What are your ECU Trim Settings

[Bixxer Bob]

If you're using Tuneboy, Tunedit or Tune ECU, please have a look at your stepper motor and long term fuel trim settings and post them up here along with a short comment on whether yours runs good or bad, has the 2-3000 light throttle lumpy running etc.  In fact anything you think might be relevant.  If you've done some work please list that too and whether it improved things or not.  I'm hoping that once we've got a few posts we might be able to spot trends.

Also, try to keep it to just bullet points for simplicity.  Thanks  

Edit: Also, please indicate whether the O2 sensor is connected and working.

Triumph Tiger 955i 05.
Gearing= front 19t rear 46t. (5500RPM @ 90MPH)
Michelin pilot road tyres.
Carbon can co. 3 sided can and link pipe.
Standard air filter, airbox baffle removed.
12.5 stone rider, 5'9".
Replaced fuel pressure regulator as rail pressure high and immediate improvement in running from rich and smelly at idle.
-------------------------------------------------------------------------------------
TuneECU v1.7.2 10173 TOR Map.
Injector pulse= .564 .563 .567 Closest that they have ever been.
Throttle (TPS)= 2.2@.61v.
O2 Sensor     = Output volt=.940 @ 0.0 related fuel trim, closed loop. Now open loop at idle due to A/f map edit.
Idle= 1000 @ stepper position -20.
Idle Fuel Trim= -3.9.
Speed Control Step = 0 to +1. Very narrow control now, must be good. Now zero
LTFT  = 4.1%
Intake Temp = 46C @ 1.98v Motor sensor=.59v (temp high because stationary)
Baro = 1050 Hpa
Engine Load = 23%
-------------------------------------------------------------------------------------
Idle Fuel Trim = -16.4. Edit Now ZERO as map edited in A/F 1.
Stepper Motor = -24. EDIT now -20 as map edited in A/F 1.
Long Term Fuel=4.1 Good for performance. 3.9 for economy.
-------------------------------------------------------------------------------------
Warm Up Map.
-10=0.25 -4=.20 4=.15 14=.05 24=.05 34=.05 44=.05 54=.05 64 to 130= ZERO.  This has to be lowered due to TOR map & LTFT running richer.
-------------------------------------------------------------------------------------
Idle Speed Fluctuation =1000 to 1070RPM
-------------------------------------------------------------------------------------
Gas analyser broken so used nose gas analyser.(No deep breaths here please)
Exhaust not sooty or smelly.(Greyish tinge after Roadporn).
Butt dyno =very lively with good and smooth acceleration with low throttle/ low speed very smooth no on/off throttle syndrom and easy ride in traffic. No spluttering 2.5 to 3.5k rpm, no backfire on over-run. No chuffing on idle. Lifting front wheel at will (poor will) on hard acceleration.
Still have to test for MPG over time but looks promising. Reduced warm up map because of wind chill on engine. (temp guage does not go up very much)! May not be the case in warmer climes. Smooth clean idle at last.
PLEASE NOTE This trim worked so far for my bike but each bike could need different trims for different riding styles/weight etc so don't take as gospel this is the ultimate cure. It has certainly cured all the known running probs ie, rough idle, slow speed, and smelly exhaust, on my bike, so cannot take responsibility for what the results are on yours, but the more info the better.
-------------------------------------------------------------------------------------

EDIT:- MPG= 40.1 on a mixed run from crawling along behind cages, motorway, A roads and a 10 mile flat out redline hooligan fun roadporn!
------------------------------------------------------------------------------------
EDIT:- In MAP EDIT TuneECU go to idle map
-10=1700  -4=1650  4=1600  14=1500  24=1400  34=1300  44=1200  54=1100  64 to 130=1000. This will help smoother warm up. Not as rich due to warmup map.

EDIT:- Clean warm up now, will improve MPG overall
-------------------------------------------------------------------------------------

Go to AF/1 map.
You will see some boxes coloured purple in the 1000-1400 RPM and 0-27% Engine load, change these to read 14.45. this will help set the Idle Trim for smooth idle as it knocks out the CO sensor so not fighting each other for Idle mixture.
Long Term Fuel Trim can be affected mine will run down to 3.9 from 4.2 and will give better economy but beware of going too lean, needs a rolling road to set properly. LTFT will alter the WHOLE map, be careful.

