O2 sensor wanted

Is your bike running a std factory map? If it isn't, the map you have might be written to exclude any feedback info from an O² sensor. This style of map is very common in the Bonneville world, but I'm not familiar with the Speed Triple crowd.

Have you got TuneECU (free download) and a suitable cable to check what map you are currently running?

 

1. Re fuel consumption - how many ltrs is £15 worth? Really to calculate your mpg you need tankful to tankful figures so that you know exactly how many ltrs you consumed, then you can do a proper mpg calculation. BTW just in case you don't know, there is 4.54 ltrs to a UK gallon. So for example you had consumed 12.5ltrs and you had travelled 140 mls the calculation would go 12.5/4.54 = 2.75galls; 140/2.75 = 50.9 mpg.

2. Regarding the fueling and maps: - I'm not clear what the current set-up is so could you please answer the following: is the bike is full std trim Yes or No. If it's not in full std. trim what modifications have been made?

Have you examined the spark plugs to see if the bike is running lean or rich?

If the bike is currently in full std. trim and if the the std. factory tune is 20490 (check on the bike's ECU, the tune is shown on there, then it should be run with the O² sensor selected. It might be worth going onto TuneECU and downloading the factory version of 20490, just in case the version you are using has been modified or corrupted in any way.

As part of the diagnosis of any problem we need to return it to a known 'good point' which in this case would be factory settings imo.

 

I can't speak from personal experience Jody but If I was getting an accurate 47mpg out of a plus 1ltr bike I would be more than happy.
That mpg does not indicate a major fueling crisis imo.

 

If as you said in another thread all Triumph O² sensors are the same, I've got one here that I took off my 2010 EFi T100.

 

I'll need to check that I can lay my hands on it, after our house move. I'll also need your full name and address to get the postage costs as I'm in France.

I'll confirm tomorrow that I've got it, then we can talk money, perhaps in a private message?

 

Oh! Don't go all private on us now, spoilsports.

 

Discretion dear boy, discretion. That's the watchword.

 

Hi Jody, sorry to hear you still have a niggling fueling problem, happy to hear my instructions on resting map to throttle position helped you out , hope you get this low speed running sorted too.

Cheers

Hi Jody, just a thought, as I've just recently replaced my battery and it's had a big influence on how the bike runs, sounds possible that battery or charging system could have some affect here, as alternator/regulator wouldn't put full Volt's out until engine is spinning at good speed. My bike was a bit doughy when blipping the throttle at idle before battery change, now it really sounds much better and is more responsive, only had new battery in since Thursday not done any real miles yet so can't say what effect if any on mpg, but definitely pulls/responds better all throughout the rev range, Just another view on what might be going ion ?
