I am in the process of building a new buggy. While at a buggy show in Lansing Michigan a few weeks ago I stumbled across a power steering unit out of a 2008 Nissan Versa. The unit is made by Koyo and appears to be complete. I had planned on running hydraulic power steering but thought this may be a nice alternative.
Now for the problem, the wires to the eps control unit and the torque sensor are cut and I have no idea how to wire them up. I stopped by the Nissan dealer and they provided me with a wire diagram but I still do not know where the four wires coming off of the torque sensor go to. I was also able to find and download a full service manual online. I have spent 20 plus hours looking online and can not find much. I have also posted on several forums and I am making a little progress. I also sent an email to Koyo and I think I heard them laughing at me when the responded with, "We only talk to car companies” I have also sent an email to the folks over at Unisteer and have not heard back. The unit I have is very similar to the Ididit steering column. http://www.unisteer.com/mm5/merchant.mv ... e=UNISTEER
Through the help of another posting I made some one suggested I speak with this guy (russellpalmer47).

He said he does not work on the Koyo systems but said he has been setting up EPS units for a while now and has shipped several from the UK to the US. I am waiting for more information.
Now the reason fo rthis post. Does anyone have anyinformation that may help me with this?
Thanks,
Bryan

I believe that the Electric power steering systems require you to run the ECM otherwise they will not function. There may be a way to defeat some of it however I do not know how..

Retraction/update: I should have looked at the links before I posted lol. I did not realize they had allready found a way DUH!

I have two of these units and getting info for the lan connections now. It appears that guy on ebay is useing somkind of reostst to co ntrol them. He wont release any info on it so mabey if somone buys one we can reverse engineer it to see how it works.

I am thinking the same thing as you are Subysteve. The last one he sold wasn’t too bad of price even shipped from the UK. I am still waiting to hear from Unisteer to see if they can help.
What manufacture of eps do you have?

Firebug, if you liked what you saw there wait a few months and I am sure you will appreciate what I am building now. Watch the new build to see how the project is coming.