Idle Fuel Trim will have different settings but set to your own bike so exhaust is not smelly rich and idle smooth (takes a bit of time this bit).
LTFT, IACV and IFT are INDIVIDUAL to each bike and may not correspond to my settings.
-------------------------------------------------------------------------------------
PLEASE NOTE THESE SETTINGS WILL CHANGE AS I EVOLVE THE SETTINGS.
-------------------------------------------------------------------------------------
Just to be fair I have loaded latest TOR map 10173 and made settings with that map and is accessible to all.
-------------------------------------------------------------------------------------
REVISED 09/04/11 IN BLUE PENDING ROADPORN.
-------------------------------------------------------------------------------------
EDIT:- A/F1 Map= At 5 to 6000 RPM @ 41 to 58 Engine load now reads 14.5. Leaned off for better MPG @ 90MPH!! Was 29MPG@90MPH.
-------------------------------------------------------------------------------------

EDIT:- A/F 2 Map. Lowest value now 12.50. 1300 from 5000 to 10000RPM, also to lean off for fast cruise.

UPDATE 05 MAY 2011

IDLE -10=1450 -4=1450 4=1425 14=1375 24=1325 34=1225 44=1100 54-130=1050

WARM-UP
-10=0.05 -4=0.05 14-130=0

IFT=-1.6
STEPPER=-25
LTFT=4.0
A/F1 MAP=1000-1400RPM & 0-27% LOAD=14.40

IDLE FLUCTUATION=1040-1090RPM

RESULT.Huge amounts of mid range grunt up to redline and progressive throttle.Warm-up is a slight bit lumpy but not for long, not even noticable if ridden straight away. Pick up from stop very quick and roll on from 60mph to 130 in top seems alot quicker than before. (butt dyno only).AT LAST 43.6 MPG (uk) on very mixed riding including roadporn and motorway. (even got a speeding ticket DOH).

Been playing again and got some interesting figures back.
For those who like the 1200rpm idle I thought I would have a play.

Warm up map =-10=1450 -4=1425 4=1400 14=1375 24=1300 34 to 130=120.

I had it all worked out on this day, laptop in the topbox all wired up, gastester strapped to the bars and off up the road I went. Before it all went pear shaped I managed these settings.

Idle Fuel Trim=26.6
LTFT =4.3
Stepper=-20

These settings changed alot from my last ones as I was doing it live and making adjustments on the ride. Managed 46.8 mpg (uk) and performance was good all through range as before. Mixture seemed consistent through all throttle and speed positions.

UNTILL the strap holding the gastester broke sending said instrument crashing into a million pieces on the road, at about 90mph!!!!
Oh well good while it lasted....The lengths I go to.


UPDATE         AUG 25-11

Change to clean up warm-up map

-10 to 44 = .50    54 = .25   64 = .10    74 = .05

IDLE =  -10 to 44 = 1550   54 = 1400  64 = 1300  74 to 130 = 1200

Comprehensive writeup Nige, thanks!!!  :D

[Danny955i]

THAT is the sort of information I need.

Bravo!!!

What 'baffle' did you remove from airbox? I'm picking up a standard filter from my dealer tomorrow to replace my K&N and I'd like to give this a whirl.

Did you simply cut-out the plate where the 2-holes are between the air-filter and the box inlet?

[metalguru]

Yes spot on.
Some of these are metal ie,855 but my 955 was plastic. Just went round with a soldering iron slowly, through the air filter hole till the plate was weak enough to be hauled out. (Don't undo the screws on the outside of the box or the captive nuts will just spin). This leaves the mounting edge which just pulls out. Needless to say all plastic swarf MUST be removed and the inside of the box spotless. I don't know what the benefits to removing the plate are perhaps it is an intake noise baffle. I noticed also there is only 1 intake tube rather than 2 on the 855 and the trumpets are shorter on the 955. The only downfall I can see is the airbox temp sender is more exposed with the shorter intake trumpet.
Good luck and hope the data helps to eliminate some of the injection system downfalls. I am still experimenting so data can change.
The airbox mod has been datailed on another thread with pictures.

Had a PM from Hassan to say your settings had cured his black smoke issue, but still a bit rich.  He's on the right track.....

Great news, happy that it has worked.

Keep an eye on the settings as they will change as I learn more and change the tune for the better.

[ChazzyB]

Am I being dim, but how is LTFT adusted or even reset? The element for it is greyed out when I run TuneECU up.

[metalguru]

If you are running the latest TuneECU it did on mine too. Try earlier version if not PM your email and will try to send you older version

[Sasquatch]

Need some serious help and education.

