Hi i am new but what i need is help on wiring the eddy brake control it has 3 wires i-con , i-sig & i-pow i would add a pic but see no way to do that
hi just need a bit of help i have a old Mustang emission dyno and the power supply works with a 0-5v signal and there are 3 wires going to the board I-Con , I-Sig & I-Pow how is this wred do i just need 2 wires or use all 3

What you could try is to connect a 0-5v adjustable power supply to icon and isig and see if that controls the brake. Try this before connecting to YourDyno.
mark,
I am building a ASM97 currently as well!
My advice is be careful with that eddy power supply. I made a bonehead move trying to scope the load side waveform. My scope wasn't isolated from ground and I let the smoke out of that card. I found a burnt trace on the pcb and repaired that but now all it does is produce full power, I cant modulate it with a 0-5v or 0-10v.
I am excited to see your build. I am currently re-gearing mine to slow the flywheel and eddy down so I can spin the rollers at a much faster speed than the rated "60 mph"
I finally talked talked to a guy on DIY Dyno on facebook and me told me how to wire it up on analog out the ground wire goes to 0V and the signal goes to out B but i have not wired it yet but will in the next few days when i get some free time at the shop .
Yes, analog out is OutB and 0V. Remember to swap the jumpers inside to the analog position. See https://yourdyno.com/YourDynoHelp/brake-control-basics/
Ok the brake is working now i just need to wire the roller rpm and load sensors it is really simple once you find the info you need
has anyone used this for engine rpm MSD Ignition 8918 Tach Signal GMR Pickup this is the inf on it
Tachometer Signal Pickup
Tach Signal GMR Pickup
Tach Signal GMR Pickup; Converts Low-Voltage/High-Current Pulse To A Clean 12-Volt Square Wave; No Splicing Required;
- WARNING CA Proposition 65: Yes
- WARNING CA Proposition 65 Message: WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov
- Clip to a coil pack primary lead to for a stable 12V square wave
- For a tach; shift light or RPM-activated accessory
- Connect to a diesel injector wire for an easy tach installation
- Operates w/5-24 Volt Input For Universal Applications
Just think of the things you can easily accomplish with our GMR pickup! This little device simply attaches, with no splicing or cutting, to a current carrying wire and turns that information into a 12 Volt RPM signal. This signal can be used to activate a shift light, RPM activation switch or a tachometer. One example is to connect the GMR, which stands for giant Electro-Magnetic, to a diesel injector current wire. This will produce a signal that can be used to trigger a tachometer or shift light! Another example is on late-model engine equipped with a coil-on-plug ignition system. One of the coil's primary current wires is simply routed into the pickup clip and GMR converts this pulsing into a 12 Volt signal for a shift light!
Racers never stop experimenting as they search for every way to wring out more power or handling performance to to gain an edge over the competition. The team at MSD is no different as we strive to deliver the products you need to meet your performance goals. We continue to innovate and invent components and technology that deliver performance and reliability with products that are easy to use and install. Over the course of 40-plus years, MSD Performance has been driving the development of innovative components that helped shape the way our cars race and perform. From super speedways to road courses, land speed racing to top fuel dragsters, and of course your traditional hot rod, MSD has provided the components to fire nearly anything in motorsports. Early on, MSD focused squarely on ignition systems with revolutionary products like the multiple sparking CD ignition, timing and rev controls, billet aluminum distributors and the Pro-Mag, an incredible breakthrough in power and endurance. Today MSD is developing electronics for your entire powertrain. The Atomic EFI systems for the LS engine platform and throttle body are now complemented with a transmission controller. Our DynaForce Starters and Alternators ensure that your engine cranks over to fire up and the Alternators keep it charged. MSD is poised to deliver components that work and communicate together to provide performance and value.
Thanks for that tip. This MSD Ignition 8918 Tach Signal GMR Pickup looks good! I will order one for test.
It should be possible to connect directly to YourDyno's second RPM input. Note it MUST be powered by 5V, or it may damage the YourDyno board.
? while setting up the load cell i see Dyno/drivetrain Moment of inertia Hub / Roller is this the inertia weight as i have not been able to find what to set that at
anyone know how to make the warm up motor work i took a look at what i think are the wires that control it one said V+ the 2 others say forward and reverse so i am thinking it is a 0 to 5v one the V+ and depending on what other wire you use would make it go forward or reverse does that sound right
@mark, there is a video on the YourDyno youtube channel on how to determine the MOI.
The "warm up motor", what is that in reference to?
there is a electric motor on my dyno with a thin belt that goes to the rollers and could spin things up also my dyno has some airbags to lift part of it but i am not sure what they are for
The airbags are for lifting the bar in the middle between the rollers to get the car out. You need to control this separately with compressed air.
I don't know what that electric motor is. Normally there is no need to spin up the rollers, the car under test does that. Don't connect it to the YourDyno box. You can post a picture of it, maybe we know when we see it.
Did you have a chance to test the MSD 8918?
