Ok... what's so wrong with JWT's maps? The reason they turn the knock sensor off, is because a lot of times, it will pick up inadvertant noises and interpret them for knock. The 95 and up sensors are even worse than the older obd1 sensors. I've never lost an engine with a JWT ECU in it. All you've proven is what everyone has already said.. JWT is very conservative.
