best bet would be to have your tuner go over the logs to interpret the data.

monitor spark and see if it is pulling timing at WOT.

It shows it is voltage since that is how Fird measures it, those PIDs are designed to be useful to a Ford technician, we simply make them available to you should you choose to monitor them.

I know what knock is an does.
I just need to convert the knock volts it to ad.

On a dodge LTknock and STknock is read in degrees. But not on a ford on the diablo knock is in volts.

Thats the thing, its not 'on the diablo', that is raw data from ford, thats how their PCM displays it.
If you plug in a Snap on tool, or a Ford scanner, it will show you the same thing, its not something 'we' did.

Good find Lew.
I saw that link in the search results, but did not have a chance to look it over.

FWIW, if you live stream to the DV, you will be able to select DMRs, and there should be the described KR PIDs in degrees.
