Throttle is opening 100%. Just no difference from about 50%. I am trying to find someone that owns a 500 so I can send my ecu to try 🤞

Hi. Yes. Limit screw is fully backed off. Engine hits around 3400 rpm at about half throttle then does nothing else whilst opening to full. Got me buggered atm. Thanks for your reply.

Hi all. I have just purchased a mxu500i which has an issue that hopefully some on this group can help solve. It currently will only rev to 3400rpm app. Quad has 10000kms. Recently had new fuel pump and service. Since this problem occurred I have tested tps,and other sensors with no faults found. I have also introduced fuel into the throttle body via an atomiser spray bottle but it still doesn’t rev pas 3400rpm. I also have installed a timing light and spark appears to be constant. I have been unable to have ecu tested or swapped with another know working unit. Appreciate any help. Thanks Michael
