So if the only difference between the standard tune and TOR tune is the ignition advance and the fuel map is virtually the same in both, why all the concern about running lean when running with the TOR pipes?

 
I used to be indecisive. Now I'm not so sure.

I can't tell you what the difference is, but i can assure you of one thing. When i first got my bike i rode it for a while then put TORS on it a week before i was to get the tune loaded. So i rode it mfor a month or 2 stock, then for a week with tors and the stock tune, then with tors and the tor tune. With tors and stock tune the bike ran like cr@p, and i mean like CR@P ! It lost a good deal of power and wasn't fun to ride. After the tors tune it ran really strong, much more than stock. Whatever the difference is i can assure you it made a big difference.

I think much of this talk about the bike is too lean is over simplification, at best. I don't think it relates to the Pipes at all.

In only one of the Ign tables is there TOR reduced Ignition advance. It's the one related to pressure. The Throttle position Ign tables are
virtually the same. As are the fuel tables.

So, with straight TOR pipes, long or short, you get the exhaust gas out faster, so less need to help by firing the spark sooner. FIring later puts more
push in the power direction and not pushing against a rising cylinder. So, more HP in the system. But, much more TQ at 3000 rpm.

dizz-man:

your note explains the supernatural benefiit of the shorty TOR?

would this affect vibrations as well?

Apparently the shorties are NOT better than the longs as far as power improvement. Bet you're a bit shocked to hear that coming from me, eh? Let me explain. I mentioned how the longs gave no improvement at the RAT forum and some member there began following my posts and telling me how wrong i am and how his made a big improvement. So knowing that there definately was no improvement with mine, at least not anything you could be sure of, i figured that maybe triumph may have changed them. So i checked the part numbers on mine and looked up the part number for the longs on the triumph site and sure enough they had changed. So i assume they realized (probably thru dealer complaints relayed from customers) the longs did nothing compared to the shorts and changed them. Can't imagine they didn't know this already but who knows. anyways, the longs are now different and apparently produce good power like the shorts. Short are much better looking tho, and thats not subjective, it's a fact.

it should affect vibs as your firing later with less pressure for the motor to work against,
not sure how much though
although i think it was daz who commented on a smother ride higher speeds

I can't speak for Triumph's computer controled system [ECU], but in the US auto industries' computer controled vehicles,when you altered the exhaust system[peformance muffler[s] ,dual exhaust,and or performance headers], it decreased the engine's exhaust back pressure which in turn created a lean running condition affecting the vehicle's over all performance.So what ya had to do was disconnect and reconnect the battery which would then allow the PCM[computer] to recalibrate itself and make up for that lean condition.I believe it's now known as "FLASHING".And yes there was a noticeable difference.If it was a carbureted version,you would re jet [larger jets] the carbs.So I believe the same thing is happening when the low restriction pipes [Tors]are added. Hence the reason for the Tors down load or whatever you guys call it.All the down load does is recalibrate [flash]the ECU to make up for that lean condition and,depending on the down load,alter spark timing,increase injector pulse widths, and or increase rpm limits.Atleast,that's how I'm interperting it.But ,because I'm not the brightest star in the sky,what do I know.lol It does sound good though,doesn't it.lol lol Dave!!!

Well, I was just answering about the map diffs, and there is no different map for TOR Long vs Short pipes,. In fact, the map itself
says it's for aftermarket pipes. So, I didn't compare vibration, ie, I didn't run the TOR map with the Long Stock pipes.
I didn't want what daz experienced, so I download the correct map and changed pipes at the same time.
But, the long TOR pipes are probably straight pipes. And Better flow means you can lower the advance on power demand (pressure) for
more TQ.

Short Pipes have the advantage of less weight and better balance. That might have dampened the big buzz if felt at 80 mph.
And the vib could easlily have been pressure pulses against the baffles in the stock pipes.

thanks Dizze. you and davetac have just explained several things to me, and DAZ insight into the short vs long TOR vs New long TOR has put me in the final decision for my silverbird.

I played with some custom ized stockers,, with a bend and weld and what I got was vibration. its going to be back to the simple knockout stockers or the shorts.

so the vibrations can be from the heart beating, not the baffle beating...
