I got the speedo cable fixed! So now I can see how fast I'm going, and technically I should have VTEC. It's still bogging, and seems to maybe be pinging? It sounds like a rattle or something, coming from the passenger side. That would make sense though, since my intake tube runs into the bumper over there. I can get 110 octane at a Shell station at home until I tune it, I was planning on mixing it with 93. Is there a way to calculate how much I should mix, or what octane number I should shoot for?
