I just now spoke to the GSCA the scan tool comparison deal. Naturally, they had never heard of the OTC's showing twice the knock retard as other scan tools. Maybe there is a little bias there, maybe not. I do appreciate your input Dave, & I tend to agree with you because this is not the first time I've heard that. Even if that is the case, it still doesn't explain why the knock gauge shows absolutely zero knock & the OTC shows 10 degrees. They are both reading off of the ecm, even though the gauge, as Rich mentioned, is spliced directly to the sender wire. I suppose the only way to check this thing out further, is to try & borrow TurboLink from a local buddy & compare the findings. If & when I get this done, I will post what I found. Thanks for the help guys.
