EPAS Swap

I have an 07 Mustang track car that i did an EPAS swap with https://racecarservices.com/ harness that hardwire-taps into the canbus at the back of the OBD2 port.

I was wondering if anyone has been able to get into any of the EPAS system do any software update or tweeking?

Yes, but there is nothing to tweak when retrofitted. I suspect the different settings for the steering are in the cluster of a stock epas mustang. The only tweak for racing is buying the Ford racing EPAS. The one that isn't street legal and has no warranty. lol

Forscan can access the EPAS and allows you to edit the "asbuilt" data. I have tried ALL settings the rack would accept, with no discernable difference in driving feel. Even at track speeds (HPDE)
