RCHAD,

Ok, I spent a few hours today working with the EFI Data logging and I must say that I'm seriously IMPRESSED!! For those of us without Phil or Kris's level of tuning skill and/or regular access to a dyno, the EFI Data logging module is worth it!!! A must have IMHO.

I'll post more charts from my data results from my logging sessions showing before and after "learned" adjustments including RPM climb duration from 3K to 8K. This will be crossed referenced with both EFI data logging and my RacePak data logging.

I believe Kris provides a pretty good Lambda Setpoints (I didn't change them as they seemed to be what a FI car would want AFRs to be at) -- Turbo might be different from SC as load/rpm variances. But, assuming you have good Lambda Setpoints the learning process seems to be pretty darn bang on correct after corrections are applied to the fuel map (this is a VERY easy process).

If you plan to change your cam switchover rpms/degrees then the Data Logging/learning capabilities are a must have tool as it can adjust your fuel map to optimize your cam switchover.

I'm still giddy about EFI's data logging -- makes it so VERY easy to realize gains from just about any modifications and/or weather difference. I plan to run the same learning process on the track next month to see if track conditions require adjustments beyond agressive street conditions (I'm sure there will be some minor changes here and there in the fuel map).

I'm so happy with this EFI setup -- the "coming soon" firmware will just be more icing on the cake.

Rob.

P.S. will post the AFR/RPM/Load/IAT charts later this week
