So basically with all the grandstanding you did with starting this thread you can't tell us a damn thing we didn't already know before you posted

I would figure that for a stock ECM they would use a PROM (non-erase-able) or FPGA of some kind, so that people like us wouldn't be able to modify the ECU. I figured they would only make the erase-able ones for higher end purposes. Am I wrong in this thinking? If it actually is a serial port, wouldn't some generic RS-232 cable connect without issue?

this being the case, it would seem that with the right cable to connect it all up and the right software (tuneboy) it would be very possible to directly access the look up tables and modify them as opposed to useing a PCIII to second guess the ECU..
I spent hundreds of hours using tuneboy to mod the map on my old Daytona and found it to be a very cool program, very capable and fairly intuitive..

maybe with some convincing he would adapt the program for our purposes..
i don't know if the 06 model went to the keihn (khein?) ecu.. but mine has one..

the world is filled with assholes and idiots
dare to be different

Hopefully at some point they just come from the factory with a PROM the we can reprogram oursleves.

I just don't like the idea of messing with the stock ECM....

Dattaway, I have the USB to 4 pin cable that plugs into the factory wire harness from a laptop to program the HRC ECU's. Its a spendy little box @ $375 but it lets me change the fuel setting and other items on the HRC ECU's.

I also have a few spare 2006 ECU's if you want to buy one for your ride then you can reverse engineer the one you have already started to hack into.

How much do you want for one of the spare ECU's.

The only way to find out if the ECU can be reflashed is to give it a go.
The protocol to reflash the Keihin ECU used by Triumph is different to the protocol used on the same type of ECU for KTM.
I would expect that the Honda ECU would be different again.

What is the cost of the HRC ECU and adapter ?

Thanks
