So, you're using the wrong ECU, and you wonder why you can't get it to pass? Lol.
The person not being able to drive it probably doesn't help you get reproducible results, but with the proper ECU it should pass.
Given that it's shifted at the correct time, and when the clutch is disengaged it doesn't shoot up to 7000342314234123 RPM. If it becomes apparent that they are doing damage to your car by their inability to drive it on the RR, then ask them to find someone who can perform the test with a manual transmission.
Your problem isn't the man or woman or chimpanzee driving your car on the RR, it's the ECU not being correct.
