To answer your question: No, I've never heard of them in all my years as an enthusiast. Maybe I've just had my head in the sand? Who knows. Maybe others have heard of them and they're fantastic.

To me though, they seem to be an obscure company with a flashy website. Quite honestly anyone with an electrical engineering degree, an interest in automotive electronics, and a large amount of time on their hands, can flash an ECU (if that ECU has the potential to be flashed).

Though, keep in mind larger companies are working on the 35d night and day. Why would this small company have beaten them all to the punch?

It makes no sense. Furthermore, their response about the warranty issue is ridiculous, at best. That's not an answer I'd ever give to a customer of mine, when dealing with a $50 to $100k asset.

So if it were my SAV, I'd purchase from a well-known company, even if I had to spend a few hundred more.
