This was shipped with the Dinan CAI that I purchased here: https://www.ebay.com/itm/2000-528i-e...72.m2749.l2649

As you can see at the above link, it was advertised to me as having "Dinan tuning." I have no idea what tune is loaded, whether stage 1, 2, 3, transmission, etc. I'll let you figure that out if you want to purchase it.

I have no need for this DME, I just wanted the CAI. $65 shipped.
