Universal cam/crank sensors
My cam and crank sensors are both doing the long, slow decline again. The cam sensor doesn't like revs above 6500 anymore. The crank sensor doesn't like to get wet.
Since new ones only seem to last for a limited period of time, has anyone tried replacing them with some aftermarket ones, like the ones from DIY Autotune: hall-effect-crankshaft-position-sensor?
If they last longer and work more reliably, I'd be determined to install two of those somehow. I have an MS3X, so the challenges should be purely of a mechanical nature.

I did not have good luck with (one of my two) DIY autotune stainless threaded hall sensors. I'm running their plastic/lug mount sensors currently. I do not have many miles on them so the jury's still out on them, but the max temperate spec is higher for the plastic sensor. Go figure.
MSD has sensors with built in LEDs that flash when it triggers, for quicker diagnosis when things go wrong. But they cost a lot more than the DIY.
I would think OEM sensors are more reliable than aftermarket sensors however...?

And I'm pretty sure the DIYAutotune's can be bought from Newark Electronics for cheap, but in quantity of 10. I found the newark part number in some old Megasquirt documentation.
Buying the sensor off Amazon from DIYautotune was cheaper than buying directly off DIY's site.

I am currently using, and have been using, genuine Mazda parts from the dealership. So my empirical evidence is that stock Mazda isn't all that great.
My MS can handle pretty much any input signal, but it may require a change on the PCB. So if I'm replacing my stock Mazda sensors with something else, all I'm asking for is that it lasts longer than a year. And I don't want to modify my MS, just to figure out that the sensor I'm using is no better than stock Mazda.
You can also get Bosch sensors from VW and such for cheap. I believe they are Hall sensors too. They run around $20 or so. But again- nobody seems to know, if they are any good.

NB cam sensors are notoriously bad, but the crank sensors are bombproof - between my own customers and all the 949Racing cars I've wrenched on, I've never seen one fail. I'd look at your ECU, not at the crank sensor.

So I doubt it's the ECU.

I have some Omron proximity sensors laying around (god knows why), PNP, NO, 5-30VDC and threaded body. P/n E2E-X1R5F5-G. Any reason they can't be made to work with an MS instead of buying new sensors every season?

Specs for the ones I have:
The 85C might be a bit low for our applications perhaps.
Response frequency 2 kHz
The response frequency is an average value. Measurement conditions are as follows: standard sensing object, a distance of twice the standard sensing object, and
a set distance of half the sensing distance.
a set distance of half the sensing distance.

Does anybody have any idea why the CKP would fail when I drive through a puddle? The connector looks good to me- but it is a 15 year old car....
