Norman Hyde Headers

Yup it's as simple as that ! Just change the setting's in the side box marked sai and O2 sensor and you are done !

 

If you're not confident with TuneECU you could always go down the resistor route.

This kit comes with the plugs for the headers but I have seen people just selling the resistors.

 

Malcolm I've added another link in my original post to the ones Square Deals sell. I've used Square Deals in the past and I can recomend them. If you give them a call they may even sell the resistors on their own... Worth a try.

 

Malcolm it’s the SAI (Secondary Air Injection) that causes the bluing of the headers. I've completely removed the SAI and the 02 for no other reason than it makes the bike a lot smoother on the trottle with all the emissions gubbins removed. I switched off the SAI and the 02 using TuneECU on an old laptop running MS Windows XP connected to the bike with a LonElec USB cable but I've still got the resistors on the 02 but it's doubtful I need them on.

The basic functions on TuneECU isn't really rocket surgery or brain science and well worth getting your head round because it can be used to balance your injection system and other useful diagnostic stuff. There is a lot of info on the net should you decide to have a go with it and I'm sure the helpful chaps in the Triumph community will help should you have any questions on your journey of discovery.

 

As far as I know Malcolm iOS isn't supported. There is a free version that runs in Windows https://tuneecu.net/TuneECU_En/links.html that may be of interest however this isn’t supported anymore, there are also downloadable maps and some other useful stuff on the site. If you can get your mitts on a old laptop it's well worth the effort.

I'm not sure how the Android BlueTooth linked one works not having used it.

 

You need a suitable cable, or OBDLink LX bluetooth scan tool, an Android device, and the TuneECU software (for Andriod) to use TuneECU.

However as I believe your Bonneville is an air cooled model then you can use a cable and are not forced to use a bluetooth tool. Therefore you could buy both the cable, and an Android tablet for less than the cost of a bluetooth device.

don’t worry about the MOT they don’t check for emissions on bikes in the UK....as yet. Re TuneECU: The first thing you need to do is download your current map so you have a backup. You then uncheck the SAI and 02 and upload it back to the ECU. If you need help don’t hesitate to PM me and I will do my best to walk you through it. Some people have had issues getting the hardware drivers for the cable to work but if you get a LonElec one you shouldn’t have any problem. Don’t be tempted to get a five quid one off eBay, some of them have cloned chips and are basically shit... don’t ask how I know!

 

Just received mine and they look fantastic! Can't wait to fit em!
