Replaced TPS, bike runs worse!

[mtrdrms]

My long term fuel trim reads -95.5%  Seems a bit off from what Metalguru has...
Also forgot to mention it will lightly backfire on decel around 2-3k rpms.  From my old dirtbike days I think this means that its running lean?

Alot of the gadgets on TuneECU I have just installed seem to be 'greyed-out' is this a normal thing? Have I missed something? Grrrr......

Only "a bit" off ?????

Correct.

Haha!  Well without sounding snotty or dumb, how do I go about fixing my problem and what does the long term fuel trim setting mean?

haven't heard for a while.
Wondering if you have fixed the problem yet or are still reading!!
The trouble with 885's on TuneEcu is the LTFT cannot be set and is greyed out unless it has changed on the newer versions. The way to change the mixture is by altering the map values or the Triumph tool has the facility to do this.
I think you may be looking at the IFT idle fuel trim as this is the only trim which will go to -95! This should start from 0. Try setting to a + value.

Just re-read your thread and if you haven't done it already, the TPS is reading .65. The limit is .66 so could be time for a change there, sorry for missing that bit.

Also according to Triumphs records your bike is still due for the recall work to be done!

Thanks for checking in metal.  I haven't done all of my reading yet but the settings or running condition have not changed.  I will post a copy of the screen in a few but it is the LTFT that reads -95.5.  Ill have to check into those recalls also - what do they fix?
