I have a quad yamaha yfz450 with engine XT660Z ( 2008r) on wiring loom 26 connector And ecu 5VK-8591A-00 , I installed emulator immo and does not want connect to ecu . I checked emulator on my friend's motorcycle XT660 2008, and works well. Why work in 2008 year and in 2004 does not?

the second question. someone tried to run XT660 engine on the wiring loom And ecu of raptor 700? I can buy the raptor wiring loom And ecu for 200 euros.

Thanks for the help
