All, this thread will house performance info on the 2021+ V85TT

From ~65 rwhp stock to 83.6 rwhp. Full kit has K&N with opened air box lid, SAS, full GTM exhaust system and UpMap base WITH PC6/AT-300 for dynamic GTM tuning.

Overlays on the same '22 V85TT E5 bike below show a completely Stock bike but with Upmap & GTM SAS (67 hp/50 lb.ft - yellow/blue-grey trace), second is with SAS, GTM Hdrs/Y with Stock muffler and opened air box lid with K&N, UpMap and custom mapped PC6/AT-300 (77 hp/59 lb.ft - orange/purple trace) and most power is the SAS, Full GTM Exhaust System w/long muffler and opened air box lid with K&N, UpMap & Custom mapped PC6/AT-300 (83.6/62.5 lb.ft - red/blue trace).
16.6 hp/12.5 lb.ft / ~25% gain for those not good with math. ;)
Enjoy.

Very good, we'll have that mapping sorted in the next week or so. We'll put purchase info online next week and link it here.
 
Thanks I'll get it overnighted to me because I'm taking a trip to death valley for a month of riding the whole Southwest you know I'm from New Hampshire thanks again Paul
 
Todd, are you planning to have separate maps depending on bike setup (i.e. stock vs aftermarket exhausts, cat, catless, etc), or will this device be smart enough to handle such things once a good base map is set?

Separate maps. This is still a static device that revises the base map. The algorithms take it from there. ;)
 
Just giving a quick update Ive only ridden a few hundred miles since the initial GTM tune was done but its been all urban miles multiple starts and stops and alot of traffic. the bike is cooler when sitting at lights and it starts better when hot than it did pre tune, as far as cold starts it got down to 40 last night and it started right up I rode it once before the tune in the 40s and it cranked several times before starting. I cannot give accurate MPG numbers simply because I'm still "enjoying the power" a bit too much but overall im pleased with the results.
 
@GTM® Good to see its available 👍
I'm curious how it works for an aftermarket exhaust setup that doesn't have a map explicitly built for it (lets say, hypothetically, something like a Mistral full/catless system w/ db-killers intact). I see that they do have a sort of "generic" aftermarket map available, and just wondering if its a "good enough" (smoother/cooler/better than stock map) solution, or if it really pays to have map customized for that particular setup?

They have a "full system" Zard without cat map available. I'll be testing it with some of my exhaust and can (hopefully) get my map(s) uploaded to their system for install.
 
Todd, I look forward to hearing how your tunes come along. Once you are happy, I'll snag one as well. Keep it up and as always, TY
 
The shop has been massaging the AFR and a gas analyser. Not sure but think Rexxer was used

Progress. Fitted and running. Getting one step closer to a full dynamic kit. I’ll post as we go.

Great! Will this work in tandem with Upmap, or will it replace it?

*IF* UpMap will cooperate, it would work in conjunction. The PC/AT dynamic system is worth every cent, however stock 02-sensor delete is mandatory. Also, the larger M18 sensors bungs are required. A problem for all of the E5 bikes using the smaller M12 sensors.
 
Wow. Three likes, and several smart-asses on social media. Nearly a 20 hp dyno-proven gain, and everyone just shrugs? If this had be me on the other end, I would've fallen off my chair in astonishment. Can't wait for Penis Rotor and his posse to sh!t on it. Heh. Oh well, onward.
