Any EPAS fans out there?

I will be sending info to my steering ecu for adjustable assist, but it needs to be can bus; engine rpm and vehicle speed. I believe that will require an arduino between the steering and Megasquirt but I’m still learning. The non-abs ‘07 Yaris steering controller plugs into most the Toyota racks and is said to utilize a simple vss/pwm speed input.

There are a couple of people who have tried running up to 9° positive caster in an attempt to correct the RTC issue without success. There is also a steering center reset process which I’ve read helps, but still doesn’t fix the problem.

I would personally get email confirmation that those aftermarket kits do not suffer from this issue before spending $1700+.
