What are your ECU Trim Settings

What's it ride like Danny?  And what's your fuel consumption like?

I notice your trims are quite a bit different to mine; your LTFT is quite high, 4.15 - 4.18 is more usual, which could explain this.  Raising the LTFT is a bit like putting bigger main jets into a carb.

But if it goes ok, leave well alone :lol:

LTFT on mine has gone to 4.3 and before the gastester commited suicide managed to get the IFT to +23. Although the IFT seems high it is a very fine adjustment from -99 to +99 bit like a 1/4 turn on the pilot screw. The higher IFT cured a flat area on very small throttle in traffic (slight surging) and gastester showed this as a weak area which IFT coped with. These settings vary greatly between bikes as I had another 955 in the other day and it would not run as well as mine on my settings but with a small adjustment it ran very well. Makes me wonder if the hard codings are different as the maps at certain production runs! Would be nice to get into them!! Riding normally I am now getting 45mpg(uk) and roadporn at redline all the way is 32mpg(uk) which looks about right. The tail pipe (carbon can co) has a slight sooty deposit after roadporn for 95 miles, (that was fun).

By the way if anyone is using TuneECU there is no need for the 12min reset as all trims are set when using tuneECU. Only the TPS reset needs a short idle time (about 2mins) to reset the ecu.

Good tip regarding the 12 min tune.  I can't remembert for sure, but I think the early instructions called for it, (I must have read it somewhere or I wouldn't be doing it as it's not reqd for Tunedit).  I see it's now only for KTMs.  Also I can't remember, did I send you one of my tunes or are you on a stocker?

My latest slightly modded 10173 is running well, with no major issues, and good economy even when thrashed.  Trims set static with a CO meter.

Idle is a bit off beat, like an out-of-tune guitar string.

Rough running from 2-3k.

Loud/rhaspy exhaust.

Cut my fuel consumption down to about 30mpg (us) which is bad considering I had it at about 40mpg last I ran it.

Lots (and lots) of soot out the back end. SOO.. it's SUPER rich.

I will say... it goes nice, but only under full acceleration.

I need to trim the LTFT back a LOT, probably to 4.10, or even 3.9 depending.

The ICAV is at -9 and that's the ONLY spot on the adjustment that it won't dive completely to 500rpm on blip, or take a year to come back down.

The bike won't even stay running after a blip test if I try anything lower than -20.

I can't really figure out what IFT does.... I've adjusted from -10 to +10 and there seems to be no credible difference in the way it idles/runs... no real difference in exhaust smell either.

Maybe I should try upping the IFT to about 20, then adjusting the ICAV, and then worry about the LTFT.

I don't know... it seems that no matter what I try, if I do the ICAV first, the other trims mess with it once I change them.

Note... New vacuum hoses EVERYWHERE, ICAV works fine, and it has a new TPS.

So... ?

Using a modded 10173 map modded myself for the riding and economy I do. Have economy for normal everday stuff but using +6000rpm and +50% throttle it opens the floodgates and makes it roadporn for chasing Sport bikes!!!

Dan you need to set the LTFT first. Set IFT to zero and then set LTFT to the LEANEST it will run before it starts surging at idle and standstill.Then up .2 to .6 from surge point. This is like your main jet adjustment in old money.Then set IACV so it drops to idle cleanly but not too quick as it will have on-off throttle syndrome in traffic. Try and do this before airbox temp gets too high as it will alter mixture. IFT is a very fine adjustment and really should be carried out with a gas tester, perhaps a local garage will let you borrow their emmisions tester if you take bike and lap top too. It is a pain needing lots of patience as sonn as you change anything on the mappings etc it changes the settings to a degree, ie make the map richer it makes the LTFT even richer, and vice-versa. Changing the IACV pipes will also make it rich as there are no airleaks now so retrimming required.

my LTFT is 4.6 and she does 50+ mpg, I'll post up the rest of my readings a bit later.

[Danny955i]

NKL, what is your bike setup with? Pipe/KnN or Stock?

Updates in BLUE on page 2.

[NKL]

2006 Model, 10173 map, K&N, Remus Evolution with baffle in, 19t F sprocket, iridium plugs

Injector pulse= 1.833, 1.760, 1.821
TPS=4.1@0.53v
o2 sensor = 0.9 @ -19.2 to -1.2
Idle fuel trim= -8  0.0%  23
speed control step= -8
LTFT=4.6%
Baro= 1006Hpa
Engine load=28%
Ign Coil= 1.471, 1.471, 1.471
Idle= 1120 ish

Smells rich at idle but runs great, no messing about at part throttle at any revs,   pulls from 1000rpm in top gear as smooth as silk, its like an electric motor.
But according to Tune ECU mine has the wrong tune for my chassis no.

[Danny955i]

Yeah, but we all do that... You have almost the identical setup to my bike... but I take the baffle out of the Remus.

Are you running straight TOR tune, or have you modified it at all??

[metalguru]

An interesting point is coming up with these postings.
The TPS value is not consistant as most read outs are coming back with differing values, hence this could be a contributing factor as to why a modded map works well in one bike and not the other.

If only we could gain access to the locked down codes in the ecu we could really have some fun!

[NKL]

Its standard as put in by the dealer. After my holiday I am going to try the correct map for my chassis no.

[metalguru]

HOLD ON THERE....
If it aint broke don't fix it.
Probably your rich smell at tickover is caused by LTFT slightly high. Take it down .1 at a time and try it. Wouldn't go down more than 4.2 though.

[Danny955i]

Really?! I have mine down to 3.7?! And it runs nearly perfect!

Also... it goes 137mph topped out now... Holy crap does it pull in 6th!!!
