol has started their first, and it should be done by the meeting. By the meeting, nine data points should be available. The data so far shows the viscosity to be breaking within a fairly tight range.
Labs to provide injection timing data to Jeff.

Procedure Questions:
After a brief discussion on oil pan leveling, no changes were made.
Oil sampling purge quantity was set at 8 ozs. 
The end of test soot window was discussed briefly. The labs indicated that the first two windows were more difficult. No changes to the windows were made. Further discussion was postponed until all the reference data becomes available.
Oil filter plugging and filter changes were discussed. No changes were made, this will be discussed in future meetings.
Ken Goshorn mentioned that labs should obtain from him a new ECU capable of meeting the fuel flow spec.
Other procedure questions will be addressed at the meeting in San Antonio.
