Bozo(Mark),

I read your posts on SV down under. Wow......you spent some serious time on those SV ECU's. I was wondering....did you ever get to finish the 650 ECU? Thank you.

Jason

No I never progressed much with the 650, sorry. Am only just getting back to the 1000 after the best part of a year.

I'll keep up with your work through the posts on the SV site.  Maybe someday somebody will be able to reflash it!  Happy New Year and thank you for your reply!

Anybody knows why there are 8 maps in speed density and alha N tables? THere should be 4 as I understand, cyl 1, cyl 2 x 2 (ms1, ms0) and there are 8, like 2 for each cylinder...

Psyche please respond me to me email i wrote you I would like to talk a bit about few things we discussed earlier and also i would like to look thru SV definitions more advanced than raw ones

What is the 32920-????? number of the ECU?

Can you post the bin / XML?

A quick look at the software should answer your question.

sure thing:

32920-16GK0

Link to rar with raw xml and bin file all done by bozo:

http://www.2shared.com/file/qh5Y8j5E/BIny_i_defy.html

So quesion is why there are so many maps in Speed D, Alpha N and Ignition sections? There should be less if there are 2 cylinders...

I was not able to find Ignition groups either and also fan temp(there were 4 same values and i am not sure which is for fan for sure)

Thx,
Marcin

That xml didn't have any defined maps in it.

The x23y36 maps are the ignition.

They alternate cyl 1, cyl 2, two cylinders per gear group Neutral, Group 1,2,3,4, with a duplicate set for MS1 or

MS0:1, GroupN:4, Cyl 1:2

MS0.Group N.Cyl 1
MS0.Group N.Cyl 2
MS0.Group 1.Cyl 1
...
...
MS1.Group 3.Cyl 2
MS1.Group 4.Cyl 1
MS1.Group 4.Cyl 2

The group is selected at 0x2E4d3 but the group select values are 1,2,4,8. Stock 1st-4th use group 1, 5th and 6th group 2.

Like many Suzukis there are two groups of fuel maps. The first can be considered a neutral / fault map, while the second is the normal operating. Sequence is

MS0:1, Group 1:2, Type SD:AN, Cyl 1:2

MS0.Group 1.SD.Cyl 1
MS0.Group 1.SD.Cyl 2
MS0.Group 1.AN.Cyl 1
...
...
MS1.Group 2.SD.Cyl 2
MS1.Group 2.AN.Cyl 1
MS1.Group 2.AN.Cyl 2

Well I am a bit confuesd...

So there are 4 groups, but stock ecu uses only 2 gropus right?

I recognised Alpha N maps under x23y46 and Speed D maps under x21y46 and as you say it is only in x21y46 as labeled right?

What about fan control? There are 3 or 4 values in HEX that could match:/

Ignition has 5 groups if you include Neutral group. Neutral, Group 1, and Group 2 are used.

I recognised Alpha N maps under x23y46 and Speed D maps under x21y46 and as you say it is only in x21y46 as labeled right?

 

Not sure what you are asking here...

Hmm, so Gears 5 and 6 are still not using the most powerfull map it seems:)

I mean:

I was looking thru this bin file and as i opened x23y43 catalog i thought that it was all Alpha N maps and also opening x21x43 i thought that there were Speed D maps (i was comparing them to Gixx 1K 05/06) THere were 8 maps in each catalog.

So i was curious which is which as there are only 2 cylinders:)

Here is how I listed them in the map lookup table. The C# is cylinder, the last number group.

Great now I understand it all;)

Last thing - the Fan. Any ideas how to state which values are responsible for sure?

If you want to know for sure you trace the suspected value in the disassembled code (IDApro) and see if it is compared to the Engine Coolant Temperature sensor voltage converted to Celsius and sets a flag that when traced turns on/off an I/O port pin. That's what I would do ;)

I took a quick look and couldn't find any fan code. You sure this bike doesn't have a thermostatic switch in the radiator. Do you have a link to a manual?
