You sure? Every time I mod someone's ECU they seem to disappear. 
I think the Rev Limit is pretty much a proven thing.
Are you going to get a BDM adapter and do your own map changes? What would you like to do with it?
I think the next thing I would like to explore is the A/B map feature. Being able to switch back and forth between maps would be great for testing. You could test map changes back to back switching between your stock maps and your modified maps.

I am an idiot, so I don't know what a BDM adapter is......................But I can see about getting one and go from there. I just might end up learning something about computers.
I was thinking of maybe testing timing. I have a PCIIIr, so I would first make a dyno pull with timing in using the PCIIIr on a regular ECU, followed by taking timing out and doing a pull
to show no added timing, with a final pull using the RR magic ECU.

Had a PC3r a couple of years ago with intermittent problems until i donated the connectors for LM1 to tune the ECU ... and finally opened the unit to see how it works.
Please remember to disconnect the pc3r completely to avoid it confusing otherwise perfect ecu.

Saw today the ZX14 ECU. Its mitsubishi unit which does not necessarily have AUD port for getting the flash image out from it, but we still are possibly considering to open it just to see if there are other possibilities ?
Anyone yet opened one to save us from the trouble ?

It seems that until I figure out an easier way to tune the ECU real time all most people are interested in is upping the RPM limits. Same thing goes for the 16 bit Busa guys. Unless someone is doing something out there and keeping it to themselves Entropy???
Anyway I was doing a busa for a guy who just wants a one time rev limit mod. So I decided to just do a 'Slot' instead of a 'Notch'
I expose just enough to solder temporary pins onto the connector, reprogram it, remove the pins and seal it up. That got me to thinking that what I should do is cut a similar slot on the other side just big enough to fit the plug into. It would be a much cleaner, less 'scary' looking install. You would end up with a coin slot like opening on top of the ecu that you would slide the programming plug into to program it instead of chewing a big bit out of the back of the ECU.

FIRST LET ME SAY AWESOME WORK TO RR AND EVERYONE ELSE INVOLVED!
I have read the whole thread but it has been a while, I want the a/b function an my 2002 zx12 my 2006 busa and zx14 not sure if that has been done yet OR CAN BE DONE ON ALL THESE DIFFERENT MODELS?. also would love the ability to tune without the power commander.
the a/b map function for us drag racers is my first choice. it would be so much easer when I want to spray then having to go get my laptop and change maps.
LETS NOT FORGET ONLY THE PEOPLE READING THIS KNOW THIS CAN BE DONE!
we just had are awards banquet and I was talking to 10-15 other bike racers and mentioned something about this and all of them wanted to know more!
AGAIN THANKS AND LET ME KNOW WHEN YOU ARE ABLE TO DO THIS A/B SWITCH

Actually I was going to do some work on that today.

The A/B switch for the ZX-12 is a done deal. I've tested it on the bench. Only thing is you have to turn the key off between maps. Doesn't sound like that is a big deal in your application. Of course WHAT to put in your two map sets is still being worked on. The Ignition maps are pretty straight forward but on the fuel stuff, as far as I know, no one has tried to tune yet.
On the 2006 Busa your also in luck. PetriK over at my ecu site
http://www.activeboard.com/forum.spark?forumID=99460&subForumID=392256&p=2
who also has a 2006 busa, has been making a lot of progress. It turns out its even cheaper and easier to flash the newer busas than the older -12s or older busas. If you had any questions about your 06 Busa he would be the guy to ask. Just yesterday he posted how you can use the ECU airbox flapper solenoid output of the ECU as a shift light or nitrous rpm window switch. I believe he has also figured out the A/B or MS (MapSelect) and bench tested it on his busa.
On the ZX-14 they have Mitsubishi ECUs and they have turned out to not be very hacker friendly. They have the same CPU as the 32bit Busa. These chips can be flashed thru the wire harness without cutting open the ECU. However while you can WRITE to them you can not READ them this way. In the case of the Busa you can cut it open and expose a port to READ the code out. Once you have the code you can flash any other busa of the same type without opening it up using a simple RS-232 cable and free software.
The ZX-14s have no port inside to read out the code. Essentially you would need to literally cut the cpu chip off the board and stick it in a PROM Programmer to read it. So to start with just to begin with the ZX-14 you would need to destroy 2 ECUs, one for code, one for test. You would also have to repeat that process for each model year.

keep up the great work RR!
just going to throw out an idea. i know the fuel maps are still a work in progress for the ecu, but would there be a way to tune the fuel map of a power commander on the fly with a wideband O2 sensor? (LM-1 or Wego 2) as in you set a desired AF ratio, say 12.5:1 and based on inputs from the O2 sensor it would change the map in the power commander automatically to get you the AF ratio you wanted. basically you go for a drive and it "auto tunes" to a perfect fuel map.
i may be way off base, but i thought something like that might be interesting

Actually what you are describing is what I want to do with the ECU using the three available analog inputs. Either on the dyno or on the street generate an offset map. The only problem is at some point once you've generated it you need to flash it into the ECU memory. You can't do that while the bike is running.
You would hook a laptop up to the bike and drive it to 'learn' the perfect settings then pull the bike over and have it 'memorize' what it just learned.

