Bren Tuning, Engine Modes and safety

I have just woke up to the problems (perceived problems ?) with the 2018 throttle response and the cure which seems to be getting the engine re-mapped so I would like to share the following with you, the photos are of John's bike, he only had it a month or so and having moved from a Honda Varadero, so he was all "New Fangled" with the gadgets.

1. In 2016 we went to Scotland and John ended up in a ditch, the bike was a write off, John was unhurt and got a GS as his next bike.
2. He lost control and had a slide, he even has a video of it.
3. I had just passed the puddles/mud 30 seconds ahead of him on a 2015 K16, due to the conditions of the road I had my bike in "Rain Mode".
4. When I looked at John's bike he had it set to "Dynamic Mode"

I never told him (and I don't think he is a member of this forum) but I think having the bike in "Dynamic Mode" contributed to the accident. He essentially switched off traction control, downgraded the ABS and put his throttle on "High Sensitivity".

I like the engine modes, when its raining or the road is poor, I use "Rain Mode".

I also know that there is a close relationship between the engine modes and the safety features of the bike (I know this because the manual tells me so).

I pass this tale on to those who are considering getting their bike "Tuned".

Poor John

Had 2014 gtl premium spring 17 - winter 2019 (rode 25k miles). Bought used Wing to try out (10k miles), Nah-too boring and slow. Like GTL better, bought another GTL. Ha.

I'm sorry about John, but can you explain how you're correlating Bren Tuning and this post?

Good points. Iím not pro/con on the Bren tune. My understanding is that the procedure is to replace the Ď17+ throttle response or fuel map with a copy from the Ď14 version. Iím not enlightened or educated enough to know the intricacies of the software, but I donít believe the safety features are altered. But I donít really know. So itís good food for thought. Iím glad your buddyís lay down wasnít worse.

The safety features are not altered with the bren tune. Had mine on the bike (B) since this winter and have gone about 2k with it on through all kinds of weather. The going into rain mode you can feel the bike react differently as far as throttle, brake etc. It also changes in all other modes appropriate.

You should work in marketing! "how do we turn lazy throttle response into a feature?"


I am kidding of course. Still, I think that is stretching it a bit to say a tune may cause an accident. (I have no dog in this fight, my 2014 is perfect)


I have noticed over the years that people seem resistant to actually using the modes on the bike as they ride. Not sure if you remember all those people who complained about the early bikes having a snatchy driveline, but always had the bike in Dynamic in town???


You may be right, your buddy SHOULD have been in rain mode, but whether he had a tune or not wouldn't change the decision of the rider on putting it into the most appropriate mode.

IMO fiddling with the engine modes, or, getting your bike tuned/re-mapped bearing in mind the (no doubt) complex algorithms associated with adjusting traction control etc. is something I would not do, since it may affect the safety features of the bike that are linked to the engine modes.

Others in this post have commented that getting the bike "Bren Tuned" has not affected different engine modes, perhaps that is the case, although, I do wonder how they can be so certain.

To put it another way, if tuning a 2018 bike makes it "More Dynamic" does it make it "More Dynamic" in all of the engine settings? (and perhaps less safe).

Again IMO, the accident John had was affected by the engine mode he was using at the time, essentially he was in "Least Safe Mode" of operation, on a road with low to pretty much no level of grip.

So, this post is, hopefully "food for thought" for those among us who feel they need their bike tuned.

No offense, but all you've done is speculate on something you clearly don't understand. You'd do well to speak with the folks at Bren or any other company that offers ECU flashing as they could educate you and you'd not have made these suggestions.

I've been reprogramming EFI bikes and cars for a decade. There is no added danger as you suggest.

One rider didn't hit the mud and didn't go down. The other one hit the mud and went down. What does that have to do with Bren tuning?
