I don't want to pollute his sale but.... OBD shows zero warmups since dtc's cleared. It was jusy cleared. He should show readiness but it would say it's not. Who knows why the dtc was cleared and what it is but with zero warmups, it likely comes back quick. Suspect as F though. FWIW, you can remove dtc's from factory ecu's. I had canister and trans dtc's removed.
Cool car but seems to lack a/c and considering the amount of work and weight I don't see why it doesn't have it.
