I’ve done a few tests with the Due. I haven’t been able to start the car with it in place. Several different versions of the code that are meant to read in and write out the signals unchanged haven’t worked. The car won’t start. Fires at the wrong time. I scoped one channel at a time. I could only tell that the modified signal is noisier. Maybe I can use a two channel scope this week and see both signals in real time. If I could log the pins on the arduino with a time stamp that might be easier.
Since I don’t have access to the scope very often I’ve been looking at raising the compression. I think the mechanics will work out with d16 parts, but not yet sure about timing.
