Hello imon_2nd,
i think there must be existing programming libraries for that problem. First music industry has developed a large range of digital filters. Such systems are in cars for a longer period - for example knock sensors. And shure there are other industries where this kind of diagnosis is used.
I agree when it comes to the point when you say the engines are different and additionally the engines are not new. But the idea of the nine8six was detect change. So if i got it right, this unit can learn the state of the engine. And if anything significant changes it alarms. Problem i agree is that to detect what are the parameters for an IMSB alarm. So an idea is to bulld a database where everyone who has that unit will be connected to an internet data base and the units sends her data everytime the car was moved. So the data can be analyzed and can be a learning system. Additionally it is important that the owner gives information about his car according to the data. And also it would be useful to get an info from the owner if the car was phyically diagnosed for an intermediate shaft bearing problem or if was replaced and when and what type. If we could do software updates from the web to the unit, we could inform the unit about these parameters and also of parameters to the specific engines. So this would be more like a self learning system.
And that would be an interesting part, because if the owner has for example a failed water pump and he will tell us when the water pump was replaced, we would know OK - this data came from a failed water pump and so on.
So it would be a more collaborative system than an endless reserarch system.

PS: do we need another thread?
