Well....my Cobra passed the IM240 emissions test today!
Big thanks to Nick Ball who is the testing engineer at Vipac. Nick is a thoroughly nice guy who went out of his way to explain the whole process to me. He let me watch the test and showed me how everything works. He couldn't have been more helpful. In summary, the IM240 is not a scary event!!!
