@Adoniram:
Here are some things that would have been really helpful to me this past week and may be worth adding to your first post.
1.) After flashing with the first base map, my ECU reset my IAM to .75 which is common after a new flash. You want your IAM to 1.0 before you log your pull.
1.a) The quickest way to get your IAM to 1.0 is to WOT in 2nd to redline and shift to 3rd, WOT to red line. I had to do this 3 times to get my IAM to 1.0.
2.) Help tip: Not sure if this is the case for all models, but on my '08 LGT, the rear defrost button toggled the log file. Much easier than reaching over for the F1 button in my opinion.
3.) In "Selecting your parameters to log", I was not given specific instructions on what would should be logged. fultonhow provided me with this information from his E-Tuner.
Thanks to fultonhow and m sprank for sharing this info.
HDTurbo suggested I also added Boost Pressure Actual (PSI) to my log. Please confirm, but from what I can tell, this value when logging needs to be adjusted for apsi, or atmospheric pressure. At sea level, I believe you need to subtract 14.7 psi from the recorded value. For me at ~3,000 above sea level, 13.2. I found this info here. I didn't want to add too many parameters for fear of slowing down the data stream and therefore lowering my capture resolution of data, but adding this additional parameter created no ill effects.
4.) Stay WOT until the power cuts out. The rev limiter kicks in after 6500 RPM so just commit until the rev goes down then stop your log. I have never spent too much time at red line so I had no idea there was a rev limit set on my '08 LGT.
Again, these are some things that I learned through this process and it might be beneficial to someone else.
Nice write up, by the way. Thank you for your contribution. It did get me started!
