BrenTuning Flash Development (Tech Talk)

FlatlineEF9 said:

I missed a lot on my vacation.

I was truly disappointed...but i wasn't expecting the moon from bren tuning. I know they promised a lot in their ads but being in Hawaii, with the humidity and heat...i was expecting lower numbers...just not that low. Yes i got a 5hp gain. Same dyno. same dealer. same tire pressures. Only difference was Bren, full akra, and the expensive sprint filter.

Jaret Campisi had the same setup as me, except with the akra instead of the bren tuning and made just a hair under 200whp in the heat of east coast summer. We started at about the same baseline. The vids of Akra flash vs bren flash back to back with the gains shown, i had hopes of barely cracking that 200whp number.

I'm working with bren to see if there is more they can do.

They requested the before and after dyno graphs so they can make adjustments to the flash. I have to go back to the dealer and get those and ill see where it goes. I also have the option of running 100 octane. So might do another run with that to see what happens. I probably should wait till the ambient temp in the dyno room is less than 94F.

I am hopeful that my solution may be some additional tuning of the flash.

94F but you're at sea level too so don't expect to find much more joy. Bren can't look at dyno numbers (unless you have A/F numbers) and magically make more hp unless they sent you bad data from the beginning. Bren makes wild claims but they aren't reproduceable in the real world.

I will. I have to get a second printout from the dealer because the first baseline runs were in 4th gear.

The second runs, after exhaust, bren, and filter were in 4th but he mentioned i might get more power in 5th. Got like 1.1 more hp. So the printout he gave me was the baseline in 4th and the modded 5th gear. Not a good comparison.

i saw the two graphs with the 4th gear runs and the operator said it was a consistent 5hpish across the band.

Can we just get a simple before and after dyno graph?

That's really the only thing that's going to convince me to spend any money.

This must have been done at some point if they are claiming any benefit. If you can't compare the final product to the stock mapping how can you possibly claim it's better?

If you can have them send the graph from both the same gears it would help. It's concerning that they picked different gears for before and after. Very odd.

I'd like to see you do a dyno run on bren, then a dyno run on akra and post the difference. Same day of course.


I have not seen bren post from their dyno stock exhaust stock tune then same day the graph for stock exhaust bren tune.

Another option is a drag race with the above bikes, do a few runs, swap bikes, do a few runs, take the average and compare.

I know that an independent one is coming, but why is this comparison not the first thing you see on their website?

Last, why is this flash 1300 dollars, is there something more better than a cob tune for a subaru or a panigale 1199, etc? How do canned tunes cost different, is it the Ducati tax basically?

I couldn't get the AKRA tune unfortunately. I bought my exhaust brand new in box but my dealer is stupid and didn't know how to link the exhaust code to my vin. They gave me the ducati service bulletin and it basically states that i have to make my bike into a track bike and trailer it to and from the dealer to get the AKRA upmap installed. When looking at bren, i figured, more power and i don't have to deal with all that towing back and forth.



My dyno pulls were done bone stock, and then a few weeks later with bren, akra and sprint added. 5hp gain.

so.. friday was the dyno shoot out... any word on when the 'results' will be posted? I see you are riding around the new V4R as well, any idea when a tune will be made for that?

I am sure we all want some real world data, with seeing real world dyno charts (not just a new graph made, actual dyno runs with knowing what has happened).

We have one customer on here stating a 5hp gain for $1300... bang for buck isnt there, so lets see what this past friday shows

Working on V4R which took a crap on friday (clutch master). Scheduling again for this week as they really want the V4R on the dyno. I can show the message thread with them if there are doubters here.

5hp is just peak gain and dyon'd in different gears. There are many other advantages you're choosing to overlook.

lamb00j said:

so wait, you had all the other bikes on schedule and you held off the much anticipated dynoing for a bike that the clutch master went out that wasnt in the dynoing anyway?

we really just wanted to see before and after and you spoke it up that it was happening friday, we dont care what bike it is with, just a stock to brentuning is all we care to see...

oh well, maybe next time.

Sharing my customer experience first contact with bren.

Bought a used brentuning device from a trusted forum member , programmer needed to be sent back somehow jammed in programming sequence with my 1199.

Bren told me 295us to fix issue , they have had it in their possession for 6 days I sent them 2 emails and one phone call hopes with update.

Do you think they returned an email or phone call even tho I am a new potential customer ? They were quick to charge me 295 while I was on phone with them.

I sold my rapid bike due to all the reviews about their tune what .... customer service.

I prefer dealing with a company which treats all customer equal irrelevant to how much they spend.

If the programmer is F?!#$D, No problem
, show me some respect with an email or call I will move on or buy a new device.

Rant over!

How did they find out who you are? Are they a member of the site but just lurk in the background? Very odd

Hopefully they just refund you since you are not happy and they produced no product for you. They will prolly sell this unit to someone else and double dip lol
