It started with one car and a part that didn't exist anymore.

We bought a 2006 Cadillac XLR-V knowing it would need work. What we didn't expect was how many of its parts simply weren't made anymore — chief among them the Folding Top Control module, tucked into a low corner of the trunk where water finds it and ends its life.

With the module discontinued and no real replacement on the market, the options were bad: hunt for a used unit with the same flaw, or live with a top that won't move. So we took the harder path — we reverse-engineered the module, documented exactly what it does, and built a new one. It worked. And it turned out a lot of other owners were stuck in the same place.

That's the whole idea behind Digital Horsepower today: take the discontinued electronic modules that strand good GM vehicles, understand them down to the component level, and manufacture honest replacements. Fewer cars parted out over a single dead circuit board.
