Anyone know what would cause and extremely high knock count reading, of about 700-1000 on my datamaster. Spark retard is 0. Knock retard spikes up in the 2000 range. Turbo doesn't boost past 14psi. Stock chip, 3" exhaust and pretty much stock truck. Any help is appreciated. thanks

Re: Extremely High Knock Count on datamaster
I had two situations with this.
One was a overtightened knock sensor install (my bad for not using a torque wrench) which was a quick fix.
But since your KR is 0:
The other was electrical gremlins that ended up being fuse block/cabin light related, which was a total bitch to diagnose.

Re: Extremely High Knock Count on datamaster
In old versions of DataMaster, the knock count was useful. In all recent versions it's pretty meaningless. Check out this reference I wrote:
Tuner's Guide to DataMaster
Here's another guide where I talk about tuning a truck and show pics of the DataMaster logs of what it looks reading Knock Retard at WOT:
Real World Tuning Example:
