Now.. we are trying to start aprillia engine svx550 with using ECU for one month.
Sometimes it works but it dosen't work about 5 hour later.
I think it is very unstable.
I don't know where can i figure out problem.
Injector placed close to intake port and i think injection timming dosen't have problem.
What problem can be exist?
please give us any advice.
