So I tried all off the shelf softwares that communicate with the openport tactrix and a cheap ch340 (or something) usb cable. It seems I'm going to need to do something else. The ECU uses a not popular protocol that I need to work on if I want to use the K-Line.

No idea what happened while I was using the off the shelf software and hardware but as I was trying to communicate with the ECU while the bike was running, it suddenly started running a little differently then the ECU let the magic smoke out. So I tore it down to see what was inside and what not. Here seems to be the main chip( RENESAS M30280FATHP-U3):


The info for the chip seems to be:


Totally not sure where to go from here. I have the ECU torn apart for inspection and I've got a new one on the way. I have a Yamaha scan tool that works with this ECU so I can see how it communicates with the ECU. HOWEVER, this ECU does not seem to support the YAMAHA CO adjust feature that is built into the diagnostic tool. If I could perform a CO adjustment (which changes the fuel curve), I could sniff the communication between the diagnostic tool and the ECU. This seems like it might be nice. But with the info on the chip, is there any hardware that works off the shelf to more directly work with the chip in the ECU?
