M796 race ECU

[Dochunt]

Does anyone have any experience in changing to a race ECU on 796 without changing the exhausts?

It came as a package with a freer flowing air filter and Termi cans. Not sure what if any benefit you'd have with just the ECU. Might be too rich as well. Even with the whole $1,600+ package you only gain 3 BHP although it will run a bit smoother down low. For that benefit the price was too steep for me. YMMV...

BTW, there were DP ECU's with and without ABS, so watch that too!

Any other way you know of to smooth out the lower rev range.
I have the 14T front sprocket.

install the vizi-tec exhaust valve emulator

So, you are saying that a 696 mid-pipe and flapper delete is a cure for roughness under 4,000 RPM on a totally stock bike. e.g. his and mine? Was thinking a reflash of the stock ECU for richer bottom end was a better answer?

FWIW I had my 796 reflashed end of 2011 and was totally disappointed in the result.  It was slightly smoother but below 3K revs it's still a beast.  Lots of info in "closed loop" and other threads.  I got used to it, when moving slowly in traffic or parking lots I just keep the revs up and slip the clutch.  Nothing failed yet after 29000 kms

yes . . . did it to 3 customer 796 and 3 MTS1200 and 1 Diavel, idle smooth and acceleration one big gulp of air no hesitation

I will get it done.
If it works it will remove the only big gripe I have with this bike.

Ok, I just ordered it.
Should this be installed by the dealer or can I do this myself.

Do you understand that you need a 696 mid-pipe?! 

[Raux]

Not necessarily iirc the flapper valve default is open so you could just unhook it and remove the motor

You can do it yourself.

1. Lift seat
2. Find connecting plug
3. Unplug factory harness
4. Plug device to factory harness
5. Dismount RH exhaust pipe
6. Take flapper valve cover off
7. Pull cable until you can take it off
8. Valve will remain in the OPEN position
9. Take motor off bike, loose about 1.5lbs
10. Install seat
11. Turn IGN to ON and start, NO check engine light should be on since ECU thinks everything is OK

BTW, instructions do come with emulator

Now, if you want to completely take valve off, take Dremel® Tool and mill the screw heads off and take out

So basically one physically removes the exhaust valve and the Emulator tells the ECU that everything is okay?

Yup

And now the bike revs better in the low range and breathes easier?
And there is no bad affect on the bike?
