RE: K7 project documentation notes


Yes please, I am interested to receive all Gixxer ecu versions. What I need is:

- Exact manufacturing year (e.g. K8) and model (GSX-R1000) of the bike.
- ECU part number (e.g. 32920-xxxxx)
- Any special info known about the ecu (e.g. restricted to 100hp)
- .bin file unmodified

Please send me your file to: ecuhacking@tikkari.net

I will compare the bin to known sources and if different will add it to file/new list.

Thanks in advance !!!

A new version of ecueditor.com is now published with all latest features. THIS IS FOR TESTING ONLY AT THIS STAGE. If any problems, start with file/new and flash that to the bike to bring it back to stock.

As we are already at the subject of blocking any kind of errors.I have one proposal.
Lots of drag racers throw out secondary throttles.I saw in GEN2 possibility to disable it.
I have demonted them mechanically but sensor and electric motor are still there.

Yes, and the secondary throttles is the best way of tuning the bike for a very linear power curve. The STP map has both STP opening as well as FUEL reduction maps there - so out of everything else that would be the last way to change my bike.

Think the STPs an ability to:
1st and 2nd gear - tuning for maximum possible acceleration without fighting the front
3-5 gear - tuning for most linear throttle response for exiting the corner
6 gear - tuning for best power by adjusting the STP angle.

Its our experience that with highly tuned all motor hayabusas that:
- STP angle is needed for best possible power. Removing STP plates just reduce top power.
- The torque is lower without STP plates, for best mid range torque STPs are needed
- The power curve has peaks without STP plates which makes the engine response to throttle movements somewhat tricky. With STP tuning the power curve can be made very linear without any bumps meaning that the response is always predictable.

This should be in FAQ, can I remove STPS with ecueditor - its ill adviced, something the tuner should only doc if he wants to make the bike slower and more difficult to ride. Therefore this feature is not supported on ecueditor.com.

---

But of course - there is several ways to think about this and some just disable STP because of turbo, others just for simplicity. We all do what we believe is best for the bike.

No more questions...:):).
I have still more to learn...

One thing.I saw that You have activated function of quickshifter.
It wont work with quickshifter sensor that are NC.You will put all the time 200ohm on the input.
It can be used only if DSM1 or DSM2 input mode is active..

Questions are always good - my opinions may be sometimes very strong too. But about STP:s thats one of the unused weapons in stock ecu, which have not been tuneable previously so its only natural to take those away....

But please always ask and also question what I am doing, its only the critisism and feedback that really brings the essentials to the knowledge of us all. Also its the feedback from the user community on this board and above all the feedback from racers (over email or spoken words) is what determines the direction that ecueditor.com development takes. E.g. on the hayabusa side there is a poll ongoing about what should be done next.

Btw - just tested on desktop (with shifter code in hayabusa ecu) that:
- Gixxer shifter module with resistor activation works
- Gixxer 2 step limiter works (this is the limiter that is active when clutch is pulled in)

Name: ecueditor.com for Hayabusa K2-K7, K8-, BKing and Gixxer1K K7-
Version: 2.5.1.29

Hi,
Something very useful to add is the function on busa editor that disables the ram air maps.

On my 2008 1k I have found that the B and C mode do help in the rain during street riding. Even in C mode I can spin the tire in the first 3 gears but, I have to try a lot harder to do it. Also, I have found during cold weather the back tire has terrible grip and the reduced power setting really helps cut out the surprises. Lastly, when hauling a passenger, the C mode makes it easier to gently transition from being stopped and going through the gears so as not to scare the passenger.

I have made a programmer and I plan to try the new editor soon. It is going to be interesting. I can't thank Petrik and everyone envolved enough!

About steering dampener - I believe the flags that enable/disable steering dampener and related errors could be these:

unsure_steering_dampener_switch_unk_62AC1:.byte 0xFF
unsure_Steering_dampener_switch_unk_62ACF:.byte 0xFF
unsure_steering_dampener_switch_unk_62AD2:.byte 0xFF

Now just need to find a way how to test these...

At the weekend I'll be able to do any road test you want at my bike. Tomorrow I'm going to built the cable and flash.
My ecu is 32920-21H00.
Can I flash the ECU with the program of an other model?
The EE doesn't have enable the advanced settings for the 32920-21H00

Excellent !

Have not had time to look in depth to 21H00, that is very different to 21H50/60 which are the same. If the 21H50 firmware works just fine in 21H00 dont see any reason why further develop that as its a some effort to update several models. Basically each screen needs to be copied and program modified for a new model.

Really looking forward to receive the K9 bin (ecu: 32920-47H00) to see how different that is. After that we can decide what is the strategy on which firmware is used as development platform.

Got feedback from Nikos/Greece that using 21H50 firmware in 21H00 ecu may cause the ICS error. 21H00 in 21H00 ecu works fine. If that ICS FI comes on then the first step is to try resetting ICS using the engine data screen. There is a button at the bottom of the page. If that does not help then testing the ICS disable. Lets try to find a solution for this over the weekend then if it happens to you too. I will try to find some time to find an easy way to test the steering dampener too in 21H50 firmware.

