V4 Engine Tune V4 Multi

  1. Interesting video, it would be good to see if they do a comparison with the Pani one day.
     
  2. I have had the stage 2 map back from Bren Tune , installed it but been working non stop since getting back from Spain in September , hoping to get out on the bike soon as I can but working 7days aweek has stalled my riding for a bit , only day I did have free was raining and that no way to test a new tune.

  3. Went out today, at last, and tried the new Brentune Stage 2.
    Awesome and a lot cheaper than the full system and better as it's a full tune map, not a road map (evo), the bike just pulls and pulls from anywhere and the throttle connection is almost electric. Its just great ....For or comparison I had the full system , and this better , okay its not loud , but for me the performance gains outweighs the sound and I like steath ..Save yourselves a fortune

  4. Thanks for the update.

    So I am still intending to have the PP, possibly this month apparently. As soon as the run in/first service is complete I think this will be my first port of call.
     
  5. It’ll be interesting to see what the difference is in comparison with the latest updated tune from the factory. I had the ecu update on mine recently and went out yesterday for its first proper run. IMHO there is a noticeable difference. Definitely less thirsty In touring mode and sport is arm wrenching with the front end lifting every chance it gets.
    These bikes are fantastic.
     
  6. The stage 2 is great , I imagine the Stage 1 is more like the factory update as the stage 2 uses the below. The quick shifter seems a lot smoother as well.
    My riding mate commented that he knew it was fast before but now it seemed to disappear no matter what he did , also said he could see the pull has increrased a lot out of the corners as this was the missing bit. The bike used to get bogged if in the wrong gear exiting a corner so the need to down gear all the time with the added explosion of power made the bike flighty ( good tho) , now the power is there all the time even when a bit amiss with the gears. Its brilliant as it pulls and pulls and the 1 to 1 throttle is nice.

    The basics of the BT Tune
    Stage 1 features
    • Raise rev limiter
    • Raised torque limiters
    • Raised load limiters

    Stage 2 features

    • Lower gear throttle torque limiters removed
    • Deceleration fuelling strategy adjusted
    • 1:1 throttle response
    • First gear RPM limiter changed
    • Refined per-cylinder tuning
    • Maximum throttle monitor threshold raised

  7. And how'd you insure that? You declare it as an "ECU flash"?

  8. With the flash it’s in the ECU , with the full system you have non marked end can which is obvious to the stop and check etc . The flash is invisible and removable . I have my van insured with a upgraded map , no issues , I could not get clear insurance with the full system, so sold it on when I changed bikes for the PP .

  9. Can you customise the features? Like if I wanted to keep the standard fan cut in/out?
     
  10. Not that I know about but I did notice that the fan was kicking in at 96 degrees which was better . In Spain hit some high numbers 104 /106 and panicked (pre mapinstall) the bike runs smooth now and for me is a great plug and play addition and the bike runs as it should . Mentioned before but the full system and the Evo map is good but this seems more focused and better .imho

  11. OK, so just to clarify, whilst you had trouble insuring with the full system, the ECU map which is basically what this Brentune thing is, was not a problem to insure? Did they ask about what "stage" you had or anything like that.

    I'm also wondering whether this could fall foul of potential laws in the future about doing anything which might change emissions.
     
  12. Not yet informed them as only just testing as making sure all is good with the map , I will ask the question and say that I have installed a fueling map. This was the same for my van.
    Never seen an emission camera yet mind you. stealth is your key..

  13. What’s to stop you hiring out the handheld at £100 a pop and you get your money back, plus a few lads get cheap maps?!!
     
  14. I think it works like the Ducati upmaps and removes the standard map and replaces with the Bren map. And the standard map is then held on the Bren tool.

  15. Better go call 999 mate......
     
  16. The hand held is associated to your ecu .
    Once the map has been copied and the verified the handheld is for your bike . The unit holds your standard map and the other maps , you then swap between.
    You cannot upload maps to other bikes as the handheld is registered to your ecu .You can sell the unit on but as an associated unit you would reinstall the original and clear the unit so a new owner could go tho the the process above . Bluefin handhelds do the same one unit / one ecu
     
  17. Not really sure what you're inferring by that comment.

    My point was more about how legitimate this is as an upgrade and how insurable it is. You must be new around here and not seen the full system chats.
     
  18. Thanks @Captain

    I'm tempted by this. Not because I find the bike deficient in any way, but because the gains seem suited to road riding.

    I'm wondering if the map will be recognised when it's in for service. If so, is it just a case of reloading the standard map before and putting it back on once you get the bike returned?
     
  19. When the bike goes in for service, the new map would be overwritten by any updates .
    With the handheld you take out the new map. install the old one and go for service, once back put the new map back in , takes 5 mins . Easy as that.

  20. When you say remove the new OEM map and replace with new Brent map, can we assume it's only the engine mapping that's getting changed and everything else stays OEM and up to date, eg things like the latest quick shifter software, latest suspension updates ect general improvement that come over time is something you would need to have. I'm assuming by using the brent tune you are not locking yourself out of these future updates??
    I wonder how we could confirm this??
