Mivv Collectors/decat - Engine Light On

Discussion in 'Hypermotard' started by Bradders276, Oct 4, 2014.

  1. Hey guys. I'm new here, and 6 weeks ago bought myself a 2009 Hypermotard 1100. It was standard, but I have recently made a couple of small mods. I drilled out the airbox lid, which made a significant improvement. Yesterday I fitted a set of Mivv collectors with decat pipe. The bike runs a lot smoother all round, and a bit more of a growl to it. The only issue is I now have the engine management light on permanently. To be honest I literally cut the lambda sensor wires and removed it. Should I resolder the wires and refit the lambda in place of one of the plugs? Will this cure it? Or will I need an ecu reflash? If so how much would this cost?

    I'm pretty happy with how the bike is now, and don't want to spend much more. I may however get a replacement mid pipe to remove the exhaust sensor. Is this a recommended mod with a standard ecu?

    Thanks in advance

  2. I bought some 02 eliminators off eBay 20 odd pound. Gets rid of the warning light. came with the bolts to plug in the pipes too. I'll try to find the link but I have posted it on here somewhere
     
  3. Absolutely definitely go with a reflash - expensive but worth it...my reflash:
    1. marked off the o2 sensors.
    2. Disabled the flapper valve (also drilled out) - removed motor as well.
    3. increased the redline by 500 rpm
    4. increased midrange (by a sizable amount as well)
    5. Improved petrol economy by about 20% or so....

    From an engine setup ive got about the same as you, twin termi's, drilled airbox and decat. You can see the midrange torque...
     
  4. The refresh is definitely the way but I used these

    Ok as a quick fix turns off the warning light and helped smooth it out a little at low revs. But nothing like a custom tune would do.
    CJS said they can do a generic reflash for a Siemens ecu £200 but probably best saving for the full tune.
     
  5. Does the HM 1100 2009 use the IAW5AM?

    If it does drop me a PM, as I can help ;)
     
  6. You sure you can't do the Siemens :'(
     
  7. Sorry - my kit is just for the IAW5* family of ECU's
     
  8. Hi Guys. Sorry for the late reply. Busy few months and forgot I had signed up here. Whoopsie! I am now in the process of coring out the exhaust. Is it worth removing, or disabling the flapper valve? I will see how it rides after, as could do without the expense of an ecu reflash at the minute. But that might be a treat for the summer ;)

  9. Just drill out the valve itself....you can leave the motor connected for the moment then....
     
  10. As for ecu I'm looking into getting an rapidbike evo. They've had a great write up and are more popular than power commander in Europe apparently. There's a thread on ducati ms about them for the 821 and I've spoken to John Warrington motorcycles and a few of his customers and they seem to love them. Got autotune built in so no matter what mods you fit it will always tune to suit. The other benefit is you can fit it onto your next bike just need a new cable.
     
  11. Awesome thanks guys! isaachunt, any idea how much the rapidbike evo is for the 1100?
     
  12. I think 400 is what CJS charges for a full day on the dyno....better spent that way I would say....
     
  13. I haven't fully rulled out cjs tune but rapidbike offers a very good alternative from what I've researched.

    I think I was quoted £475 for cjs plus I got to ride to bristol spend a full day there and ride back (not so great if the weather is shite).
    Thing is the dyno is tuned to suit one set condition. If your riding conditions or modifications change the rapidbike changes for you. Also when you change bikes you take the rapidbike with you, so the money isn't totally lost.
     
  14. Agreed but from personal preference its the single one thing that changed my bike the most in one hit. I think normally once someone has set their bike up (moreso from an engine setup point of view) they never change it....this is why my RSV4 will be going there (scheduled for april) but as I know its going im going to see if I can get a full system on there first....
     
  15. Yeah I'm just super tight with the money (plus got to get valves and belts done soon). I just can't seem to get my head to kiss goodbye to almost £500. If it was £300 I'd be there.
     
  16. Its one of those things you kinda have to experience.....reckons he can get an extra 15 brake out of the RSV - im there! maybe more if I can get a decent front section on.

  17. I can do you a postal service using RexXer maps. Been pretty successful so far, with good feedback. Done quite a few Siemens bikes (M1100's especially) as the ECU is a tough one to crack. £230 all in delivered back to you.
    Tbh, unless the Rapid Bike uses new wideband lambda sensors, it doesn't appear to do, then there's little chance it'll be able to monitor and/or adjust fuelling accurately on the fly. The stock O2 sensors don't react quick enough nor give accurate enough readings. The auto tune kit that piggy backs the power commander V, uses new wideband sensors and still doesn't really perform that well. The data transfer of readings/parameters can't keep up with the engine speed, so by the time the adjustment is calculated/done, the motor conditions have moved on. That's why mapping is done using a brake dyno to hold the engine under a steady state load. You can't get accurate AFR readings on the fly, just a reasonable indication of what is going on...
     
  18. Why do people keep giving me more options :) (to be fair Chris CJS said he could do a generic reflash but couldn't guarantee results).I'm not exactly sure about the rapidbike but from what I've read it does use narrow band sensors and you ride and save the map then repeat and it narrows it down to the best afr it can? They do sell wide band sensors add on (think it's called my tuning bike) from what dimsport told me I don't need them but they would enable the final map to be obtained quicker.
    With the hyper 796 apparently they load in a very close map that they've done on dyno and then it gets fine tuned.
    They do a race version too which does things way too complicated for me to understand.
    Like I say I'm no expert and still researching. I just like the idea of the flexibility of it (if it works).
     
  19. I'll 2nd the custom map route, no brainer for me as it's the best £ per smile value achieved in performance/ride improvement.
