Yeah just using some very general examples, not knocking traction control, their system, your interest in them, or anything like that. PS the O2 heater control I spoke of was just for the regular, switching O2 sensors.
As for knock control, I question how anyone will bless the system as truly working correctly. Or even how the box will interface correctly in an analog electronics sense. For an analog interface we'd need to know- are the stock knock sensors flat response, resonant, highly resonant, things like that. Then we need an interface, one that can filter, integrate, etc- correctly
I guess the best way to verify that it all finally works would be to instrument out an engine with cyl pressure transducers, then make it knock across the whole spectrum of engine speed and load cases and watch for it in the pressure traces and compare to the knock detection system. I can't think of any other way really. This would be a fairly big task, even at the research institute, to determine the sensor needs, design the interface for that sensor(s), design the control algorithm, then verify fully that it works But then if we don't really care that it works correctly in that regard, then why are we waiting for and paying for a system that claims it will?
If there was an external oem box that did all the analog interface and decision processing, like on the Buick GN setup then bingo, that's easy enough to get an aftermarket ecu to just listen to its output This won't be the case here I'm afraid. If the system is quiet does that mean there's no knock, or that it isn't working correctly? If it goes off was it false? But regardless, I think some of us will agree though that even with a stock GN knock system "on watch" it still won't necessarily save a headgasket or engine. Like some others too, I just switched to high octane race fuel full time and don't even try to use the knock system anymore. It wasn't working well anymore anyway with the modded engine with solid lifters. False knock all over at part throttle, silence at full throttle. I think the background noise level is just too much at wot now.
One NICE beni of the wb O2 has turned out to be that we can run C16 and the wb sensors are lasting for years in most cases I've heard. My own is 3 yrs old now and still appears to be working ok.
I agree, they have written many big checks that will take alot of work to fill. In the meantime I'll continue to race with the FAST system working wonders on my own car
