So for the 3 people interested, I worked out that the function is implemented in TuneECU, and worked out the procedure by reading the service manual.

For anyone else with the same issue, TuneECU just triggers the crankshaft position adaption routine. I suspected it did as it let me run it, and if I cancelled it, the ECU disconnected me and I had to reconnect. I just didn't know the procedure, which needs the engine running (duh) and in my mind the thought of redlining the bike in neutral didn't sit well with me. However, from the service manual:

4. Hold the throttle fully open within 60 seconds of being prompted by the diagnostic tool. Do not close the throttle until instructed to do so by the diagnostic tool.

Note
• Upon holding the throttle open, the engine speed will increase and decrease in cycles at approximately one cycle per second. The cycles are repeated until the crankshaft position adaption is complete.
• Adaption is typically completed after the fourth cycle.
• You will be prompted to close the throttle when adaption has completed.
• The diagnostic tool will allow the test to operate with the throttle held open for a maximum of 10 seconds (approximately 10 cycles). If adaption is not completed in this time, the test will stop and you will be prompted to close the throttle and turn the ignition OFF. Note any on-screen messages and investigate the cause before attempting to restart the test.

5. Close the throttle when prompted by the diagnostic tool.

So I did it and yes, it revved up and down 4 times and stopped, and then Tune ECU told me to let go of the throttle and turn off the ignition for at least 120 seconds. On restart, code was cleared. Huzzah!

Hi, I've connected to TuneECU gone to adjustment section and there isn't a crankshaft position sensor adaptation option, any ideas?

Just wondering are you using Sagem or Keihn as the EFI type?

So I have a Samsung tablet updated with the latest Android and patches available, an OBDLink MX+ with the latest firmware, the most recent TuneECU version (updated it a couple of days ago) and the option is there for me. Have you made sure if you’re using a phone with less screen real estate that it’s not just off the screen and you have to scroll down? Otherwise as other folk said in the other thread, reach out to TomTom or Alain. They are both fairly responsive.

FYI this was just going down to the bike and turning on the ignition (one click up, one click down) and without starting or warming the engine… Just to clarify further, make sure you scroll to the “dashboard” page rather than the map page, click into ECU, then Tests&Adjustments, then Adjustments.

Hi again, have you seen the thread messages from Nashvegas? What are your thoughts? I'm going to try his suggestion a little later. Question, forgive for asking, how long do you think it would take to incorporate "Crankshaft Position Adaption" on the Adjustments screen / page for 31024? I'm not sure of the process involved in achieving that goal quickly.

Yes I have a 3R (that’s my video everyone keeps posting), and yes I saw the other posts - Nash’s suggestion is worth a try. FWIW, I don’t imagine it will take Alain long to add if it’s an oversight just on the TFC. But if Nash’s suggestion doesn’t work, you’re stuck either waiting for Alain, or biting the bullet and getting a dealer to do it. I have no clue why your local dealer insists they won’t do it, I’d have thought charging you a hundred quid for 5 minutes work they wouldn’t give a **** what tune was in it. *shrugs*
