ECU for 2007 919

I'm looking for an ECU for a 2007 honda 919. Mine still works, but the signals I'm getting from the RPM is not reading correctly

there may be a difference
38770-MCZ-671 PGM-FI UNIT $661.03
and
38770-MCZ-A32 PGM-FI UNIT $669.86

I would think its only a pin or two for Clock vs No Clock on the display. Someone else may know more.

Is this on your modded 919 with the tail bobbed and no undertail tray?

Since you chopped the tail, and rerouted all the wiring are you sure you haven't damaged a wire or plug etc? Also are you still using a stock gauge cluster?


I am assuming you left the harness stock length and just stuffed it under the new seat. Odds are you damaged it or it has chaffed through a wire somewhere. The ecu is not the type of component that just randomly fails.

yeah. I have an aftermarket digital gauge cluster. I measured the Yellow and green wire coming from the ECU and it says -.456 But the bike runs perfectly fine. I also measured the RPM wire and it says .1 I read the manual and it says at least 10.5 volts. So If the RPM is not reading right how can the bike be running perfectly. Hmmm. Do you think the polarity is switched somehow?
I will go through the wiring and maybe find a lose connection. This is driving me nuts.
