RidgeRacer ECU Works...
Shop just called and my bike is ready.. Bike is installed with Ridge Racers ECU and some other goodies. My mechanic hasn't rode the bike in length yet but it does run and idle. I will be picking it up between now and Monday. (its been raining). I will post findings on Hacking The Planet as I go..

Thanks for the update. I'm sure many of us are anxious for the details.

Glad to hear that, not that I had any doubts 
Be interesting to see if you notice any difference in first gear with the first gear only map removed. I'm sure I don't need to tell you to take it easy the first time you take it out.

RR, whats the prospects of changing the ecu to fire two cylinders at a time? Is there a table that tells the ecu when to fire the injectors and coils besides just the timing map?
For instance if i wanted to fire 1 and 4 together and 2 and 3 together etc.

is that what they call a "big bang" motor Y2K?

For instance if i wanted to fire 1 and 4 together and 2 and 3 together etc.
Depends how many degrees of crank rotation separates the first pair from the second pair.
The system is set up to fire each cylinder only once per 720 degrees or 16 crank sensor pulses.
When the ECU software starts up it loads a number between 0 and 15 into variables for each cylinder's coil and injectors that represent the crank pulse count they are supposed to time off of. For example;
Inj_1 = 0
Inj_2 = 4
Inj_4 = 8
Inj_3 = 12.
It would be very easy to change those numbers to
Inj_1 = 0
Inj_2 = 8
Inj_4 = 0
Inj_3 = 8.
The only problem I see is the system was designed to have to only process one cylinder at a time. If you changed it the way you suggest then each time period it would have to look up and process two fuel maps, two air maps, two throttle maps, etc. At really high RPMs it may not have enough times to calc the first pair before it was time to start the next pair. The only way to know for sure would be to try it and find out.
The short answer is yes you could do it but it would be a lot more involved than just changing some map values like you do to up the rev limit.
