Hello all,

I just installed an IS-F steering ecu on my little brother's IS350 this weekend. It came out of a crashed IS-F.
I didn't do any calibration because I've read that if you it came out of another car, you don't need to do the calibration. Calibration is only needed if you buy it brand new.

With that being said, after the install I definitely felt the steering get stiffer. But, there is a slight vibration when turning the wheel left and right when I'm sitting still.

Has anyone ever faced this issue before?
Is this because I haven't gotten it calibrated?

Any help would be great, Thank you in advance.
