I have an 00 Sprint ST i want to put an exhaust on and the dealer said it's a labor intensive (removal of plastic, tearing into throttle bodies, etc)....he told me 02 and up is a simple plug in deal, but not on this...True or not?
Their not. Triumph used the same Sagem fuel injection ECU from 2000 to 2004. The big difference in the tune is that from 2002 on they used a 'closed loop' system that used and o2 sensor to help with fuel to air ratio adjustment. But it was only used by the FI during idle. The upload procedure should be exactly the same.
Now, one more question..If you have the offroad tune downloaded, do you need to have the new exhaust on it when it's done? In this situation, I had trailered my sprint 240 miles round trip only to be told the above, plus the fact they claimed the exhaust needs to be on it when its done..True or is this just a basic download? Might have to make at trip 100 miles in the other direction to go to a different dealer
Sounds like the Service guy at that Dealership is either an idiot, or trying to run you off.
The bike will run best after the TOR tune when you have a less restrictive (i.e., K&N) filter and a flow-through exhaust. The exhaust is the biggest factor, though.
The ECM has no way of knowing what is connected to the bike that isn't electric, and very few things that are electric. So the map update doesn't depend on what is there. However, as mentioned above, the mechanic will want to run the bike afterward to make sure it works. And...
One more thing. The '99 - '01 bikes featured an ECM that had tuneable fueling. So, when you find a wrench that is worthwhile, make sure they do the map update, then run the bike with an Exhaust Gas Analyser hooked up. They should tune the CO levels to specs.
I had the above done to my '00. Fuel economy and felt horsepower went way up. Of course, since I had bought it from another fellow, I figured I'd have it checked out.
Get this. My bike (an ST) with a Triumph Carbon TOR, contained a Daytona w/ stock can tune. Never have figured out the how and why of that one.
