There are two different companies. ADS is the one that went out of business. Here's a pasted reply that I did in a similar thread about a week or so ago:
Thanks for the information. Keep in mind, however, that ADS (Automotive Digital Systems, Inc.) is the maker of the ADS Super Chip which is not the same as SuperChips Inc. Two different companies with two different products.
Those with the blue metal encased chip that plugs into the back of the car's computer have the product from SuperChips Inc, which is still in business. I haven't seen an ADS chip in person, but it appears from their web site that they are red. The similar names has brought confusion to the industry, I'd say.
