We've kept this one to ourselves for the most part but have been working on these pcm's for the last 6 months or so and are about to start beta testing them...this is mainly 08+ 2.2 & 2.4 applications. The first of the defs are done & read/writing has been tested internally and we hope to have it in public beta late this week so we can get some feedback over our company meeting going on next week. So if you own a cobalt or solstice/sky or what have you that employs this pcm feel free to shoot support an email with your serial number & E37 beta in the subject line so we can issue you the software update as soon as it becomes available.
Here's a teaser shot so you know it isn't vaporware
Because it is so closely related to the E38 pcm's we already know and love nearly all the tables translated over without much fanfair so you'll have access to around 600 or so tables/constants and switches so more than enough to keep your head spinning for at least a little while
