Patches -> Read the 08 H3 Alpha's E67 brain (11/29/2007 7:29:52 PM)
|
I upgraded my EFILive V1 license to the V2 version with the new handheld controller. As I mentioned in a previous post, the new software incorporates a virtual VE table to compensate for the VE coefficients which were a pain to work with in previous versions. The VE table can be modified just like other ECM VE tables (like in my E38 vettes) and EFILive calculates the new coefficients. This means that, basically, the same techniques used to tune earlier PCM's (like the E38) should apply to the E67.
I only had time this evening to upgrade my notebook with the new software and calibrations and then do the V1-->V2 upgrade so I only did a read of the stock tune on the Alpha. Nevertheless, it is exciting how smoothly the entire process went and, of course, to see the stock tune displayed on EFILive. Below is a screenshot of the virtual VE table. As expected, there is the usual conservative tuning present from the General. Understandably, there is a long disclaimer dialogue box that comes up initially when opening this calibration screen warning the user that this is a virtual matrix generated using a polynomial that approximates and smooths the surface.
This is a new tuning learning path to wander down and fill up the the next several winter months. I'll be checking out the rest of the stock calibrations this weekend. The tranny settings are also of interest as I'm interested to see how it differs, if any, from the tranny settings I have in my wife's vette which also runs the 4L60E.
