I have a 2010 hyosung GV250 EFI engine and harness. it ran in the bike. I pulled it out of the bike for a parade project. It fires with Either but will not continue running. Checked injectors good Checked Relays Good, No voltage to injectors or fuel pump. Traced wire harness for continuity things look good. i am leaning towards the ECU S&T 32900H8931 there may be a last number. the other number on the unit is ECO-08D002. I have no way of checking the unit and have not bee able to find someone that can. i also have not been able to find one on the internet. Any suggestions and thoughts

Would you be open to a carb conversion ? Far less headaches this
Or find a 2016+ harness and get a DELPHi ECU
Yours is DAEWOO , not made anymore but it is possible to find it on eBay Russia or eBay Israel
I believe since you are in the states, give WhyGoStock company a ring, they might have it locally!
Now that i have seen what you are doing , I actually want to hear it alive , that is one unique build i’ve seen with a Hyosung engine in it!

Interesting thoughts. We got the 2 bikes. Because they could not be registered in California IA due to smog, but the are a great donor for the parade Rat Tryke. To project uses the engine trans and a 85 MR 2 trans axle. So it is gear low for parades and has a reverse. I have a parade for it Sept 21 so I am getting down to the wire. One other problem I have is actually finding a wiring diagram that fits the harness. So I am step by step testing out connections. Thank you for your input.
