Help Required Explaining Re-mapping Etc.

Hi, firstly saying it had a re-map is incorrect, when the Triumph dealer fitted the extras, what happens is they upload a different factory map, not a re-map. What takes place with a dealer map is that it allows the correct fuel/air mixture, so the machine rides smoothly. The Norman Hyde Toga exhausts on their own do not require any change, they are fit and go. The rest of the modifications will have limited benefit from the arrow map, however that map is specifically for the approved Triumph Arrow Exhausts. A re-map, or ECU flash as some refer to it, is where the machines ECU is connected to the dynometer on a rolling road, using as an example the Woolwich Racing Map, firstly a reading is taken on the machines stock readings, then that information is stored safely on the system, the map is then customised onto the ECU, the bike is then run up at different speeeds, it shows on the graph the original readings and the new readings on the re map, it takes a half day or more to set it all up correctly, and you can see the difference in BHP increase and smother running. The question you ask regarding the ECU recalibrating itself, this is correct for the newer machines, however, as yours is a 2008 model it will not recalibrate by that method. Changing the silencers will not require any recalibration.

 

If you change your silencers now, you'll need a new professional remap. Your current Arrow map is specifically for your old setup. The idle trick only lets the computer make tiny adjustments at idle, not across the whole rev range. For different pipes, a full remap is the safe way to go.

 

There are many aftermarket exhausts that do not require any re-mapping at all.

 

The Peashooters look lovely on a Bonneville. Speak with Arthur Macdonald at Moto Legends, he has owned Norman Hyde Ltd since Norman Hyde retired a few years ago. The Norman Hyde partnership still runs, selling his books. Arthur will confirm that fitting the Peashooter exhausts may give some popping on the overrun, but nothing detremental, personally I love that sound anyway. You could always send the ECU to a reputable tuner for a re-map, stating what mods have been done, and a new customised map can be installed. If you want to go that route them PM me, I can let you have details of an excellent specialist that can do it for you. You could ring him and have a chat, he is very bust however, it may take a few days for him to get back to you. Thinking about it, I seem to recall Joe fitted some to a bike he had a few years back, if he reads this he may be able to say how they performed for him.

 

Any quality silencers will be fine. I would stay away from the cheap ones, but the Norman Hyde range is fantastic quality. Consider buying the Dealertool, it costs £65 and will enable you to do a fair amount service wise. Have a look at their website, all you need is a laptop running Windows 10 or 11 for it to function. The beauty with the Dealertool is it will not make any changes to your bike's ECU, in effect you can't mess anything up. Hopefully, your machine will be ready for the better weather.
