I've ordered a MAP Sensor. It's en route...
So you added 5% to the entire torque map?

I increased the whole torque map above 5000 rpm. Funny these guys buy a tune developed on some random bike with an entirely different set of sensors and they think they're getting a good tune for their bike. Ridiculous.

Some are knowledgeable, some make stuff up.

The fuel maps have 600 points. The typical "tune" is a corrected dyno pull on someone else's bike. So WFO is corrected to that bike. The rest of the map is pretty much ignored maybe some correction to ensure idle quality. And extra fuel added back at the top so you don't melt a piston on a bike at the far end of the sensor tolerance stack. I do the complete map on my own bike. Takes time to do this. Typically transforms the throttle response. I'm new to all these electronic nannies but I'm closing on full Grok (was that from 'Stranger in a strange law' or 'Brave New World'?). ME/ChemE with a PE (no not the gym teacher type the kind who signs off on stuff). And lots and lots of engine building and tuning experience. Stop yourself.

By your own admission you have bring a diagnostic computer on your rides. Stop fooling yourself.

And I also carry one in my car and my truck. I ride my bike thousands of miles at a time and thousands of miles from home. Lots of electronic stuff on these bikes to go wrong. I also carry tools, tire pump, tire plugs, chain lube etc. Stop yourself.

Awesome info as usual.

Got time to replace the Cyl.4 MAP Sensor and the bike started at first touch without any CEL. Running fine for now. However, Woolich Diagnostics still shows U0CCC which is CAN bus related. Looking for inputs from others who've used Woolich, if they've faced anything similar. I've hard+soft deleted pair, evap, 02 and exup by turning them off in woolich 2 years back. Machine has run flawlessly except for the Map sensor issue which is resolved.

On the other hand, my doubt lies in the after market led tail tidy. Led's have a lower resistance and this can cause the canbus to throw an error.

The U0CCC is a Woolich generated general comm code. Dump the faults in the other computers (BBS, ABS etc).
