Oracle is the man. I bought a Durametric and it would not work for the PDAS systyem in my 90 C4 - it would do everything else but not the PDAS system and this was news to Durametric (when I called them, they told me that they had just discovered the problem with 89-90 C4's the week before). I did return it and borrow'd the system that the Oracle has and found the user interface to be nicer that Durametric but it also would not get into the 89-90 C4 PDAS system.

Before you buy a Durametric, phone them to be sure it will work for your exact application to save yourself some shipping charges. I still need to figure out what wheel speed sensor is throwing the code periodically so if Durametric has this issue fixed, I would buy another as this would be cheaper than taking to a shop with a Hammer for diagnostics.
