I’m assuming that everyone who replaced the ECU did it themselves rather than have someone else do it?

I obviously cannot answer for other guys, but based on threads I've read, yes, most swap it out themselves. There are comparatively few ST's on the road and they are very reliable. A consequence of this good fortune is that few end up in dealerships or mechanic's shops. Few techs get to know these bikes well (even so called Honda trained mechanics (I speak from unhappy experience)) and they tend to botch repairs. Word has spread and most guys do most or all of their own service.
 
I can rev the bike to 8K and the FI does not come on when stationary.

I don’t trust dealers at all.

Yes. It is very easy to swap out the ECU. It is located under the rear cowl. Remove the seat and a undo few bolts to free up the rear cowl. No need to disconnect any wires or cables; just flip the cowl assembly over towards the front of the bike and lay it where the seat goes. The ECU is right there and easily accessed. If your bike has ABS the ABS control module is there too. They have different connectors so it isn't possible to connect them wrong, but I was slightly confused at first because the ECU was underneath the ABS module.

As for the light not coming on when you rev the engine in neutral, my guess is that the ECU is also monitoring the speed of the wheels. When my ECU went bad, the FI light would not come on when I was accelerating from a stop in the lower gears, even when it went above 4k; it would only come on once I got above 4k at highway speeds.
 
The ECU is plug and play. I've swapped out 8 so far this year and it takes less than 10 minutes.
You won't get the voltage failure until you're in 5th gear above 5000 rpm. You can't reproduce in neutral. Go grab a PA ECU off eBay,

Second gear 70 mph indicated is when the light comes on.

I'm not saying it isn't the ECU, I just prefer to arrive at that conclusion in a different way.

PA ECU?

Yes, a police bike ST1300 ECU. Note changes were made in '08. I forget what year your bike is, an 04? if so, anything up to a 07 will work.

My bike is an 07. Thanks for the info. :thumb:

Do you have an extra one lying around?
