I did the test just now. It's on centre stand. I forgot what gear it's in, but it's on 5%TP, 4.7K RPM, around 80km/h indicated speed.
Starting from 74 - 111 deg C, I can say that AFR is flickering around 13.6-13.8, constantly along the temp range.
Above 105 deg C, I reckon that 13.5 and 13.6 showed up in a blink or two, but I think we can omit it.
Though the theory that ECU dumps more fuel at high temp is not proven at this test, we should remember that it is done only at 5%TP. I think it's not conclusive enough.
