The E-33, which is the US "California" version is the only version I'm aware of in the U.S. We've yet to find anyone with the E-03 non-California version. The E-33 version uses the 32920-18H20 ECU, whether it's an S or SA. I'd have to assume the 18H10 part number listed in the US microfiche is for the non-existent E-03 model.
Looks like the RPM goes all the way to 16,000 in the maps. How do you edit the headings to make things easier to read, is it something in the XML file?

We should coordinate who is doing what, otherwise we'll end up all working on the same thing. What is it you're working on? I was messing with the Ignition maps...
Like Geoff says, using 2.56 runs the maps to 16,000 RPM which to mee seems like too much for a bike with a 9,500 RPM redline. The limiter kicks in at 10k, yet the last change to the map is as deep as 10,800. Does that seem like something Suzuki would do, or is our scale wrong?
It is not uncommon to see the tables extend well beyond their usable limits.
Besides on way I find the the limiters is to first find a routine that converts crank period to rotations per unit time. It uses a unique constant that makes it very easy to find with a simple search for the constant value.
The bandit has the same routine, line for line, with the same constant that all the other 2.56 ecus have. I have high confidence that scale is correct.
The fact there is data above red line seems to indicate that someone dyno'd the engine in that range during development and perhaps this engine has some untapped potential. It is not like 10,800 is an outrageous rpm for a 1250cc engine.
Geoff, could you email me the sections of your xml code that you've changed when you're done with them? I figured I could copy and paste them to a minor-revision master (.01, .02, etc) in this thread. Then RR could post an update at the start of the sticky from time to time as our progress warrants it.
Gadget I did send something to you using the email add. on this site. Maybe it's stuck crossing the pond? I have now done some of the ignition headings too. The ignition has 20 maps. (guessing that is 10-A maps and 10-B maps) 2 are almost identicle so I am thinking we have 2 Neutral maps(1,4 and 2,3),? But why 8 other? I can see why on the GSX1k as you have different power levels (12maps 3 power levels).

Hi Blackgixxer I can understand the GSX having more maps as it has a switch with 3 power settings but the bandit doesn't (or it's not fitted) Maybe we do have the ability for on-the-fly map switching? Time will tell........... Maybe the maps are for getting home when the FI light is on? Hopefully I'll learn more as we go along. The main reason I was interested in hacking the ECU was to find a way to get the secondaries to stay open and let the bike breath. There is a lag in the throttle response, almost turbo like.

In the k5/k6 gixxer 1st and 2nd use group 1, 3rd and 4th use group 2, and 4th and 5th use group 3. This is why the TRE improves ignition. By forcing the bike into 5th all the time it forces the ecu to use the less restrictive group 3 all the time.
(a group being 1 map for each cylinder)
So the bandit is most likely (not including the neutral maps)
Found the same map in the Bandit definitions but I would like to understand what the numbers mean. Anyone have an idea? I was thinking it was Volts not engine speed but then it would have to use a number around 12v (13.5?) to mean anything......? Thanks

To be a little more specific the raw map numbers in the X axis represent a fraction or x/256.
For example 179/256 = 0.699 Now usually in the case of analog sensors this would be a fraction of 5V, but for the system voltage it first goes thru a 1/4 voltage divider that makes the number a fraction of 20V. So 0.699 * 20 = 14V
Wow, things don't seem to have changed much since I've been away. Has anyone had any luck with the Bandit map definitions? Finally have a job that pays more then it costs to live and want to start tinkering with the ECU again.
