I've been doing my homework at the website trying to play catchup so I can get the engine management computer put together and operational. I've learned that since I bought the unit, they've upgraded to a new version. Unfortunately I can't upgrade but I can get some pieces to enhance what I have. I'll have to wait for them to get here from the UK but it should really improve things without having to modify the board later.
The one part I'm looking forward to is their new 'Power Flyback' daughter board which enhances the onboard flyback circuitry. It's basically a daughter board whith 72 diodes on it that allow the flyback voltage to be increased (more voltage=shorter injector opening/closing time). This allows the pulse width of the injectors to be set as low as 600 microseconds. This essentially solves the low rpm tuning issues when large injectors are installed. They've run injectors as big as 1500cc/min on 550cc cylinders with great results.
One other part I've picked up is an immobilizer that's built right into the ECU using an 'iButton'. It's similar to the technology used in new cars with a transponder built into the key only in this case the transponder is a small metal button like a small watch battery. You press it into the socket and voila, the bike won't start without it. And it's all built into the ECU circuit board so there's no bypassing it.
The last thing I ordered was a serial bluetooth module from sparkfun.com I'm going to connect it directly to the serial connections on the ECU motherboard and run the antenna external to the case. It's a Class 1 Bluetooth 2.0 device so as long as there isn't any interference, I should be able to program, monitor, and datalog anything from up to 330 feet away.
I had planned on digging the bike out and getting back into it this weekend but unfortunately I had some car issues I had to deal with so no updates there I'm afraid.
