My turbo "system" was pretty crude, blow through the carb, no intercooler. The closer I got to work, the more boost retard I had to dial in keep it from knocking.

I started experimenting with knock sensors in 1982. Hughes "gave me the opportunity" to start my own business in '89. Individual cylinder knock control was released in '91.

Looking forward to the re-release of your single coil system.
