Fully agree, VIDA is the best way to go in my opinion (there's a sh*t-tonne of good information in there). And you're asking the perfect questions as a "new" XC90 owner, congrats on your purchase.

Link here VIDA 2014D - Installers, EWD, Virtual Machines & Other Resources | SwedeSpeed - Volvo Performance Forum for information on getting it running on a PC either standalone or virtual. The interface to the vehicle is DICE which plugs into the OBD port. If you're going to make an investment in your vehicle, this is one very good place to start. VIDA has every single thing you'll need to maintain your V8 other than the tips along the way (those are more often back in the "How-To" sticky-OFFICIAL: XC90 Part Number & "How to" Thread | SwedeSpeed - Volvo Performance Forum .

But get VIDA downloaded and running while you figure where to source a DICE, that way you can start reading up.

**If anyone knows the person selling the "ready-made" setup, maybe PM a name. It might already be in the VIDA forum above.

Lots of folks can help you with your 2007 along the way. This is one link that was started on the V8 but was never really kept up- V8 (B8444S) related information

Good luck with your V8 and welcome to Swedespeed.

@Danny Pritt , the V8 alternator has a default 13.9 VDC output when it's not being managed by the ECM/CEM (either or both can manage the Alternator Control Module). Physical connectivity is a single green wire from B1 terminal (B2 in connector not used) on the ACM to A:25 terminal on the ECM. ACM is controlled via LIN bus to manage output voltage.

I cannot recall the posts as they're pretty far back but I've seen a few where the alternator was the wrong part. As noted above, if this is not a Volvo part or a genuine Bosch AL0821X, it's anyone's guess which is at fault to prevent the ACM from managing the output. Great that you did the valve cover gaskets and there is a good amount of informaiton in the "How To" sticky specific to the V8. A running copy of VIDA is the best single resource for this vehicle, you can find it on the site in the OBD forum. Well worth the time and effort to source and get installed.
