Default SuperMiata dynoshaft

We're working with AEM to get the Dynoshaft hardware to work on a stock Miata drivetrain. Unlike many domestic RWD V8 platforms, it is far from PnP on a Miata. The sensor housing needs about 2.5" radial clearance around the trans yoke, which conflicts with the PPF by about .5". The housing is designed to clamp circumferentially to the extension housing so it interferes with the shift turret. We will cut off part of the sensor housing clamp and make a bracket off existing bosses on the extension housing. The tough part is hacking into the PPF and sorting out a welded on reinforcement for the U channel.

Will update as we make progress.

For those of you that don't already know what a dynoshaft is:
Dyno-Shaft On-Vehicle Dynamometer

In short, it's a torque sensor which calculates horsepower. As it is just a sensor with a digital outpit, it needs a D/A system to plug into. On can not just open up AEM tuner and start logging. It can output Racepak Vnet protocol and CAN also. Much potential with this device. Just a few of the ideas that come to mind:

Real time closed loop spark map tuning
Verification of output for racers limited in power output
On road A/B testing of engine upgrades
Aerodynamic drag measurement
Gearing optimization
Road surface grip measurement
Tire grip measurement

If we are able to get it up and running, it will be expensive. Probably in the $2500 range. Not enough market to serial produce these. The kits would essentially be hand built one at a time. We are not set up to do that, thus the expense. Current plan is to only make one production run of a few sets for certain customers and that would be it. We would have 2 here. One to rent to Club Orange customers (you know who you are) and loan to Team 949 Racing members, the other kept for use on our cars. In short, we're doing the R&D because we need one for our race cars so a few select folks will benefit from said R&D. If the tech changes and we can build these on the cheap, we'll jump at the chance. No idea what rental costs might be but the deposit will likely be $2500. NO ETA

Nice. I can't wait to see what you all come up with in terms of feedback/tuning routines.

$390retail for AEM's datalogger, or can be logged/displayed directly within the series 2 EMS.

Retail on the dynoshaft is ~$1500 for applications that exist. Another reason to do a T5 swap, too bad you roadrace guys don't like the T5 ratios.

Awesome tool. Playing with Data Acquisition and PLC controllers at work all day always makes me think about what can be used the automotive aftermarket. It's just too hard to make things like this that have such a small market affordable. Limited rentals seems like a great option. Curious to see the uses you find for this.

Oh, you know that I will since I would be using this to tune local cars instead of paying $$$ for dyno time.

Any concern that the new yoke moves the pivot point at least 1" further back on the driveshaft to fit the strain gauge? I don't have a miata with a stock drive shaft to check but I'm assuming at the stock length it doesn't have enough of the yoke exposed to fit the strain gauge.

Shorter, custom shaft
