V85TT ecu remapping
JStorm:
A follow up after a few weeks with the Beetlemap on my 2020 V85tt.
To start, I had a CEL for each Lambda sensor being not present. Odd since they should be disabled. Emailed Mark to clarify this and was told it's not right. I'm the first to report the issue and he would look into it. Ok cool, thanks! I have since welded sensor bungs onto the headers and reinstalled them. Reset the ECU to get rid of the CEL and have just been riding that way. I'd like to remove them if they are disabled and plug the openings. Maybe monitor with a pair of wideband O2s for my own entertainment and ever-curious pursuit of knowledge.
Cold starts are rougher than the stock map was. Takes a minute or so of hunting up and down before setlling into a smooth idle. Normal riding shows a flat feeling off-idle or after gear changes, surges to a stronger acceleration until I roll out of the throttle or level off into a steady cruising rate. Not really problematic but it doesn't seem like an improvement over what it was. The decat exhaust came with all new header pipes which are not double wall like the stock setup. I can see a difference in bluing of the pipes indicating they are probably not running very even, from a fuelling standpoint. I can still see the lambda values in guzzidiag but have not tried logging while riding. I find it odd to see the values if they've been "disabled" in the map. I have not discussed this with Mark yet. I have yet to look side by side at the maps in tunerpro, though I have looked at them both. (Have to sort out the "compare bin files" function. I would like to compare them and look for differences.
In summary, my bike runs after the reflash. I didn't brick the ecu. Once warmed up it seems to run ok. The new map is certainly not "transformative" as others have reported. I will continue to communicate with Mark to see if maybe I need a revision or something.
I would add pics of the guzzigiag showing the codes and the exhaust for sensor placement and bluing comparison. Imgbb is not playing nice tonight.
Thanks for reading,
Jay Storm

Now finally also E5 with Lambda=off
The DÄS modified MASS-Moto exhaust system is not cheap but very effective.
Roland Däs is a perfectionist, always looking for the optimal technical solution - no marketing blah blah blah

I have begun going down this path and can confirm that Roland has been excellent to deal with, despite a 20,000km distance separation.

Yup! And thanks again Steve, still running like a Freight Train!

I own a 2020 V85TT
I would like to get a lot more power , but specially torque out of the bike.

You're gonna need a bigger bike...

Power you want? Better get a BigBlock!!!!!! No substitute unless you go water cooled BB.