My bike is running sickenly rich.  Checked the fuel pressure and it is sitting pretty at 43-45 psi.

Here are my trim settings, and I can not seem to get the fueling to lean out.  My questions are in () following the settings.

2001 Tiger, latest tune for vin number installed.  Race can, modded air box.

Version 1.8.7

Injector Pulse: 1.054 1.071 1.042
Coil:  1.84 1.88 1.84
Throttle:  2.0  .61V  (is this not supposed to read 0 after resetting TPS?)

O2 Sensor:   .785 to .850  -19.2    (what is the -19.2 number)

Idle:  1200    -10  (what is the -10??)
         3.1%    41   (what are these??)

Long Term  3.4%   (which way does the number have to go for leaner?)

Temp    68C  1.04  .49
Baro:  930 hPa
Engine Load 17%

Under the tests page, here is the only two things I can change, which have NO affect on the way the bike is running.  Am I supposed to do something after I make a change?  Can I make a change while the bike is running?  What is the proper procedure?

Idle fuel trim: 3.1  
Adjust speed control  -10

The idle fuel trim, what does this actually do, and if I raise the number what is supposed to happen?
Same for the Adjust speed control.  Nothing seems to make any change.  My bike is idling, and I make a change, nothing seems to react.

Next thing.  I was playing with one of the maps, I changed the name to 10122 and saved it.  When I downloaded it to the ECM, it changed the name back to 10121.  WTF???  Am I just not understanding something?  I have read through all the paperwork and manual for the software and it is about as clear as mud.

Sorry for this, but my bike is sick and really needs some help.

[ChazzyB]

If you are running the latest TuneECU it did on mine too. Try earlier version if not PM your email and will try to send you older version

Hmm, I have a collection of earlier versions. Out for a ride this morning, will look later.

[metalguru]

OK Yes I can see where things have gone very wrong.

Firstly we need to see if the present TuneECU is displaying Long Term Fuel Trim, if it is not then we need to send you the earlier version which will display this adjustment as quite important.

Secondly by the look of the readings your bike is running very LEAN.
To cure this you need to load in TOR map (the Tiumph one not the modded) for your vin and set the LTFT to at least 4.2 to 4.5 as a starting point and trim from there. All the other readings are correct for a very lean set up, (suprised it ran at all). TPS reading is fine as ECU will trim to this after starting. When you reset it probably went down to about 0 to .2.

Once you get to this stage you should have a good starting point to fine tune. Please read again and again untill digested fully the settings I posted and it is not wise to change anything in the main maps untill fully understanding as changing one map can effect another.

The Idle Fuel Trim will now come into play and is a very fine adjustment (a bit like pilot screws, as LTFT is main jet on carbs) and can be adjusted for smoother idle but for now leave it at ZERO.

Idle Air Control Valve (IACV) set about -12 for a start and blip throttle, if revs come down to idle slowly then increase this number by one and blip again untill revs drop clean to idle, increasing in 1 at a time. If revs drop straight to idle or below very quickly and return up then decrease number, this controls the position of the valve to allow correct intake of air for idle.

I am still quite new to this but have spent days reading untill I feel I am competant in making adjustments as all the maps are tied into eachother to produce the eventual running. When you have reached a point that the bike is running right on the basic map and is not black smoking or lean then the maps can be doctored for your particular needs.
Thanks for the PM and let me know if I can help. The TuneECU readings are paramount for diagnosing the running and easier being remote than trying to set up a carbed bike by email!!

I need an earlier version, this one does not let me change it.

All the other readings are correct for a very lean set up, (suprised it ran at all). TPS reading is fine as ECU will trim to this after starting. When you reset it probably went down to about 0 to .2.

Here is where I am missing something.  With O2 sensor readings of .785 v and higher, that is a RICH mixture in the exhaust, not lean.  My nose confirms that it is running very rich.

Once you get to this stage you should have a good starting point to fine tune. Please read again and again untill digested fully the settings I posted and it is not wise to change anything in the main maps untill fully understanding as changing one map can effect another.

Good bit of info right there, thanks.

I am going to PM you my email address for an older version of TuneECU in case I can not find one on line.

[Sasquatch]

Can someone email me an older version of TuneECU that does not have the LTFT and stepper motor lines grayed out????

Thanks a bunch

[Sasquatch]

Nige sent me 1.7.2, I will give it a shot in just a little bit.
