Put the 31018 from Master Penner on a EU R.
Used TuneECU with a compliant bluetooth/ODB 2 adapter (MX+), as per their instructions in manual - first time I uploaded a map on a bike.
It failed first, very scary as the bike is kind of a very expensive LCD screen only after failure... but then TuneECU suggested automatic ECU recoverr, which ended up working, and I could start again with uploading Penner's map. Upload took something between 15 and 20min.
It seems the failure was because of voltage drop: I've got very confused with the headlight fuse removal requirement, because some EU bikes like mine have daylight always on, there's nothing you can do about it... Removing the headlight fuse did not do sh*t to daylight, so at first I figured I had to put my front lights from daylight to regular light position to benefit form fuse removal. Don't do that: remove the fuse as advised, and let the daylight be, it's OK. Otherwise upload will probably fail just like it did with me. Battery charger seems to be a must as well, because battery voltage dropped from 12,9 to 12,5V during upload process, even with a small 1,5A 12V battery maintainer, so I think it's mandatory to succeed.
Once map is uploaded, turn bike OFF for 5s, turn back it ON, as requested by TuneECU (apparently required for the ECU data to be stored).
Then I would not advise to reset adaptions with TuneECU available software ECU resets, as it is sometimes advised: it seems this may cause some non-automatic adaptions to be reset as well, would set error codes on, and require your bike to go see a Triumph garage.
To reset adaption, as per workshop manual, and only when the engine is fully cold: turn the engine ON without touching the throttle at all, let it run idle until the radiator cooling fans turn ON (you can see them easily from behind the radiator, wait till they spin), then wait with the bike still running at idle for 12 minutes more. Done.
I did not have to reset/restart speed regulator.
All that rookie lessons learned passed: Penner's map feels awesome. Smoother, less deceleration pops - maybe a bit less engine brake as well; punchier at low revs, and seems to push stronger further than the factory map. Thanks a lot to you Master Penner.
