I have looked at the Helm Manuals website as I would like the pin out info for 2006 58X reluctor wheel LS2 with E38 ECM. But it says that the 2006 info is not available yet.
Any American dealers that have a manual or wiring info for sale, or anyone who has the ECM pin out details to share?

Thanks

Do I gather that this info is simply not yet generally available, or is it a real big secret!
Here's hoping

From what I remember GM switched to the 58X reluctor wheel on the LS2 mid-year 2005 (or sometime during the model year production run). If the 06 manuals are not out yet, I would check with some tuners who have tuned the LS2's who may have the information.
Some sponsors here like; Katech, A&A Corvettes and others have tuned these cars and might be able to help.

 

I can get you the pin out, but what vehicles were the E38 pcm's used with? GM does not refer to them as E--. Just service numbers by vehicle listings.
