The IMSA Pilot Challenge Series runs on Sunday nights in the 7:30pm time slot following on the Iracing schedule. Although it was originally intended to run with the official Iracing series, due to the large number of drivers participating online, the ECR drivers were virtually never going to run with each other in the same race due to the varying iratings that each driver has. It was decided instead to run a private hosted series filling up the field with the new artificial intelligence drivers which have been vastly improved from other titles. 

​

Drivers can choose from four GT4 cars which include the Aston Martin Vantage, BMW M4, McLaren 570S and Porsche 718 Cayman.
