I was playing around with mine in my 07 f150 and was looking at the knock sensor values. According to Ken over on the MSD forums, the normal value is 0. Mine are all over the place. From 240 or so at idle in park or drive with a timing advance of 9-15, to over 600 under acceleration with an advance in the 20's. Cruising shows mid 300's with advance of 36-38. I'm not sure if there is a problem with the truck or just a glitch with the dashawk. If some with a similar setup could post their readings, I'd really appreciate it.

Thanks
