BrenTuning Moto Flash vs Woolich Racing Log Box B v3

[Warree]

Does anyone have comparative experience of which is best for Gen2?
The Woolich including a wideband 02 sensor but the Brentune can be quickly taken back to stock if the bike needs to go back to the dealer.

Haven't seen the direct comparison but the Woolich (not Woolwich or Woolrich  ) system is quite simply the same sort of package tuners use for ECU tuning (some actually use woolich specifically) so yes, you can just save your OEM mapping and settings and restore them whenever you want to. The 2 systems are practically the same in practice, it's just the customer involvement is different, brentune is straight forward "simple tool, premade map, install and done", Woolich, whilst technically doing the exact same thing is more focused on custom tunes and generally just provide the tools for you to develop a tune and do it yourself. They do have a library of maps for popular bikes though like Power commanders

Thank you Antares. Corrected. Might you know how quick/difficult it is to instal and remove the wideband sensors for trips to the dealer?

Depends on how your route the wires, but they actually don't need to be permanently installed, if you don't intend to use autotune features, you can just plug it in and hang it down the inside of the muffler. If you do want to use the autotune option ideally you want to have a wideband slot on the exhaust, stock wont have it, but say the Black widow on the gen 1s has a wideband slot in the link pipe. If running stock O2 sensors there is an option to get a narrowband (12mm) to wideband (18mm) adapter however due to the location of the narrowbands that means you'd only be reading the left 2 or right 2 cylinders at any one time, which is not the end of the world, you can tune them separately, probably more accurate too, but in that case autotune may not be a good idea and you're eliminating the narrowbands too. Apart from that it's a couple plug and play harnesses and plugs, not a lot of cabling.

Bren Tuning have a UK dealer now - Motobull. Bren develop tunes that can be dropped in with a Flasher+ handheld. I’ve just dropped one in my Gen2 and it runs really smooth with improved response, better startup and tick over and nicer noise as the inlet and exhaust flaps/valves open earlier etc. If you have to buy the Flasher+ it can be quite expensive, but you can re-use it if you sell and buy a different bike provided you put the standard file back in your bike to release the VIN lock. I moved mine across from my Gen1 so it was relatively cheap to just buy the tune.

I was really interested in the Woolich racing software, but this is really something that is used by Dyno operators to get access to your ECU and will map it on a Dyno, not something you use yourself.  Look up Junction 33 Developments in Lancaster on Facebook, some great results their with Dyno runs at 10%, 20%, 40% and 100% all looking very impressive. In Essex MSS Performance (used to run the Kawasaki BSB team) use it as well. They will normally turn the O2 sensors off in software so you can leave them in place.

There are so many factors that play into this that it's hard to just have an ECU tune that's plug and play. When you factor in air filter, exhaust (slip-on or full), even the altitude where you live, they all play a part in how it performs. Having done this on previous bikes, the best result was when it was done in conjunction with a dyno tune and a tuner that works with your particular software IMHO

It seems like most of the experience that is posted will make comparison to bikes running no 02, or running a narrowband. Since the gen 2 XR has a wideband 02, what it needs for tuning, and how it reacts to mods will be completely different.
