just FYI, I dont hear any knock at all, so if it is knock it is subtle
the wideband display is a $10 volt meter off ebay wired into one of the LC-1 outputs.
The gauge moves ALOT more when the car is cold...

The oe spot is the ideal location to measure pressure. And Scot i felt it better to be cautius in my advice as i did see the guage move abit and given the range it showed us there, i figured it was a significant variation to advise him off. Not that he would go around thinking he was 1000000000% safe and be hammering the **** out of his pistons with silent knock.

Magna, I didn't see the gauge wiggle enough to indicate detonation. The OP is very low, though. My '94 is around 85 at cold idle, down to around 30 at normal warm idle, to 25 at hot idle. WOT oil pressure is never lower than 45-50.
