First Look at K8 maps


My first reaction is holy crap!!

482 maps.  156 2D and 326 3D.

86 3D Ignition Maps
52 Alpha-n and 52 Speed Density (13 groups of 4 each)

I assume this is all because of the different driver selectable mode maps.

There are so many maps I can't get RomRaider to load them all at once without crashing.

The following zip holds the 1 meg binary and three seperate xml definitions for Ignition, Fuel, and misc for everything else. The way to use them is to Add all three to the definitions manager then use the Move up button to move the maps you wish to view to the top of the list. For example if K8_Ign.xml is at the top of the list and you open the binary then only the Ignition maps will be shown. To view the fuel maps close the binary, go to ECU definition manager and move K8_fuel.xml to the top of the list, press save, then open the binary again and all you will see is the Alpha-n and Speed Density maps.

These are very prelimianry definitions, no RPM, TPS, Gear, etc. Also this binary has not been checked or verified. I want to download the file multiple times and compare the files then look it over in IDApro to make sure it is as valid. In other words....

DO NOT FLASH THIS BINARY INTO YOUR ECU

At this rate RR will have the Gen II ready to be flashed before St. Patty's day!

That was quick

There's a good chance this will work on a B-King also, same engine ,same ecu maybe just different secondary control , maps and a gsxr style exhaust valve

That part was easy.  There is still a lot to be done. This ECU uses a different CPU language than the older ones so all the little tricks I've learned about the old code no longer applies. Also all the hardware is different so I have to start from scratch to trace out which Analog channels are what (TPS, GPS, IAP, etc)

Also this one flashes differently. You can't use FDT on it.

So we are at step one of many but it was the most important step.


As for the Bking I'm sure your correct about being able to flash it also.

Excellent work RR!

Any idea of the storage capacity onboard?

Might open up future re-programming space if some of the maps were eliminated? This would be WAY in the future of course, but ??

The Flash is 1M total. Even with all those maps 25% of it is still unused. There is 100k empty block between the end of the software and maps and 140k blank section from the end of the maps to the end of the ROM


Speaking of the ROM...

I have downloaded it 5 times now over several different days, it takes about 6 hours. All 5 copies came back the same as the one in the above zip. Also it appears to disassemble correctly in IDApro so until some one actually flashes it into a bike as far as I can tell it is a valid download.

RR, what are your plans regarding publishing the .idc files and working as a team to get the disassembly documented ? ... and do you have any views on documenting publicly the disassembly like I did with the K2-K7 ?

I am thinking to jump in to the bandwagon in a couple of weeks time when get the harness connectors and can get the K8 ecu to work with the engine emulator...

Well I was hoping to make some money off of the K8 by developing something like a professional version of your ECUeditor and not just for the Busa but all the newer GSXRs as well.  So of course the natural question....To share or not to share?

The reality is what one man can do another can do. I may have the jump on you now but your a determined, resourceful guy and I have no doubt given enough time and effort that you will catch up. And given all your experience with the Busa, access to a K9 and a dyno I also have no doubt you'll blow by me in short order.

So for us to work on two seperate competing Busa projects seems a waste of time. In fact at this point the smart play would for me to abandon my Busa project all together and spend my time concentrating on the GSXRs.

While I work on developing a professional map editor, logger, flasher for Denso M32R ECUs you can work on figure out all the maps, tuning tricks etc. for the Busa and put them in the public domain. Then I'll just take all your public work, incorporate it into my software, and profit from it. Hey, better me than some lurker who has contributed nothing to this project. Keep it "in the family" so to speak. 

In that case it is to my advantage to share what I know with anyone who is going to put their results in the public domain.

Or perhaps there is a better scenario from which we can both profit that I haven't thought of.  What are your thoughts PetriK?

My thoughts are as before - just developing a tool for tuning my own bike and let the others enjoy of the findings. On the other hand, like said over in private in past and now in public - which ever route you take I'll try to support it.

If ECUhack has a closed board available some of the research work could go there. I too hate some chaps stealing the IPR:s from here into their commerical products without even thanking like has happened in the past. This is not to deceive active users over here, its to protect against those who say nothing but read everything. E.g. you down under you know who I mean.

I do have one commitment which I would like to keep - that is to let DaveO:s family to share the finidings and hopefully let them have a share of any of the profits. But that is a wish - everyone makes their own decisions.

For me writing ECUeditor is a taskful thing to keep updated just by one man band so if there is a better tool I am happy to contribute towards that. My plan has always been to give out ECUeditor to anyone or a team who is willing to continue maintaining that functionality. That is and has always been a proof of concept by someone like me who is not software engineer.

If you have skype, do give me a buzz and we can talk what to do...

Having spent most part of the yesterday with Busa ECU I have verified from programming the initial information from Hans and I must say that it looks very good. In addition to source code from RR we also have a preliminary definitions file to work against. Most parts of this preliminary definition file I was able to confirm yesterday - so its all down to get the testing rig working to validate all the assumptions made.

I think one picture tells more than words in this context - all credit to Hans !

and with 2 sets of injectors, you would think maybe doing boost compensated fueling with 1 of the 2 sets would be AWESOME!

There seems to be 6 addresses where 15H00 and 15H10 differ, 00 being K9. This much better than with gen1 where we had much more differences.


15H00vs15H10.jpg

EDIT: 7D0F0 is of course 7D0FF as address. made a mistake on the table.

I flashed a K8 busa ecu for a turbo drag bike. I disabled all the fuel limits and set the ignition limits to 13,000. They took it racing and said it worked as expected.

I also did a GSXR 1000 k7 but have not heard back about their results yet.

On another note, the company I have worked for in one form or another for the last 25+ years apparently is no longer in need of my services. On the plus side this means I will have a lot more time to work on this project.

In the mean time if any of you need any simple, non fuel, flashing done for rev limits, speed limits etc. I would be willing to do it for a reasonable fee.

Email me for details.

thank you again rr,we will be testing the prostreet 1000 at the next  race,on the same note,last wednesday the rider for the turbo busa is a local to our home track and he was there testing his turbo grudge bike and he said that he cannot believe how hard it pulls above 11,600 and they DID NOT LOOSE A SINGLE HEAD GASKET!!! in which before the flash was a common problem.....smile

This is very good. I am sure that there is a lot of demand for this service which is now also tested in real life environment.

Hey RR i combined all three into one (FUEL, IGNITION, MISC) and got it to work with romraider..smile
