I agree M8, but the sales stats on these are really very low when you consider the number of models this exact particular sensor does over the past 23 years in 15 different Mazda Models.
Yeah, we might as well duplicate everything electrical in a parallel as a back up.(way overboard and just a nonsense for a road car)
And the answer to OP is no.
And there is still no point in adding/designing/adapting another e sensor, making two for RX-8... even for 'back up', they don't fail.
Your point is?
What an ignorant statement. They do fail. If they didn't, why do they get sold at all? Stop contradicting yourself.
It's an aircraft, we're not talking about road car applications. Why WOULDN'T you want two of everything in something like that. If an ESS fails on a road car, you coast to a stop, if it fails in an aircraft you could die.
Even pro level endurance race cars have two of almost every critical sensor on the engine. They even common to have two starters or two alternators...

MY reference was to the RX-7 which uses TWO, OK.
I could not care less what it is used for, I am not going to sit back and argue with you, or am I going to let you talk to other members in the manner you are..
Molson, is there any reason you couldn't just run a second position plate/sensor combo on the back end of the engine, and just failover to that one? You wouldn't have to do anything coding wise other than detecting the failure and changing the input. It would even work with a stock ECU if you end up going that way.
Legot, thank you for a positive post. Not sure what all that other noise is about. We are thinking about adding a generator/ 2nd alternator on the flywheel end (PSRU gear reduction unit to bring the high RPM's of the engine down to propeller RPM's). I'll keep that in the back of my mind we could add a sensor there, thank you for the positive comment.
I feel bad for asking a simple question. I know I didn't give the full details of why I'm asking, didn't think it mattered. Just a simple, has anyone made a bracket to run 2 sensors.... lol...
Yes it's for aviation, yes it's for backup, and yes the sensor has a 99.99% success rate. What about the wiring, what about the ECU components, resistors do fail, wiring does fail, crimps do fail, capacitors do fail, anything 'can' fail. I want a backup, end of story.
I'll be creating an ECU that's for specific for aviation purposes then the stock ECU/MS/etc.
There is no bracket currently out there. End of thread.
Here is the best "image" I can show you of this Sensor side by side in 'a' FD RX-7..
I repeat the FD RX-7 is the only Rotary (any Mazda) which uses two of the exact same Sensors as Renesis RX-8 which uses the one in a car.
Mazda OEM E-position Sensor p/n N3A1-18-221A.
I suggest you ask the guys over at rx7club.com about any bracket as they are not available/made as a genuine spare part from Mazda,
you are going to have to fabricate two straps and mount them to another plate to fix on engine timing cover from what I can see/remember.
For aviation use.
BTW: Can I suggest next time when you start a thread here, to be complete in OP (original post) on what you are exactly asking?, like for aviation purposes?
That way you will not get the replies which does not suit your needs...and prevent other members for going around in circles and irrelevance, and going off track, this is a car forum.
