A few days ago i realised i wasnt multiplying the speed value to the EPS by 100 like i should have been :P
Fixed, and now it feels much better.
Still a more tweaking to do though.


So I'm guessing you got the CANBus controller to work? I might have to hit you up for the correct packets when I get around to making mine.

One thing I noticed is that the wakeup for the power is time based. If I turn on the ignition and sit there for a couple seconds, it will turn on without me inputting a torque. I am guessing it waits for an RPM signal after a certain time, and if it doesn't get it, it will automatically turn on in limp so you can move the car around if it is broke down/out of gas.

So is your blog up to date? Its still running in limp-home mode so far?
Megasquirt can't output CAN bus packets suitable to run the EPS without specific support being added to the MS firmware.

Its been a while since i update this thread... mine is all up and running & on the road.

Digging up bones here. I was curious if you had the photos and everything still for this project. I have an ST185 that I am going to try and convert to EPS. I would appreciate the help.
