You don't have to if it's a PDK; will still read fine just get speed sensor errors if the front wheels aren't moving.
I did mine on mustang and it read accurate readings, even though I had a christmas tree afterwards. Cleared with scanner and all was well.
Good to hear @atish I had a bunch of lights also but a quick 5 min drive around the block to get the wheels moving again and they all self cleared after a restart.
Nabil: You are going to have to do multiple runs, especially from race launch, to see if the 3-4 shift persists. I have flashed new tunes and for the first few runs the car shifts beautifully. Its only after the car and ECU adapts to the higher power does it then restrict the torque. If you can get 5 or 6 pulls with no flutter then you can say it was resolved. AND you will need to compare your previous runs agains the new tune runs to make sure the solution wasnt dialing back the power. The goal is "full" power and boost without the flutter..
Our protune file. So far the car is running hard. I think we can get the car to a 7.2 60-130. As far as parts go I think Nabil will have to chime in but I believe just exhaust and tune.

Low 7's is still madly fast for what it is! Good stuff
Yesterday I loaded another tune-file from my COBB pro tuners. Did a WOT run to 7.5K from 2nd, 3rd, 4th gear recording on the AP. This time it was perfect. No flutter or throttle pull back at all.
Looking at the logs after the runs, to my surprise I noticed that there was a pull back on the "Throttle Angle" as before but this time it was much smoother and slower reacting. So what has been happening is my "Engine Torque Actual" was getting too close to the "Engine Torque Limitation" real fast, within 20 ft. lbs. or less and that caused the "Throttle Angle" to pull back fast, too fast. Now when this same WOT runs the "Throttle Angle" is pulling back slower and so the "Engine Torque Actual" is adjusting sooner and keeping the distance from "Engine Torque Limitation" a little more than 20 ft. lbs. The logs show around 620 ft. lbs as the torque limitation and I was hitting 605 ft. lbs. on some runs. I will keep testing and maybe some fine adjustments from time to time.
Just curious if you have any updates on the refinements to your tune

So far the last tune file I loaded has been great. No pull backs as far as I can feel. I will do some more data log runs ( like 6 in a row ) and see if the ECU learning changes anything.