EDIT - even gen2 hayabusa firmware works according to several reports in gixxer - anyhow the fuelling is off requiring at least the IAP map tuning.

Ok.
Today i've installed everything.It took about 30min to complete everything with harness.
Engine data works perfectly but i meet one problem.
After VERIFY/READ it showed lots of differences beetwen image and opened map.
Program didn't save uploaded map and showed an error.
I have 21h50 ecu and k8 1000eu version

 sorry haven't had a chance to look yet, but Ryan Schnitz mentioned the limiter wasn't programmable high enough when using busa firmware on the gixxer code, just wondering if that had been raised?

Thanks - now I understand, the ecu id on the screen is most likely the map in memory and your ecu is a new unknown type.

Made a new version (Version: 2.5.1.44 ) of ecueditor.com which should allow saving this type of image.

I have already saved an image of my ECU.
I can send You for compare.
Those are numbers from ECU.

32920-21H50
112100-5972
NEP0m0

K8 EU (proably imported from Spain).

Best Regards.

I flashed all maps at the 21H00 and everything works.
I had a problem with the idle(2000rpm's). I flashed again the 21H00 map and it was still revving 2000rpm's and set it at around 1150 from the idle speed. I'm sure that it wasn't at the stock setting. It seems that everything works fine.

No road test tonight.

Tomorrow I'll go for a ride.

Is spain 100hp limited ? If that is the case, please send me the .bin just to check out how that was implemented...

I just came back. 21H50 map from k8 also works at 21H00.
The only problem is that the idle speed after download the k8 map is at 1700rpms.
But this might happens because somebody had tried to do throttle valve synch with out SDS tool.

If I disable the ICS then I can adjust idle speed like the earlier models?

What is the SD?

SD = steering dampener. Not tested, just added yesterday for testing.

Disabling idle should allow "old style" idle rpm setting.

There is a button at the bottom of the enginedata screen to reset the ICS to be tested.

I try to find the difference between K7 and K8 idle features to make an user setting for this. Could you send me the 21H50/K7 and 21H50/K8 as it sounds like K7 works, but K8 has different ICS base value. (EDIT - just realized that most likely ecueditor.com embedded files were used so I need to look from those wink.gif

I've checked Registration Certificate and the bike was registred for the first time in 11.09.2008.
VIN umber is JS1CL111100110641

First feedback.
Already flashed.
No errors..
2 step limiter-works perfect..
NOX sensor off---as above (already sensor eliminator removed)
90-95 fan on off don't work..im trying right now other values..
will see what happens..
Tommorow i will put Zeitronix DataLogger and will see what happens with AFR..

Regards.

21H60 works in 21H50 ECU..

Something is in threeshold of temperature not correct.
I'vet set it on 95/90.
Fan just started at 95 and stopped at 96 and temperature  went to 105
At 105 fan started again to work.
And after2-3 minutes everything just crashed and FI (ign lock) stoped the engine

I tested at 0 klm with the front wheel on the air. I set 99 value to check how hard could it be. It was softer than a K1-K6 OEM steering damper.

That's why is better to disable SD and put some aftermarket one.
Ohlins SD was my first investiton..biggrinbiggrin
I'm curious what kind of analog output is it.
If we have a normal coil which regulates flow of the oil then it should be 0-10V.
This output can be used for other purposes.evileyeevileye

Lets try to get some proper testing done with steering dampener adjustment. There may be a slow speed threshold preventing it operating so rearhweel on stand at then some testing of the higher numbers.

If you look how the busa nitrous module operates. Is it similar you would be after ? Only one relay that connects to the pair output as nitrous control solenoid.

I tested with the rear wheel on the stand and speed until 80klm.
I tried different values 0klm-99, 20klm-0, 40klm-90, 60klm-50, 80klm-99.

The SD seems to be the same at 0klm and at 80klm which had the same value.
The others were as they have to be. The value of SD duty change the time that the klm pass its value. It doesn't works analogically when reaches a value.

The SD is at perfect condition. I had problem with the front end while accelerating even at speeds over 200Klm, it was very soft. The same problem had some friends and replaced it with aftermarket.
I already have download a map with more tight values but I can't test it tonight on the road.

I test the SD with very tight settings at lower speeds. Gradually tightening the SD from 20klm until 200 klm where it is set at 94value. The bike is better and the front end problems have disappear. I want to test again at a very bumpy road.

Could you guys compare your dyno rpm (only if measured from engine, not rear wheel) with the ecueditor rpm. Would like to check that the reading is correct.

I believe PetriK is referring to the datastream RPM reading in ECU Editor when connected for engine data. In order for the software to interpret it in teh datastream, a variety of calculations are used and there may be room for a little refining of the constants used in teh multipliers.
