cough when blipping the throttle

not sure about that Kevin, i've got the Arrow cans on though,somebody running the standard cans would know..by the way i clicked on your location Newport thinking it was Newport in Fife, but it's coming up as Newport in America!

 

ah yes putting south wales in makes a differance! you will know Bevan m/cycles in Cardif then,i got my speed triple from them

 

Could well be an air leak in the exhaust. I had this on a VFR some years ago, which was cured by resealing with domestic silicone sealant. Lasted for years like that.

 

Hi Kevin, welcome.
Have you bought the bike recently second hand? Just wondering whether previous owner might have had Arrow cans and put standard ones back on to trade in, so might still have the wrong (Arrow) map loaded on the ECU.

 

Yeah, not my nearest dealer but bought a few Triumph accessories from them, talking to them on the phone they seem to be on the ball.
I you're interested you can read which map is loaded yourself using some free software and a cable (£15 approx).
More info starts here and here.

 

Hi Kev, I'd be cautious of any software you get with the cable. The guys at TuneEcu make a big deal (rightly so) that their software is free but shouldn't be available anywhere else. Have a good read on their site about the drivers you need to install on your laptop to make the cable work. Drivers supplied with cables are often wrong for use with TuneEcu. Get that bit right and the rest is plain sailing.
Recently changed my map for the Arrow cans and also balanced the throttle bodies via TuneEcu, no problems.
If you ever need to change the map take note of the IMPORTANT instructions to pull fuse for lights and also connecting car battery. If voltage drops too low the upload will fail, there's recovery available but you don't want to go there.
Map upload is the only operation you need to take those precautions and has any risk (IMO). Reading map number, error codes etc etc is all dead easy.

 

Hi Kevin, please confirm your SpeedIII is NON ABS and within the VIN numbers #461332 to #537880, with standard exhaust (and air filter). If your VIN number is outside that range you need a different map.
If yours is in that range then the current map you have loaded is close..... but no cigar. That map is for 91RON fuel, in the UK you would be better running a map for 95RON (map 20483 if the above is correct), there's probably not much difference in the maps but might be worth a try. Also did you check for any error codes while you had TuneECU connected?

 

Just be careful to follow the previous warnings to ensure you keep the voltage up while you're doing the remap.
Do you know any of the bikes history?
If it's had different exhaust and reverted back to standard it might be worth checking the SAI valve is not still disabled either physically or by map (there's a tick box in TuneECU). Less likely but O2 sensor can also be disabled. Both should be active as standard (boxes ticked in TuneECU).
TuneECU also tells you how many times the ECU has been remapped, so will give you an indication of it's history. As your current map isn't the UK standard I'm guessing it may have been modded and brought back to standard... but may be not fully/correctly.

 

Yep, always a bottom clenching few minutes.
Pleased it went well and sorted your glitch.

 

Well that's good to know.

 

Nice one Col C

 

Hi Kev, glad it sorted the problem. Must say I'm slightly surprised it made so much difference as the previous map was almost there, just for lower octane fuel. Remapping would also force the ecu to run an adaptive reset, so that would also improve the bike setup and may well have a lot to do with the improvement.
If you feel it 'go off' in the future you can run a reset without the need for remapping. It can be activated in TuneECU or will do it by leaving the bike on sidestand, start bike without touching throttle and leave to run for about 10 minutes. I prefer the TuneECU method as it gives a confirmation when completed.

Have fun, go wrong it's neck now.
