First, I was talking about the Tech Gauge, sold by Tech Gauges. NOT the aeroforce gauge.
Secondly, I don't know how Mopar programed HOM... I just know what we saw on a s2 with toys and exhaust car. I wish I could tell you more, but its all speculation and observation of ONE car... Not enough to base fact on.

or do you believe that 5 is just a voltage value determined by the guage.
Personaly, I believe its a voltage value... HOWEVER, the head guy at Tech Gauges told me its actually degrees of timing being pulled DUE to knock. So a five value is five degrees of timing retarded due to knock. You might PM PitViper... He worked with the Tech Gauge crew to develop the Tech Gauges... He may be able to tell you more about it.

The SRT4 runs SO much timing under boost, the NGC MUST take care of itself. It probably pulls back way too much at first, then adds timing back in until knock is encountered again. It probably does that to simply protect the engine. Think of it as a child touching a hot pan... The child doesnt have to YANK its hand away from the pan, but it does. The NGC probably doesn't have to pull 5 degrees of timing, but it does to stay safe. Again, that is my OPINION... Dont take my word for it.
Plus, I think your getting some things confused... You don't see 2.5 degree's of knock... You are seeing 2.5 degrees of timing being reduced DUE TO detonation (knock).

Thats the way the head guy at Tech Gauges explained it to me.

When the aeroforce gauge came out, and several people were testers for it, that was the idea. It just assigned a value to knock based off the voltage of the knock sensor. Obviously higher values meant more knock. The guys at tech gauges tell me their gauge measure the amount of timing being retarded due to knock.

I don't know about maximum values... Id try to keep it as close to zero as possible.
Yeah, it sounds like 5 is the threashold for hom on s2 with just exhaust. But that is NOT fact.. That is an observation we made on ONE car...
