Thanks Babywag. I have not set up the Sniper to control timing yet. This is my motivation now to be able to do so. Been thinking about buying the Hyperspark system and selling the MSD.
I just went out and measured distance from the Manifold exit to my 02 bung and its 15" if you follow the pipe (I could have sworn I had it clsoer). But it's as close to the verticle section as possible. Unless I put it on the vertical portion of pipe I cant get it closer to the manifold, which I am nervouse about now. I have never really seen an 02 sensor mounted on a vertical portion of pipe. Which is why I was asking the question. I really appreciate your help! Thank you.
