20055=MORE Power,DragonEye WAS RIGHT!

[RiderRocketman]

I finally took a look at all the secondary throttle plate restrictions in all the Rocket tune maps courtesy Tuneboy.

What I found was Drago's claim that the 20055 was "full power" is correct... to a point.

Take a look at all the power restriction maps...



The 20055 map does give more power over some others but still restricts significantly in the first 3 gears (only 4th and 5th are truly at 100%), BUT these are also the same restrictions in the standard tunes for a stock Rocket (both standard and classic). The 20055 tune does have advantage over the other aftermarket pipe tunes, which actually restrict in all gears, mainly in the middle of the RPM range.

The Classic tune restrictions are basically the same as the standard Rockets. I haven't a clue what that 20099 tune is for. The description is vague, just for "aftermarket pipes," which I think the 20097 is pretty much the same description. The power restrictions are different though. 20099 has more gradual while the 20097 tune restricts more steeply around 2000 RPM.

You guys in France and Germany already know you get restricted, so now here's your proof. The French and German restrictions are the same for standard and classic Rockets, but the Germans get restricted earlier in the RPM range. No fun on the autobahn. I bet the guys over there are clamoring for Tuneboys if they haven't already yanked out the secondaries. :lol:

Thanks, Now, me being the layman that I am when it comes to some of this...

Running with the TORS and Cat Bypass, which I assume to much more free flowing. since the 20055 tune shows full open for 4th and 5th and the upper RPM range of 3rd, does the potential exist for a lean running condition where I mostly run between 2500-3200 RPM?? than the 20054 Tune.

Excellent work... Bears out what I feel on the road... Had 20050, 20054 and 20055 in my bike so far... 20055 seems to deliver the most power to me... The graphs bear this out.... Tunboy on the way...

k, think I'll leave mine alone (it has the 54 tune)till I decide on Jardines and Tuneboy.

 

[lonerider]

So standard tune from stock, with catbypass and TOR,s may be creating fry lean? Can this be damaging in some conditions, eg long haul (long term mid revs under load) or conversely, (mutiple changes to revs) tight twisties. I have this above config with tune pipes cat and am considering foam air intake set up and new tune?? What should I do as I,m more interested in good sound and no more scary herbs, maybe better econ?

Or am I creating a new interpretation of the graphs as a function of my intelligence (or lack of dependent on throttle/air/spark input).

 

[RiderRocketman]

Have no worries about going lean when you're using the standard Triumph tunes. If anything the Triumph tunes are overly rich because they want to play things safe.

The main reason I'm showing these graphs are just to compare how Triumph is restricting power among all the tunes.

Now for a more technical question. Does anyone know if the ECU is dynamically adjusting the air/fuel mix based on these secondary throttle maps or if these maps are just used to tell the ECU how much to open the secondaries?

I ask this because if the ECU is not making fuel adjustments based on these maps, then changing these maps via Tuneboy without changing the fuel maps would throw things outta wack.

thanks for simple answer, your smartie next question could be better asked what comes first chicken or etgg? :lol: :wink:

e.f.i.

g-man ---how much longer til we are all putting bosch wide band sensors into a bunge on each pipe and can run in a closed loop system? let the computer figure out a/f ratios as the bike runs? not some predetermined table of tests in england's environment !---john

 

[tmiller]

Ok, now is there any other ECU available that we can adapt to the rocket? As john says, having wideband O2 sensors in each pipe would be the ideal setup if the CPU can handle it.
