The early 2002-2007 ECMs are physically different than the 2008 and newer ones.. There's a pic here somewhere.
ECM FAILURE POLL AND DISCUSSION

Yvan did a lot of work for us trying to implement his FCE (Fuel Cut Eliminator) and sell it to Owners.
(FCE) Fuel Cut Eliminator for ST1300 - On-Off Throttle Issue Resolved | ST1300 Related
I just picked up my bike with Ivan's new fuel cut eliminator for the ST. Throttle response is flawless. I put 210 miles on the bike today under various riding conditions from high speed riding to traffic jams. The throttle now seems more like a rheostat connected to a electric motor than a...
In the process, he became very familiar with the ST's ECU (even built his own harness to talk to it).
I was merely suggesting that if we end up having to go down the route v8-7 is talking about here
and we need to consult with an expert with ST ECU knowledge for setting it up, Yvan might be such a resource.
Are the 08 and newer not failing?
I think this is why he indicates that we would have to work on the harness to adapt to the physically different ECU?
I have seen a few 08 and newer PD bikes have them fail, but to be fair, they were on escort bikes that had a mess of jury rigged wiring which probably killed them.
Here’s a thought nobody have mentioned, could folks be damaging the ECU themselves trying different attempts to fix the knock sensor codes?
Shorting wires, not disconnecting batteries etc.
It could have been a simple melted knock sensor wire repair, but their attempt to fix it incorrectly toasted the ECU.
Just thinking out loud here.

Yeah, one reason why I had P and non-P bikes in the pole and 2008+ and pre 2008. To see if the different ECMs were better or not... obviously, 2008 and newer bikes are newer so if time is a factor it delays some of the numbers... also, I don't remember the sales numbers so perhaps pre 2008 bike sales were larger so more of them would fail, that's the assumption..
It's impossible to build a poll that covers more than a specific slice of info as everything starts skewing the numbers... but it's a start.

Impossible to prove or for anyone to admit to.. lol
Here's one... I did have to buy an ECM for my 2008 ABS... why? Lightning struck my house, took out strange things like the washing machine, not the dryer, an electric toothbrush but not the electric shaver on the same circuit.. it took out the bikes ECM because a battery tender was attached and even though it blew the fuse that had direct to the battery it must have jumped and hit the ECM via some other wire... I replaced it and it never had an issue after that. Lightning follows some interesting paths...

That's why I mentioned changing the harness to a late model harness. That will overcome that physical difference. the only question that would remain then is if the late model harness will plug into the rest of the early model bike. I have no reason to believe it wouldn't, but I don't know that

I get you... hmmm... seems like a maybe... I think the ABS module also changed... I think.. I don't know if individual sensors are different and ergo would or could send different data or voltage or whatever the sensor does...
Or find somebody to make a short x-over harness for us.
The problem may be that even if you have a computer and an interface that could talk to the ECU, if there's a hardware failure, it has to be taken apart and a new component soldered in. I'm guessing that is the issue. The fact that these people that say they can fix ecu's, but state that they can't fix this issue tends to make me think it's a hardware issue.Yvan did a lot of work for us trying to implement his FCE (Fuel Cut Eliminator) and sell it to Owners.

It would require the plugs from a late harness to plug into the late ecu, but yes, one could either replace the entire harness, cut and splice/graft in the plugs from a late harness to the early harness or the proper way would be to remove the pins from the old plugs and put them into the new plugs but that would require very careful matching of the wires and pins to the proper port. The safest way would be to change the entire harness. That way you would know if you come across sensors or plugs that don't match up then you could simply swap the plugs or get proper sensors from a late model bike
Many of us could repair these ECU's if it were not for the potting material. Our primary goal should be to find an appropriate solvent which at the same time will not dissolve the PCB and its components. If we can do that this would no longer be an issue.
I have removed potting material from a few different electronic components over the years. It's not overly hard but it's messy finicky work. My issue is how do you identify the defective component when you get the potting material off. If it's glaringly obvious like a burnt component then you're laughing, but if the component has failed inside with no evidence, that's where you need to be a computer wizard to figure it out, which I'm not.

Of course,
But what v8-7 suggested was to REPLACE the ECU with one of the standalone computers available today for that, like a microsquirt or a megasquirt. He was NOT talking about repairing the ECU.
His suggestion is for when there are no more ECUs to be found anywhere, to replace our defective, non-rpairable ones, so we have to come up with an alternate control unit.
If we have to go this route, we will still have to set up the replacement control unit, or even program it, and I only mentioned Yvan as somebody who might be able to help us emulate the ST ECU with such a computer, due to his extensive knowledge of the ST ECU derived from his work on a FCE solution.
Then again, there could be enough knowlege on this forum to tackle this without further help.
