That 24 pin ic = 5-Channel Gauge Driver with Serial Link
Apache Tomcat/6.0.26 - Error report
If you look at how it communicates you may be able to interpret what the ECM is saying and use the data directly from the serial data link to the display. The downside is the data likely comes from the that 100 QFP which doesn't pop up under findchips.com.
However there is this thread that came back to life - Lets just say people have been creative! Yamaha FI Diagnostics tool - ECU hacking
Motorcycle black box. Part 1 : data acquisition with Arduino Mega. | Iwasz
Fantastic info! For some reason I never made the connection that the ECU probably communicates via serial...I will probably take another stab at using my circuit to read RPM and speed when my schmitt triggers arrive in the mail, but this is intriguing, and could make 'reading' the info from the bike very simple once the tx/rx pins and baud rate are determined.....well there goes next weekend!
