I' ve been busy with the Dyno last week and made a hole in the floor and gave the Dyno some grease and a fresh paint job. I 'm very enthusiastic about your product. But I have a few questions.

* The loadcell on the MAHA Dyno is not a S type but more a "block". I attached a picture of it. What would be the distance of the measuring point relative to the centre of the brake. Or do I have to change it to a S type. But if so where is the best point to instal it. 

* Is it possible to put a company logo in JPG, PDF or other format in the print of the dynograph? 

* I am looking for a nice solution to strap down a car as easy and fast as possible and is even with the floor so you don't brake your neck on it when you walk around the dyno if there is no car on it. 

* I don't really understand how the load of the cpu of the PC gets more when you have more runs on the screen. I found some information about that on the website but don't understand that. 😊 

* What is the average size of the file from one run? 

That Semikron device is the controlled rectifier. You can try to follow the 2 control signals (the white wires I think) to see where they go. But there does not seem to be a nice small stand-alone power controller there... you get a lot of other "stuff" with it. Probably you could reuse the bridge and buy a controller like the Semikron SKPC 200, I believe it can control that bridge (check the specs). 

Picture of the main board

Thank you for your input. I saw on the powersupply of the brake that there is a SEMIKRON SKB33/08. than it has two wires to the main board. And there ar 2 smal transformators of 18 volts. If someone knows where I can find the wirediagram I think I maybe can find the 5 or 10 volt analog input signal. But the problem is the whole system works on one singel board and there is for example also the low voltage FAN switch from the remote. Also i see some electronics for the analog needles (gauges) on the front of the machine. I will try to make some pictures of it. 

Welcome to the forum!

The Telma CC160 can hold 1600 Nm, so for example at 3000 RPM that is 670HP. However the max torque is not constant over the RPM range and the torque capacity falls when it gets hot, so it will be less in practice for at least for long steady state runs. For power runs (sweep the RPM) you have the effect of the Moment of Inertia that helps absorb HP, so that will give higher HP capacity than steady state. So the capacity should be much more than 250HP. I expect it can do 500hp without problems in a power run. Anyone who has a Maha LPS13 can chip in?

For the power supply, they are all roughly the same design but differently made for the different dynos, I don't know this one in particular. But if it works you can try to find an analog signal, typically 0-5V (sometimes 0-10V) that goes to the thyristor/rectifier controller board. 

Otherwise SportDevices is an easier path, it works great. Let me know if you are on a budget, there are lower cost alternatives if you are a bit adventurous. 

Yes, you need a new RPM sensor. The Maha uses an VR sensor which is not compatible with YourDyno. You also need a new trigger wheel, check the wiki on that. 

Good luck!
