Under the seal, over the seal, I don’t think it really matters. Just use the thinnest insulated wire you can find and make more than ten coils at the base of the coil boot. Use a “connector” to transition and you can easily swap between the two or solder the connection and have a dedicated wire for each. Sounds like the main issue is getting a signal at all from the coil.
Complicating things, there’s a metal sleeve that snaps over the plug, so there might not be enough real estate for more than the three loops I already tried. Magnetic strength drops by 1/x^2, so the fat assembly might be what’s killing me. If I can get it to fit where it tapers down, that would be much stronger. Just don’t think there’s clearance even with my already thinly insulated wire.
Really though, I don’t need rpm since it has debug mode. My ratios are fixed, and I’ll be able to see shift timing in the speed trace. I can always just emulate rpm by using gear ratios, but again that really won’t get me much useful info for what I need
I haven’t tried to read the raw XRK files yet, but debug mode worked for at least getting GPS data!
Normally, the MyChron saves two different timers - one for sensor data (like rpm, EGT, water temp, etc) and one for GPS data (coordinates, accelerations, speed, etc) - and then AIM interpolates them together. I’m curious what’s going to happen when I read the data, but RS3 seems to read in the GPS data just fine. I never could get an rpm signal, so Debug Mode was a huge help @GabrieleV !
