TOR stock tune from Triumph

[craigmpak]

has anyone actually dyno'd a Triumph stock tune (20226 / 20219) for aftermarket exhaust/cat bypass to see what kind of power it actually puts out? I'm trying to understand Triumphs use of closing the secondaries in the midrange in all the gears.

To me the bike seems to perform nicely (20226)... without the ill effects of certain custom tunes. After trying several, I opted back to a Triumph OEM tune. Some tunes felt laggy, jerkey in low rpm maneuvers, more backfiring and mild airbox coughing (backfire at lower rpm acceleration after letting off the gas). Maybe it's just me or maybe the temperature change from one day to another but the custom tunes just don't feel right. So far I've tried a couple of the 20050ToR_dyno ones and the 'trippr3TORSunderseat' with the latter being better than the first.

What is everyone using for their aftermarket exhaust/cat bypass setup? Are more people having luck with certain tunes than others?? Which one has had the best feedback from Rocket owners?

(my mods - TORs + cat bypass + K&N airbox filter)

I had the same setup on my 2005 R3. I got a custom tune from Wayne MacDonald at Tuneboy and it ran very well. Attached is the tune in TuneECU format (hex). The same tune is also in "Tuneboy Modified Tunes" in the Tuneboy format. Run it with the O2 sensor unchecked and the senor disconnected under the right side cover.

Also the results of a dyno comparing this tune with the OEM tune for TORs/cat bypass are posted in:

You can see that closing the secondaries in the OEM tune in the peak torque range costs you about 12 ft lbs.

thanks, i'm going to give it a shot!

i really like this tune .... but my check engine light came on wtf???? I disconnected the o2 sensor, unchecked the box in the map .... wtf?

bike runs well though, kinda low idle after letting off the gas but still ok.

You need to reconnect your O2 sensor, thats why your check engine light came on.
Also put the check back in the box for O2.
The reason is that the dyne tuning was done with the o2 sensor installed.
If you have a R3 touring then try this

this tune you can remove the O2 sensor and uncheck the box
Its a better tune with more H.P.

the tune in my bike is supposed to have the o2 sensor removed because it's the deceleration one ... 20050 Dyno_TOR_cat bypass_decel .....

I cleared the code when I returned and re-uploaded the tune ..... all is well after a 30 km ride. No CEL. And no annoying popping like the stock tune.

The bike pulls very nicely now, wow.

Is everyone running the decel version or are they putting up with the popping from the exhaust?

I've been looking for this very map. I'm going to load the tune tonight in my '06 Classic. I currently have the 20219 map, and I want to get rid of the decel popping. I'm hoping this will clear it up.

Make sure the O2 sensor box is unchecked in the tune before you download it and also disconnect the O2 sensor connector under the right side triangular cover.

Hi Craigmpak, See my posts under Rocket Performance. I did a long post about the Dobeck Performance AFR Plus with 2 Rocket III bikes. Both 2006 models. A Standard and a a Classic. The Standard had 20226 and the Classic had 20219. I tried several tune variants and decided 20050 was the best for my situations.

Wayne MacDonald told me to disconnect the sensor. Since this is now controlled by the software, it shouldn't matter if the sensor is disconnected or not. I did it both ways and never noticed a difference. Before the check box appeared in Tuneboy, the method for keeping the ecu from going into closed loop and use the o2 sensor was to plug a pciii o2 controller into the connector from the ecu. I found that the bike ran smoother with the o2 sensor on but this would cause more backfiring because the sensor leans it out. The main thing with the decel tune is opening the secondaries. The difference in peak hp between the decel tune and 20226 was only about 2-3 hp. Howeve the restriction at peak (torque 2500-3200 rpm) in 20226 Caused a loss of 13 ft lbs.
