RPM pickup vs hub speed


Just wondering around before ordering yourdyno .

My current setup that im building is hubdyno big Telmas and planning to buy everything from yourdyno 

The question is if im using the rpm inputs for the hubs how can i use the rpm pickup signal from spark plug wire to use it as main rpm command for the dyno or at least monitor the converter slippage percentage . i am talking about cars with no can bus or obd2 .

Can somebody recommend a setup or a solution

Hello and welcome.

There are a number of ways to get the Engine RPM. See here:

I use both rpm sensors of each hub for everything, any problem for +2 years.

i mean if you want to do steady state with high stall converter and you want the yourdyno to use engine rpm pickup to hold the hubs , you have no additional digital inputs , is there a way to add external rpm signal to usb and use plugin