Hi all,
This has been a real good read, has anyone done any real mapping on the 99 busa's other then the rpm limits.
Thanks

Rick,
I PM'd you about the site.
As for the 99 Busa not a lot has been done on that. The Busa ECU I have (32920-24FD0) is actually a 2001. I modified the rev limit on another guys 2000 Busa (32920-24F21) so I have a copy of that software/map. I hear the 99 (32920-24F20) is similar but I have never actually seen its map and as far as I know there is no map definition file available for it yet.
You could be the first

RR about the kill feature, would the kill time be able to be adjusted manually, or would it be all software controlled? it would be nice to have a little tiny dial to add or take away kill time like the "regular" kill boxes on the market

so i uploaded the map file asper instructions and it got it and i followed where they went (both of them c1 and k1) .
then i turned on the bike. nothing but head lights. o crap(i said the s word)
then i figured i may as well follow the downloading instructions before i freek out. yeah it worked.
so ii have saved and written a map to my bike. yes it was the same map i pulled out , but i did it.
i can not convert the .bin to .s19 as of yet my computer says no when i try to convert.
i just tryed to fire the bike with the bdm adapter plugged in and no injectors. i now can not remember if i tryed it with it unplugged. i am 80% sure i did but am not 100% sure.
also i noticed it goes online with out the programming power connected. now i am not going to try to program it. i will not be that guy with only one spare ecu.
SO HERE WE GO...

so i added to the A map. the volumeteric eff part. and boosted the # that were very different than the ones around it. RR thinks this is the lean spot for the freer flowing exhausts that run bad down low. so here we go. i loaded it in and then pulled it out to make sure the map i put in was there. now i need to make the cpu run on the A map and put on the rest of the plastic and see how much i effected it. if i did in fact add fuel to the bad spot which i got fairly nice with my doceck tuner it will run real rough at around 2100 and sort of lunge like it does when i dial too much fuel with the dobeck. if it does what i am hopeing, i will turn off the dobeck and tune from there. i just made the # sort of match the ones around the wedge area that was way low. need to start someware anyway. maybe i'll get to ride it early this week. we could not buy a raindrop all summer for the most part and now it rains every couple of days. (o and it needs to not be stupid cold)

keep us updated on the progress red rocket.
just think what this is going to do for all the guys out there running "shitty" muzzy pipes. the muzzy is going to work the best of all them in the area they are known to be "bad" for. all because the ecu is tuned for a restrictive exhaust, and the muzzy is doing what it does best, getting lots of air moving out....

so i rode it today and put fresh fuel in. i can barley tell a difference from map B to the modded map A. both are nice in this weather though A feels better. when it is 40ish i notice it runs better then when it is hot out and it is leaner (with out adding fuel). so the real test will be in a couple of months when it warms up.
who knows i may need to take some out. i need to get it on a dyno now.

after i rode it and it did not change the way it rode from map A to B i was thinking and called RR to ask how it gets its vacume numbers and then i put a vacume guage on it. it idels at around 20 to 22 cm hg. i was changeing the numbers from 900rpm to 3200rpms in a range that it will only get to while decelerating. so i bumped up the numbers in the -14 to -22 range though after running it at around 3000 in neutral it gets close to 30cm but under power i doubt it will get there due to the fact of haveing more throttle open due to the load for the same rpm.
i am velcroing the vacume guage to the bike to ride it and watch where the issues are. for the most part i am going to watch rpms and cm-hg and i should be able to get close to the area on the map where it is not operating nice.deduct about 90rpms for every 1500rpm
i need to make a orifs with a small hole (like .050 i think) to smooth out the needle. now i pinch the hose closed a tad to get it steadier.

it does hold a given lower rpms like 2200 eaiser so i did go in the correct direction i think. will not get to ride for a week or so due to weather.

i rode the bike today with a vacume guage on the tank. i need to add fuel in the chart from
-2.9 to be safe all the way up to where i stopped. i also do not think just bumping the numbers up say 4 makes a big difference though i did all the stuff above where i was actually rideing vacume wise. it seems to sort of dog say 2100 and -7cm vacume. i am going to target that area on map a and just get stupid on numbers on map B so i can try two different things on the same rode trip. though that will kill the consept of switching back to the "working map" to get home. maybe tomorrow.

added too much fuel. actually started and ran with out stopping when cold. usually i have to re start it a couple of times. but driveing around 2100 was too rich. i could hear it warming up. i learned something. (and got to ride)
