I had to take a break after multiple attempts to access bikes info to download. I think I'll try again this weekend. BTW I was in on the initial discount offer and still unable to get it done. May have to get my daughter to come over and help me out!😭
Whoa, hold the phones!:oops: Are you having difficulty getting the handcontroller to read the bike's current ECM configuration?

The laptop interphase can be a bit clunky. I seem to remember having to shut down and restart once or twice.
 
Finally recieved the Brentuner (1 week from US to Australia, which is pretty good) - mine is the bagger version and the port is behind the left hand side cover in its own home-socket, so pretty easy to find.
Reading the bikes ECU & sending back to BT Moto was pretty straightforward following the feeding back from yourself & Cheshire - thanks guys !
Questionaire returned, now the wait for a return flash file - any idea how long it normally takes them to do it ? So looking forward to this.
I just did mine on Tuesday and they sent the map back in two hours.

Got the mod file this morning - flashing process went pretty smoothly ~ 5 min upload, another 5 min of switching thebike on / off, then done.
No crashes for me luckily, using an old Samsung Windows 10 Pro tablet, worked well.
Started the bike and it immediately settled down into a smooth 1000rpm idle, blipping the throttle I could easily tell it was more responsive.
Went for a 1 hour ride & boy, this things come alive !
Having the muffler plugs drilled out, DNA Stage 2 filter & frame (all the plastic cover & snorkles removed) + the Brentune matched to these mods makes the bike so much more enjoyable to ride - can feel a bit more power and roll-on torque right through the rev range, engine feels smoother too (less of that harsh vibes around 2500 - 3000 rpm) and certainly revs quicker.
Where I feel a big difference is in 'rideability', by that I mean the finer & more connected throttle-to-engine response - that slight fluffiness / pause on throttle movement has gone - so that throttle modulation & bike balance are better and for me provides more confidence.
BT-Moto have definitely delivered improvements exactly as they stated in their web info - great job and worth the price of entry (ps, by the way, they are still honoring the R18Forum bulk buy discount - put the code in and it worked).
Great & responsive company and big thanks to R18C and those involved in supporting this forum, taking the plunge to test out the product & telling us about this tuning mod - is good stuff !BM R18b JD.webp

I have been in contact with BT Moto Sales and specifically asked about the R18forum discount... the sales guy, one Niel responded that "that group buy was ended a while ago"
So I went ahead and ordered it anyway, delivery will be sometime next week. Obviously without the discount.

Now you mention that you did get a discount...what amount would that be then?

feeling a bit pisssed (to put it mildly)

They do offer a military discount I believe. Covers veterans also.

The package from BT arrived today, without any hassle from customs, VAT tax office or handlers charging extra money for the import...
For me the discount question is solved; it only damages the fun to be had....

So, I'll do what I am told to on the box "unpack and play"

keep you updated

Brentune YouTube & a couple of clips on here may prove helpful
 
Finished install just now, but don;t dare start her up already... the neighbors already hate my late hour hobby... it's 2:00 in the morning.
More fun in a few hours.

This was a really rapid project... uploaded the original map (with questionaire) at 13:00 today, recieved the modded map before midnight and finished install at 1:30...
I am still and again amazed over the functionality of the Internet

a small update:
this is what I sent to the good people at BT-Moto.... some very strange and un-expected coincedence during the flash...

Hi,
a bit of feedback on the flash...

oops... how many coincidences can one handle/ Murphy has left the building...

Last night I did get your modded file and after some reading and thinking (and a stiff drink) I decided to go ahead and load it after midnight.
Could not start the bike to see if everything was succesfull; that had to wait till after sunrise

In the morning, at about 10:00, I powered up the beast and started her up.
I was very soon surprised by some very nasty service messages on the display that would not go away and could not be cancelled out.
OMG I f..ked up the ECU!! that was the first thought...

I did read up and started preparing the downgrade, back to the original map...
But then I got the bright idea to check the odb2 status, with an app (MotoScan) on my phone and an ODB2 bluetooth plug, normally used in my car.

Did find that all the hassle on-board was caused by the service interval timer (date based) that was set to expire today at 00:00 ... that same day and roughly the same time that I did the flash.
Managed to reset this service related issue; took out the date notification, but left the km notification intact.
nb BMW will not be happy with this type of actions... this could cause future warranty issues... I couldn't care less.

And from there on everything just worked fine.
Went out for a 100km+ test drive and yes, it functions just great and I am very happy with the results.

How much luck can one have... bought a lottery ticket, just to celebrate...

That was a stroke of luck that you were able to fix. Would you recommend the Bluetooth analytics pack you bought?
 
I finally got the first service performed at the local dealership. I did the Bren Tune and found the entire process very simple and trouble free. In fact I I got the new map back from BT Moto in less than an hour.
My impressions are that it smooths out the idle quite a bit (raised the idle 50-100 rpm and In think that has a lot to do with it). It now accelerates smoother above 3,000 rpm and feels slightly quicker. The upfront cost of the tuner is steep for the ROI but I am the type that modifies and perfects a bike to my riding style and once it's done I move on to another project. My previous experience with digital tuners were with Dyno Jet tuners on the Thunderstroke Indians and my FTR. The cost on the flash tool for those bikes is about half and the ability to modify and fine tune the map is a huge advantage over the Bren Tune tool. In the end it is up to the individual rider to determine the value. My bike is a base model being converted over to a bobber using LMC parts, so I already know these bikes are not a cheap date to play around with. That being said I do a lot of cross country riding on my Roadmaster and I went full Stage 3 to perfect that bike for what I use it for. If I had one of the touring R18 models and rode it like I ride my Roadmaster I would wholeheartedly recommend the Bren Tune.

Now if my LMC fender and other items would arrive I might actually get a few rides in this riding season on the completed R18 project.

I don't have the good OBD2 bluetooth connector yet, the one I have now is a cheap ali version that does not support long Canbus messages, but this app is not only analytic but you can also set/reset stuff.... a BMW mechanic advised it and he uses it on all his bikes.... I hope to get that OBD2 connector shortly; it's on backorder... and then I can tell more
 
I’ve installed the Bren tune with the dna filter upgrade. I left out the snorkles, and installed the dna top filter housing. Money is subjective but for 900 bucks (brentune,dna stage 2), to me it’s most definitely worth it. The guys at brentune are awesome as well. Firm handshakes to them.

did get the UniCarScan UCSI-2100 last week, before I went on vacation to the UK... did take it along, ofcourse, and tested it while driving there, of course, Works just fine in combination with the app, can send long can bus messages, so resetting things like service interval, or clearing alarms, is no problem...
 
BMW engineers went to a whole lot of trouble to create that fake lumpy idle in the Rock mode and to give the genuine boxer 'feel' in the ride only for you guys to celebrate tuning it out. Well I'll be...

My perception too. I lóve the old skool lumpy idle and the boxer feel engine.

Have the exhaust flap servos deleted and the intake freed up with a dry Sprint filter, no cover, no snorkels and honey comb side plates.
Result more lumpy and boxer still. The response to a handful of throttle is near scary now :ROFLMAO:

The bonus of the bigger rough bangs is that they are audible too. The fishtailed teardrops rare loud enough now.
