Take it for what it is. Ran my bike on the dyne today with Full termis and flash and it made 15hp more than with the full akra and brentune. It also fixed the dip at 7 with a straight curve all the way.
 
Can you please share your Dyno graph with us?

"flash" meaning the termi upmap?

how much does the full termi system weigh?

+1 can we see the graph? Also @miker1 where did you get info on numbers for brentune with full akra to compare to? The tune just went up this week, seems like a short period of time for you to install a full akra, get and flash bren's tune, dyno it, then install full termi, flash and dyno that. Not being a ...., just confused.
 
ElderBobo,



I just ordered my Brent Tuning Stage one kit for my 2020 V4s. I'm hoping to have similar results as you.

Yeah they ran my bike stock, with termi, with akra, and theirs. So im sure all that info will be up in no time. Cost me nothing since it was a mutual benefit.

I had a full Akra and brentune on my own bike and changed over to Termi and upmap on my own bike the same bike. Please don't call me a liar. Thats why I actually did not want to even post this stuff its not for you to verify I have actually spend a lot of money to do this and don't really need you to call me a liar. Like I said in my original post take it for what it is. I don't sell or market any of the products I used. I couldn't believe it myself I have been using Akras on all my bike since 96 and they have always been the best but not this time.

Not calling a liar at all, just was very confused. At how could all transpire in a super short window. How did you have brentune on your bike? Thats whats confusing me the most. Not calling a liar. Just the handheld has been for sale for a week nvm being able to send the info and your ecu image and getting it back. Just trying to learn like the rest of us, like i said before. I hope everyone gets the best combo no matter what it is from whoever, this is all about information, data, trials and tribulation.
 
miker1,


The feel/gain on your motorcycle is due to the Termi Exhaust? The reason that I ask is cause I've read that the Termi Exhaust makes more power than the Akra exhaust.

Would anyone really be surprised if the Termignoni system made more power than the Akrapovic?

No V4 MotoGP bike has an exhaust system like the Akrapovic. They are all styled like the Termignoni. Presumably, there's a reason for that?

I bought the Brentune when they came out end of last year I can look at my emails to Brentune if you want. I fitted a full akra to the bike the day I purchased it and I ran it with a termi upmap. When Brentune developed their system I purchased a Brentune module. The bike ran better with the Brentune and it was definitely better at the flatspot at 7. I ran it on the Dyne with the brentune and the airfoils came back wring the bike was very rich ontop. I contacted Brentune and send them the information that they requested but they basically wanted me to pit the bike back to stock to compare to what I had. I got a good deal on a full termi system. I fitted the Full termi and upmap since earlier this year and finally ran it on the dyno last weekend.
I don't understand when you say "how did I have a brentune on my bike" Brentune has been available for quite a while now. I can send you my emails to brentune if you want?

No need to get defensive, this is about the 2020 v4... not previous years so that is all good and dandy but like i said previously its completely different than the 18-19 hence why they didnt have a handheld or anything available for the 2020 until now after using my bike to figure it out so thats why it didnt line up timewise and thats why i asked and was confused..
 
I ordered my Brentune in April 2019 and received and fitted it in April 2019. Please take a moment and look it up. They posted a bike that they did on You tube in March I think last year and I ordered mine on the back of that. doesn't mean if you didn't know it that it never happened. Not defensive at all. Thats maybe why I don't post stuff on forums anymore because there are always the BS and non believers.
