Just received a K7 ecu on my desk. Looking to test two things on this: - Does the ecueditor.com enginedata work - Can the ecu be read and written with ecueditor.com
This thread is really only for personal notes about this small project to share the info and also document progress.

When Gixxer running pin 5 = 5V pin 17 = 5V pin 29 = 17mv pin 30 = Raising milivolts from 10 to 60 when connected
So its posible that Gixxer pins are following Pin 29 is likely MOD0 based on voltage Pin 17 is a possible candidate as RST based on resistance Pin 5 function is uncertain as it is normally all grounded Pin 66 is a likely candidate for a map select switch.
As a next step I need to go to the shop and pick up Yoshbox and SDS connectors from a busa harness and build a temporary programming test environment.

The NF1 was not in stock at Heilind either. 2 Connectors are needed for desktop emulator and 1+1 connectors are needed for dyno programming cable.
If you guys buy me these I will paypal you the costs and postage for the items to me. Right now I have to time to try to hunt these by calling to various places or searching from internet so need to rely on someone locating a source. My focus for coming weeks is limited and therefore will be tightly on finalizing the SSI 5bar boostfuel conversion (1 hour initially) and then dragtools traction control for Gen2 (estimating some 20 hours work for that). Additionally I will test the programmatibility of the Gixxer ECU (appr 2-4 hours work).

Both of the "F1" varients with 28.4mm key spacing are in stock and available stateside through Digi-key. I do not have any gsxr bikes available to me. If someone can confirm the correct connector, I can order and ship to Finland.
Hooked up some temporary wiring from the busa testbench to the gixxer K7 ecu, here you are with some quick testing results...
- ecueditor.com enginedata works, gives all the errorcodes - ecueditor.com verify ecu command works and is downloading the code from Gixxer ecu right now
All this looks very promising at this stage !!!

Not really working, this is just a hobby to relax a bit...
This is now the starting point, rest should be timeconsuming hard work to get at least the same functionality as bking has. Anyone with some programming skills would be most appreciated to help with this.

Some more notes here... the limiters structure is a bit different than what busa and bking are - but should be fairly easy to convert the limiters screen. Only timeconsuming...
Hi Petrik I have a complete harness in spare is what of any help
Sorry - completely missed this message. yes a full harness would help - i would just strip the connectors off and leave 20cm wires, but I have understood that also the connectors are on the way so no reason to destroy a harness...

and the harness would only sort your need for cable connectors, the ecu connctor side I dont have extra. So maybe the orded connetors is more suited. If it would help you in any other testing I would be happy to send it to you
PetriK in the version 51 i downloaded the fuel tables only have complete numbers to 99 beyond that all that shows is 1--
nice work by the way :)
Thanks for the feedback - I think this has something to do with screen settings and fonts on the computer used. On my two different computer all numbers are visible.
Please feel free to check other .bins with file/new command too for this.

any chance you could get a photo of a ecu pin extracted from the ecu connector? Trying to figure out what they are.
Greg
Seems to be the same series as the GEN2 Busa. Busa uses the 34 pin varient though while the K7 seems to be using a 36 pin (not even listed in the overview)
Ok tried that and still the same, did have large font and back to normal, changed zoom level and no diff
The gix.com thread was pulled as they considered it advertising.WTF... if it doesn't get reinstated i will just put a link to here up as there are potentially guys out there that could be involved if they were aware this was happening..
Somthing weird with attaching links on this forum tried twice and both new post and edited post are now gone so here are the link to the images in plane text so you have to copy and paste
connector opened up http://img51.imageshack.us/img51/4018/gixk7ecuconnectordisass.jpg http://img337.imageshack.us/img337/5161/gixk7ecuconnectorpin2.jpg http://img266.imageshack.us/img266/9693/gixk7ecuconnectorpin3.jpg
anyone able to measure distance from ECU to the Yosh and SDS connectors (black 8 pin and white 6 pin connectors)? On the gen 2 busa they are located under the seat. This is where my flasher would plug in, pics can be seen here for connector type and shape www.boostbysmith.com/ecugen2.html
Not used to the terms sds and yosh connector assumed sds in this EU harness is 6 pin white with 4 leads B/W ,Grey ,O/g & W/r and the yosh one black 8pin with 6 leads red, darkblue-yellow , black-brown ,darkblue-white , darkblue-black
Se pics with centimeters on the ruler http://img842.imageshack.us/img842/2772/ecutosds.jpg http://img227.imageshack.us/img227/4001/ecutosds2.jpg
if you should wire from the black Ecu connector to the yosh connector same way as harrness goes it wold be 28cm , black ecu to sds 32 cm from grey to yosh 58cm , to sds 61cm
Hi Petrik, Glad yo see you are working on the K7 1000, just a quick question: Do you plan to add the Coil FI off feature for the K7 like you have for the busas ?
I am interested in this feature in particular for an annoying problem we ( K7 track users ) get on our bikes once we install aftermarket spark/skipping TractionControls for track use. The common "workaround" for the problem is to install the dynoJet ignition module that seems to filter off the problem, but its a dirty trick and its not exactly cheap ;)
Also another question: the base k7 map you generate on your software, is that an EU , US o CA map ?
Would you consider "Crazy" to try to tune a real world K7 Ecu at this stage ? Am i better off waiting for a later release ?
Its early days for gixxers - if your pull the ecu code from your own ecu with verify/read command then you can see from maps if those make sense to you.
If maps make sense then flashing your own program back should be fairly safe - anyhow its your call. I am quite confident that there may be errors, but those we can find only with testing.
I am grateful for any feedback from real world flashing.
rgds, petrik

The SDS & Yoshi connectors are located under the seat and are right above the ECU. I'm using these connectors to program my EM-PRO.
If I can do anything else to help,let me know.I have the stock ECU ( EU version) and a spare harness collecting dust in my garage.
And some other thoughts.
-The K7/K8 1000 and K9/L0 ECU pinout is identical. Even the colors on the K9 wire harness are the same as the k7 1000 according to the manual. So my guess is that whatever pins are for programming the K7 will be the same for the K9.
- The Bl/W wire that goes to the Yoshi plug is pin #52,I'm using this pin ( grounding it) to activate my quickshifter in the EM-PRO.

I am not sure if i understood the interfacing process... Can you confirm that for 1000 K7 the Gen2 ttl cable is used ? Same pinout ? Can i just buy a gen2 busa cable ?
Basicaly i have to reroute 2 pins from Ecu connector to Yoshbox connector ??
Thank you Petrik, Going to study the hardware right now. Just couple more questions and i will be ready to order the required hardware, download my code and start messing with it ;)
From your experience with Denso ecus, is there a "failsafe" mechanism ? What i mean, if after reading the code, changing something and reflashing, for some reasons the data get corrupted, does the Ecu remain in boot/flash mode so i can upload again che original code without the need to access the Jtag ?
will i risk to "brick" my ecu ??
Does your Ecueditor understand a k8 euro file structure ? ?
If not i will be forced to use your supplyed base map as reference and?
compare the data curves in graphical mode to find the equivalent in the k8 structure.?
Do i need to care about the checksum of the modified code, maybe bringing it back to the original checksum changing bogus values somewhere ? I know it may sound strange but i have experience in car ecu flashing and the questions i asked are common nightmares in cars world ;)
