Difference between SIMR-F1 and SLI-F1?

[Plebyxail]

Title says it all, I am thinking about modding my Thrustmaster F1 Wheel, and the two main candidates I see are SLI-F1 from Leo Bodnar and SIMR-F1 from SimDisplay. I was wondering what is the major difference between these two? Thank you.

Hi
I have the same project as you, the major difference is that simdisplay is no longer available.
