May I request you make a video of this, or take a thousand pictures…..I learn by watching….
Thankyou!

Thankyou!
If the "operation" is successful, I will make photo documentation. At the moment I am waiting for new harnesses purchased on eBay.
A while back, @CruSTy was looking at adapting a 2008+ ECU to an ST with earlier harness to check if the ECU was compatible with an older ST.
Your approach is a quick way to get the answer. The 2008+ harness could turn into a hot commodity!
Still working on the adapter harness. Its near complete. Sorry the loss of my wife kinda took the wind out of my sails. If someone with an 07 or earlier ST1300 is near I could use a test bike. I can use my own but requires removal of the top box and tail which is a pain. Also my ST1300 does not exhibit the code25/26. Would be nice to have a filed one to prove the 08 fixes the problem.

Sorry to hear about your wife CruSTy 
OMG I can relate. It's been 7.5 years, and nothing is different between then and now. <<HUG>>
If another bike doesn't show up by April of next year, I could ride my 2005 over for a test. It currently shows code 26 if I get above 4k on the tach, but otherwise has no issues other than a red F1 light. It's a non - abs bike with easier access to the ECU.
Test harness is complete. Looking for a 2007 or earlier bike to test with. I would prefer one without top box mount for easier access to the ECU.

I would happily volunteer my '07, but I think we're just a tad too far apart.

Sorry for your loss!!!!
Djeeez, Joseph and Mary!
I’m a bit slow….
And I know some of us on this forum are….not naming names at this point…
More pics, explanatinion..??
Seems like you’ve done quite a work!!!

My theory to solve the lack of available replacement ECUs for 07 and earlier ST1300. I ordered an ECU for a 2010 which are readily available. I built an adapter harness to connect the new style ECU (33pin x2) to to early (26 pin x2) wire harness. If it works successfully it will give us some options for those with failed ECUs.
I will ride out just as soon as risk of ice/snow between here in NY and you. Maybe 3-6 weeks? I can be there in a day ride.

Hi again Crusty, we have had a lot of success on the Honda 1200cc jetskis that get CODE 25 issues, essentially the same ECU as ST1300, so we do the ZOMBIE mod and remove the knock sensor shield from pin A-26, dont ground it, replace knock sensor with a new one and also run an extra earth from battery negative post to engine. This seems to have fixed all the CODE 25 faults on all the machines we have tried so far. But have found that the 2007 models dont get that CODE 25 issue, this was what the Blackbird guys found as well, Fitting the latest year ECU may help you guys. Bypassing the ECU warnings on the diagnostic plug has been done in the past before we worked out the ZOMBIE mod you guys use. But this is reckless had one bypassed ski overheat, melt/explode the aluminium water cooled exhaust manifold and destroy the turbocharger in about 300 meters because the cooling system was blocked. I had the same problem occur but the warning/limit system shut my ski down after about 150 meters and saved it, so its important to keep the ECU protecting the engine. When we get CODE 25, skis go into a 3000 rpm max limit mode, which equates to about 6 MPH on the water effectively stranding us. This is on a ski that normally at WOT is 64 MPH GPS speed.

Due to ill health have slowed own on getting a fix for these ECUs, but have worked out the VFR800 and CBR954 ECU uses the same plugs and IMHO IS the same ECU as the ST1300 and jetski ECU with different programming/flash inside. So bought a couple of used VFR800 ECUs which are only about $200 normally to reflash on the bench, and if this works should be able to help you guys out as well.
Why replace the knock sensor if you are not going to have the wire hooked up to the ECU?
Not sure that's what he is saying.
He's talking about reconfiguring the grounding of the knock sensing loop, not disconnecting the sensor.
