CONFIDENCE

FWLR's products were created out of necessity. After turning his 4G63 up way too much, the factory ECU knock control went crazy. In order to push forward he built the first Knock Detective prototype. The rest is history. From his workshop, to his cars, to your project. He knows his tools will work for you, because they work for him.
