Lamba sensor removal

Is this a Triumph dealer that's worked on the bike? Can the bikes history be researched in the dealers database/service records to see what mapping updates have been carried out?

 

May be worth booking yourself an appointment at a Triumph dealer to get it hooked up to the diagnostic equipment then. I had a couple of modern Guzzis and they were both fitted with lambda sensors and EFI and it was only by hooking up the electronic diagnostic kit each time it was serviced could the injectors be balanced, etc. If the previous owner carried out his own servicing did he buy the software and suchlike to carry out this part of the adjustment process? Do you have the sensors that were removed? If the garage that serviced the bike this time have the software to remap it could they not refit the sensors for you and sort the tune and warning light?

 

By Lamba sensors , are they also called air sensors in exhausts,? mine has had them removed, and air induction kit fitted. I took my 2009 Bonnie to a rolling road specialist (he sponsors amateur racers, good guy). Triumph told me sensors should not be removed. Specialist said he tunes for 13.6 to 1 for fuel air, knows the Triumph guy well but does not agree, and further said if ever you do have Triumph service yer bike instruct them not to remap as they sometimes do without telling customers if a new map is advised by Triumph. He also got me 15 more mpg! Using his computer he showed me how the power is delivered smoothly. A test first to see if anything needs changing is £25 and a printout is provided. After any work another printout shows the change. Well worth it to check wether my newly aquired bike was running efficiently. This guy is in Malton North Yorks but I would think you know of a Dynabike guy in your area. I was so impressed I had my carbed Harley tested and sorted. Different bike!

 

I think Crispey is referring to the O² sensors in the exhaust manifolds. It sounds like your bike was modified very similar to mine.

I think the bike shop you took it to has checked the ECU to see if it has the most up-to-date TRIUMPH map and may well have fûcked up the previous map (most likely TTP) .

The first thing I would like to say is that I have done many thousands of miles on my de-O² sensor bike and she runs beautifully. No problems whatever. I also removed the Air Injection (AI) system, installed a free flow air filter and long free-flowing pipes. She runs cooler than std. (so less blueing of the pipes).

Basically the garage that did the work has, imo, fûcked up your bike but it is easy to put it right. If I were in your shoes I would be contacting Mike at Triumph Twin Power (TTP) and telling what has happened, giving him the name of the previous owner (so he can check his records to ensure that the re-map WAS purchased from him and which one it was) asking him, if he would be so kind, to supply me with another copy of the map. Also at the same time I would contact the previous owner and explain what has happened and ask him if he could e-mail you a copy of the re-map, if he still has one.

So, imagining that you now have a copy of the re-map and assuming that the AI system O² sensors are fully removed, you just need to re-install the re-map. To do this you will need an OBD (OnBoard Diagnostic) cable - you can buy one from TTP for about £18 - and a copy of a free download called TuneECU.

Install TuneECU and the drivers for the cable on your laptop. Connect both the laptop and the bike (via a battery charger) to the mains. Connect the laptop to the bike using the OBD cable. Then fire up TuneECU, take a copy of the map that is currently in the bikes ECU and save it on the computer. Now install the re-map, ensuring that both the AI and O² boxes are unclicked (tell the bike that these item are no longer in the bike so the EML will not be tripped on.

Once the new map has been installed, disconnect the battery charger and start the bike DO NOT TOUCH THE THROTTLE !!!!! during this process. Allow the bike to tickover for approx 15 mins or until the green bar indicator in TuneECU says it is complete.

Once that is done, exit Tune ECU, disconnect the OBD cable from the bike and the laptop and go for a ride on your bike - and ENJOY.

So what will you have achieved?

1. You will have copies of the std. Triumph map and the re-map on your computor, should you ever need to use them again;

2. You will have re-mapped your bike to suit the configuration it currently runs;

3. You will have learned something new !

Cheers and the very best of luck to you. Personally I wouldn't use that garage again as they don't know what they are talking about.

Hi Crispey, you might find it interesting to know that these bikes don't have a 'choke' at all. The control you've been using increases the tickover speed and that's all. No change in a/f ratio.

 

My Thruxton ticks over at just over 1000rpm. Speaking to a Triumph dealer today he was telling me that it was important not to touch the throttle before starting as it would alter the idle setting. Apparently the EFI compensates for any fuel injected by twisting the throttle before hitting the starter.
I use position 2 on the fast idle from cold, position 1 when warm and ease it in from position 1 when on the move for about the first 1/2 mile.
