Tank range after remap

Discussion in 'Multistrada' started by damodici, Mar 7, 2014.

  1. Yes I know it's the most boring question on earth unless your running an F1 team but I thought I'd ask.

    I just wondered what you guys with and without a remap are getting in range from a full tank?

    my bikes had a CJS remap prior to me owning it and so I can't say what range it had previously, but with standard gearing and cat still in place I'm barely getting 110miles before the light comes on.

    now ok when the light does in fact come on it's suggesting I've got 30 or so miles left so let's say at an outside chance I manage 150miles in total? I just thought the range would be much better than that.

    I'm going to test again on Saturday morning but I've ran this now for the last 4 fill ups and had a mixed bag of riding, last weekend on route to Peterborough was steady back roads for about 60miles with a small 10mile drop down the motorway, on the way back we headed straight back up the A1 at a steady speed (less than 100mph but more than 70mph officer) and still the light came on at just gone 100miles.

    bike was filled up in the cold so technically you should get the best fill up, I fill my bikes upright with me sat on them and even left it a few seconds to settle before popping in some more.

    i just had the impression the multi would / should get you a lot further between fuel stops.

    I may of mentioned before the bike smells rich but I've obviously put that down to the remap, I was hoping by adding a decat and pipe that'd lean out a touch.

    but even so, mileage seems piss poor IMO
     
  2. Adding the pipe and decat will lean it out quite a bit. I assume it had a map from Chris with a pipe fitted?
    Touring, I get 180-190 between fills. Flat out riding around 130-140. I usually top up every 100 miles as my mates with sportsbikes need to do so around then anyway.
     
  3. Yes I presume it was Chris, I'm pretty certain it was actually as I've had some contact with him via email regarding possibly tweaking it after I've added the decat etc.

    The map was set up with the cat still in place and the Akra slip on so nothing's really changed yet, again I'm surprised it smells as rich as it does but maybe you simply have to chuck fuel at the multi to try and smooth out the low end, even then it's not that smooth IMO, but again I don't have the starting point to judge whether it's better or worse than it was. I would say better obviously as I can't see cjs knocking out shite.

    i guess I was just concerned as what with it smelling super rich and couple that with the poor range i was wondering what other people achieved having had remaps or not as the case may be.

    does your light come on around 100-110? It just seems pretty low for the style of bike, my mates KTM SMT was apparently bad on fuel but we're running out at a similar time

  4. I have had a CJS remap and have the Leo Vince link pipe to the Termi stubby , cat removed. Havent pushed the range much beyond 140 miles but have done brim to brim mpg checks and I am getting 50 mpg in normal use. This is exactly the same as pre remap which surprised me as Chris did have to add fuel to get things right .I was prepared to take an increase for a smoother running bike but neednt have worried . Very happy with end result :upyeah:
     
  5. Adding the decat in will make it run richer not leaner?
    I would brim it, reset the mileage counter, strap a fuel can to the rear seat and go and see what it will actually do. The fuel electronics on these bikes are not an exact science to say the least.
     
  6. I did 156 on Tuesday and the light hadn't come on. Recon I get around the 180 mark which I what I expected. Ragging the arse of it brings it down to about 140. I run a full Quat D system without re map.

  7. I get about the same and have seen 58mpg on a tank on the open road at legalish speeds. I find the 2013 is 5-8 mpg better than the earlier bikes partly due to increased efficiency with the twin spark etc and partly because I am often riding one gear higher as the engine is much smoother and 'feels' happy to do that.

    I understand that CJS tunes for maximum power and not maximum economy and generally makes it run richer than it was out of the factory. His main job being setting up bikes for racing that is not surprising. The ideal would be a slightly weaker mixture for cruising - say 3500-5500rpm, whatever it needs for smoothness below that and richer for power above. But it might be a two day job to achieve it!

    I am more than happy with the 2013 standard bike and feel Ducati have done a good job on the engine. On the other hand I was not happy with the 2011 I had before and took it to CJS. He did a good job in smoothing it out and economy stayed the same - 130-140 miles to the low fuel light at which stage I could get in 16 litres. The 2013 is a further leap in refinement with another 20 to 25 miles to the light as a bonus. I have/had standard exhausts on both bikes.

    Riding style is a big factor in tank range. I don't use much brake, anticipating instead. A throttle and brake technique uses masses more fuel but can be fun too!

  8. Well ill see how tomorrow goes and report back, it would seem though that if my lights coming on at 100-110 miles it's at the lower end of the scale.

    do you think riding in touring mode vs sport would make that big a difference?
     
  9. I wouldn't expect any difference. Only the throttle gearing is changed.
     
  10. Thats good news as i find touring mode a little lazy, although i suspect that's the point :)
     
  11. I think some have found that sport mode is actually a little more economical than touring mode.
     
  12. My Fuelly average is a poor 41.8 mpg with a best of 43.8. Don't believe the onboard average figure! My numbers are pretty typical for the 2010 bikes. My big Volvo estate is 10% more economical which just highlights the inefficiency of the 1st generation engine.

    When I used a 2013 GT it was about 7-8 mpg better so they have got the latest engine running much more efficiently.
     
  13. I reckon the Suono will account for the difference Ian, if not in actually affecting actual fuel consumption.........by it's fruity sound urging your right hand to twist harder and faster! ;-)

  14. Well today wasn't much better, in fact it was the worse so far with the light on at 104miles and then 39 in reserve but that dropped rapidly.

    im going to fit the exhaust + decat first and we'll see what happens then, logic says it should get worse but I'm hoping it may break the rule.

    after that I might drop a tooth on the front as I noticed even though I use 6th on the motorway it's barely touched even when hitting triple digits, again will check the difference.

    im going to get nelly to check the bike though just in case, you never know something might be dodgy somewhere

  15. What year bike damo?.........if it's a twin spark bike checking that the secondary spark plug caps are firmly seated might be worthwhile. Apparently there's an issue with them not remaining securely seated....may impact on mpg?

    Failing that I think, as you said, a trip to Nelly would be a good idea.....possibly a sensor somewhere gone faulty e.g. lambda?
     
  16. Its a 2012 Andy , also I'm not sure if the lambda is still active what with the remap is it? I may have that completely wrong so will get Nelly to look at it anyway.
     
  17. Good point, very likely the O2 sensors have been removed or at least disabled when Chris did the remap.
     
  18. I think I need to get the sound down a bit Andy, perhaps too much fruit isn't good for you (pardon?).

    So to replace with another Suono silencer box (is that an oxymoron?) or get the original repacked?
     
  19. Did you Suono come with the 3 db killers? 2 for the decat pipe and one for the end can?
