Termignoni exhaust for M1100s

[chiu]

hi all,

anyone knows if a Termi exhaust for M696 can fit on the M1100s except the ECU??
Thanks.

[ungeheuer]

Yes.  M696 Termi slip-on cans will fit on M1100.

[Buckethead]

Slip ons: yes.

Full system: I don't believe so.

[ungeheuer]

Full system: I don't believe so.

You're right, but you answered the question backwards  .   

M696 Termis will fit on M1100. 

There is no M696 Termi Full system.   But the other way round?  Will M1100 Termis fit on M696??  You're 100%, slip-ons yes, full system nope.

Hopefully the OP is now even more consfused  .

Thanks all of your information.
One more question. What is the advertage and disadvertage of take away the O2 sensor when installing the termi slip-on?
Thanks.

even then you forgot about the midpipe and the exhaust valve on the 1100 which is not on the 696


you could effectively get a full system (albeit a smaller bore) by replace the 1100 midpipe with a 696 midpipe (have to get a Duc.EE to replace the valve motor) and use the 696 termis

Ungeheuer can answer this, but i think the O2 sensors are on all the systems including the full termi 1100 system.

You have to get an ECU reflash with a Rexxer system to get rid of the O2. which would also solve the ECU issue if you get the 696 system instead of a proper 1100 system with DP ECU.

sorry, i don't quiet understand about the midpipe. Is it means that I couldn't fit the 696 termi slip-on directly onto my M1100s? I need to change some parts?
Thanks for your help again Raux!!!

[Raux]

not going to be a jerk here but want to clearly explain

there are 5 parts to a 696 exhaust system, 6 in an 1100

696- horiz header; vert header; midpipe with no valve; left can; right can
1100- horiz header; vert header; midpipe with valve; left can; right can; exhaust valve servo

the cans and midpipes are interchangeable between the 696 and 1100.
IF you put the 696 midpipe on the 1100 you'll need to remove the exhaust valve servo and replace it with a Motocreations Duc.EE electronic piece to fool the ECU.

As to removing the O₂ sensor question.  I'm going to be lazy and give you a low tech, simplified answer.  A few decades ago, Bosch discovered a device called the O₂ sensor.  This device, when read by a computer designed for it allows the computer to constantly adjust fuel ratio.  Manufacturers decided on stoichiometric (14.7:1 fuel ratio).  IMO great for cars, stoichiometric is the perfect compromise when it comes to fuel economy and emissions plus catalytic converters work most efficiently at that ratio.  Bikes?  Another story.  A little too lean for the smoother engine performance we want out of our bikes.  Lean also makes the engine run hotter.

Eliminating the sensor is not an easy task.  As Raux said, the DP ECU doesn't eliminate it on your bike.  If you want to get rid of the O₂ you have a lot of research to do.  Ungeheuer's posts are a good starting point.

Oh, I would look for a solution that maintains the O₂ sensor, but moves it to a richer ratio.  And the cat (if equipped) would go.

Correct.

[Raux]

THe Powercommander V comes with a part that changes the O2 readings so the bike rides a bit richer in the closed loop. (it's selectable, but Dynojet has done the work to get it right. I think 13.2:1 is what it is.. or close to it)

BUT the powercommander doesn't raise the RPM limit

The DP ECU does, but keeps the O2 loop

the Rexxer remap can eliminate the O2 but there were issues early on, I think they've fixed those issues. It can also raise the RPM limit.
In the end, if you are need a place that can build a custom map for your bike with a Rexxer unit... you get everything you want.

Or you can get the Rexxer remap with the base DP ECU remap, eliminate the O2, and add the PC V to tweak the map.
Then again you can get the Dynojet Autotune back into the system, which are two wideband o2 sensors that you can adjust to the A/F ratio you want and let the PC V tune the bike for you.

There are a lot of options to say the least.

Meh... you're close enough  , 13.6:1 is Dynojet's optimizer preset AFR.

You're right about the PCV.  And you're right about your M696 DP ECU.  But on M1100 the DP ECU does NOT raise the rev limiter, lights ablaze and fuel taps off at 8250rpm regardless.

the Rexxer remap can eliminate the O2 but there were issues early on, I think they've fixed those issues. It can also raise the RPM limit.

No more Rexxer O2 elimination issues, all good now.  And yes a Rexxer reflash can raise your RPM limit, mine's at 9,500rpm.... other people have raised the limit higher still.

Indeed.  There's plenty of useful info around here, the search function is very friendly  .
