OK you ECUguru's !! went to do the, IFT to zero, LTFT to leanest it will run....

and found me bike is messin about with the settings itself ??

IFT 0.0 / 0.0

LTFT 4.6 / now 4.2

IACV -1 / now -5

Have you set the warm up map to zero? Rest of it is fine as it has knocked out the CO sensor, that is the usual culprit for the values changing, could try going up in value a lot on the IFT, I am running about +30, it is a very fine adjustment so you won't do any harm even up to +99! Have a read on page 1 about setting the IACV as these can be very frustrating to get right and can also contribute to your variations.

UPDATE ON PAGE 1 IN VIOLET

[metalguru]

Been playing again this week to cure some little niggles in my map. Although it is a TOR (10173)  for the later 955 it still has some bad points like uneven idle, weak mixture through the range, Co sensor at idle.

Here are my latest settings which give smooth idle, good pick up and town riding with out any on-off syndrom, good mpg at cruise, hit 6k and it pulls the front wheel up in first 3 gears, loads of mid range power, lots more acceleration from cruise without dropping gears, running 19t front.

Noticed faster more powerful acceleration when opening up at 100MPH in top.

Fuel consumption at steady 90MPH = 48MPG (UK).

Average over 1 week of varied speed and roads = 53.4MPG (UK).

Knock out Co sensor at lower end of A/F1 map but leave working at midrange to give economic cruise. (Explained on page 1).


INJ PULSE= 1.956  1.954  1.962

Engine Load Idle = 22%

IDLE FUEL TRIM = 19.5

SPEED CONTROL = -18

LONG TERM FUEL TRIM = 4.5

WARM UP -10=0.25   -4=0.25   4=0.20   14=0.20   24=0.15   34=0.10  44=0.05   54->130=0

TABLE F Throttle position 0->13 and RPM 0->10500 = +5%

A/F2 = 500->6000rpm=13.00     7000->10000rpm=12.50

IDLE=-10->-4=1600   4=1550   14->44=1500   54=1250   64=1200   74->130=1200

This may not work on your bike as well as it works on mine as Tiggers can be individuals too.

So have you just set a/f to be 13.0 across the board below 6,000 rpm?

[metalguru]

That would be the A/F 2 map only. As opposed to A/F1.

Can't figure out how to get screen shot of A/F 1 so took a picture, hopefully some one will pop in to put me right!

Ah, missed that. But isn't that standard for A/F2?

[metalguru]

It is quite close but after trying some modded ones which were good but MPG was 29 @ 90MPH! Now av45-48. Mine seems to run ok with this although there are small changes to improve lower end and knock out Co sensor but keep economy for cruise.

CTL + Print screen will get you the screen shot

I notice that yours runs leaner above 3K revs is it still a bit snachy around this rpm?

Thanks for the hint for print screen.

Tha removal of the snatchiness is down to the 'F' table alterations, LTFT, and chain tension. Trouble is with fuel maps is trying to keep a happy medium between economy and power, I was resonably happy with the power delivery and not happy with the overall delivery. After hours of reading dyno graphs and studying other tuners findings with a bit of my own knowledge as an engineer I came to the conclusion that the TOR map is ok for my riding style but was obviously stifled for emmissions. Using this theory and lots of small adjustments (no dyno) the economy for cruise is still retained but when needed uneconomic delivery can be accessed. (More than 50% throttle) To get an idea I used my brother as control and a certain piece of road for real time testing and timing, when I first started dabbling he could keep up and pass, but just recently he can just keep up but not pass. (CBR1000). Thought that was enough on the go map as any more tends to lift the front wheel all the time, found that the hard way!

There are still some holes in that map that need sorting but you can see where I intend to be, still work in progress and real time testing on my usual commute.

Still can't get the hang of making my P.C. do as I want it to as cannot figure out after ctrl + prtscn where it goes and how to upload to photobucket, so relied on the tried and trusted take a picture of the screen! You can guess I am not a PC geek!!! Just an engineer.

Over the past few weeks have been playing with the 'F' map and have come up with some favourable results. The changes are not as extreme as the sportier tunes for other models but enhance the running characteristics of the Tigger.
With these alterations came a smoother running for town and traffic with even less of the on/off throttle, feels more like carbs now. There seem to be a lot less in the way of vibes which were not prominant before, but still less, throttle response is smoother as is take off from standstill. Power has stayed the same just more rideable and smoother. Did not see much point altering the rest of the map as these areas seem fine for road work. Fuel consumption has not been affected and has stayed the same in all aspects of riding.
Anyone wishing to try these changes must have a reasonable knowledge of TuneEcu and its workings.
The differences are based on the off road 10173 map and the % changes are shown by the white dots in the squares. Each vertical column can be highlighted and %increased.
PLEASE NOTE IACV, IFT and LTFT will change and will have to be reset but on my Tiger it was only the IFT and IACV that had any significant change.

PLEASE NOTE These changes aggreed with my Tigger  and should only be attempted by competant users of TuneECU and may not agree with your Tiger as tiggers are individuals too.

After you press PRTSC, click on Start /Programs / Accessories and open Paint.

Click on the Edit dropdown and click Paste, you screen dump will miraculously appear.  You can cut just the bit you want from the entire dump first or you can just save it to your desktop but first give it a name and change the suffix from .bmp to .jpg as it makes a smaller file.

If you want to trim it, first click on the box shape in the top right of the tools pallet.  Then put your cursor on the top left point that you want to cut.  Press the left mouse button and while keeeping it pressed move right and left until the box covers the bit you want.  Release the mouse button.  Click on Edit / Cut and it will disappear.  Click File / New (say no to saving the original image) and when the new page appears click Edit / Paste and there it is.  You can make it bigger by clicking on the corner and dragging it if you wish, then save as above.

Close Paint and go to your desktop.  Click on the saved .jpg and it'll open in photoviewer or whatever your default is.  If you're happy with it, uplod to 'Bucket.

Thank you for your help BB most useful, may get the hang of these pc's soon!!

Just completed a 750 mile wander and the best MPG(UK) = 58.
The worst was 50. Not being one to stick to speed limits was quite good!
All aspects of riding as well as green laneing, motorway, A and B roads.
Tigger performed amazingly with no on-off throttle, easy round town, no snatching, no surging, smooth power delivery at all revs with copious amounts of front wheel lifting power. Lost the little tickle in the footrests at 6K revs.
Put the baffle but not the db killer back in and is smoother lower in the rev range.
Seems smoother too since doing the R/R rewire, but that could be just the misused brain cell!!

To go with the 2 screen shots AF/1 and F here are the settings:-

IFT=20:3

Speed Control = -14

LTFT= 4:6

IDLE
-10=1650 -4=1600 4=1550 14=1500 24=1450 34=1390 44=1330 54=1250 64-130=1225

Warm Up
-10=0:25 -4=0:25 4=0:20 14=0:20 24=0:15 34=0:10 44=0:05 54-130=0

AF/2=500-6000RPM=13:00 7000-10000RPM=12:50

Rev Limit = 9500

Fan Cut In =96

Injector Flow =285:6

This has worked very well on my bike but may be different on yours as Tiggers are individuals too.
